Waste systems

Which drain is recommended for an XXL shower system ?

The RainDrain XXL drainage system (item no. 60067000) is recommended for a large overhead shower, for instance. Drain performance is 51 litres/minute, in accordance with DIN EN 274.

The test inlet on my Exafill/ Exafill S does not close completely, why?

The test inlet must not be completely leak-tight. This is the only way to make apparent that the mixer must be closed or the iBox universal must be plugged up. The reason for this: There must be no shut-off valve installed after a single lever mixer (cross-flow).

The jacket pipe of the Flowstar siphon is too short. Can the siphon still be used?

Yes. The siphon can be used with a longer immersion pipe (200 mm) and pipe cladding No. 96553XXX.
The additional pipe cladding is pushed over the existing one and clipped into the spigot nut.

How should I secure an Exafill waste set connected with the iBox universal?

When connected with an Exafill, we recommend using a pre-fab set with integrated safety combination. The iBox universal must then be installed + 280 mm (centre) above the highest possible dirty water level according to DIN EN1717.


How can you uninstall the fittings from the Axor collections Axor Terrano, Axor Carlton, Axor Citterio, Axor Citterio M, Axor Montreux, Axor Uno² or Axor Uno?

The fittings from the Axor lines Axor Terrano, Axor Carlton, Axor Citterio, Axor Citterio M, Axor Montreux, Axor Uno or Axor Uno² can be uninstalled by pushing a pin through the hole using a thin object, e.g. an allen key (2 width A/F), while simultaneously pulling the holding part forwards.

Lotion dispenser does not dispense lotion any more. What can I do?

If you have not used the dispenser for a while, the lotion may have dried out and gone hard in the pump. Clean the lotion dispenser pump by soaking in hot water and rinse out afterwards.


Can the connection hoses be replaced on standard mixers?

The hoses can be replaced on all standard mixers (basin mixer, bidet mixer and kitchen mixers). Please refer to the installation manual enclosed with the spare part for how to dismantle the mixer hoses.

How can screw-in hoses that have been too tightly screwed into the base unit be dismantled?

The screw-in hoses are screwed into the mixer unit from below only by hand using a low tightening torque. If the hoses cannot be easily unscrewed by hand for disassembly, there is the option of inserting e.g. welding wire. The welding wire stops the hose from turning which makes it easier to dismantle. Now dismantle the hose together with the welding wire.

How are the supply hoses replaced on the Axor Arco basin mixer?

The supply hoses are screwed into the basin mixer from below without any extra tools (right-hand thread) and are sealed using O-rings. To replace them, the old hoses are unscrewed (anti-clockwise) and the new hoses, item No. 96507000, are screwed in clockwise.

Is there an option of installing the bath tub rim shower support No. 28307000 into a thicker shelf support?

The bath tub rim shower support can be extended by 35 mm with shaft extension No.13898000.
Alternatively, the installation surface below can be lowered (min. 55 mm).
Observe bearing capacity/tensile strength!

Can the lever/star handles on Axor Citterio mixers be aligned horizontally and vertically?

There are three possible ways to align the lever/star handles on Axor Citterio mixers:
1) on the toothing of the actuating shaft,
2) at the internal hexagon of the connection shaft,
3) by turning the handle parts towards each other.
You will find the precise procedure in the relevant installation manual.

Coolstart mixers: Why can the handle be moved slightly past the centre position to the right?
Tolerances on the base set, the cartridge base and the cartridge have to be factored in for the handle to always remain directly in the middle when the mixer is turned on or off. During the screwing process, the cartridge turns varying degrees to the right depending on the recess in the base set on which the cartridge base is fixed, the cartridge noses which engage with the cartridge base, and different clamping nut torques. These tolerances have been factored in, resulting in a slight play to the left. If the mixer were not implemented in this way, then the handle would not necessarily be in the middle for the cold water position. However, the user is guaranteed to get only cold water when turning on the mixer in the central position.
The seal between the non-return valve cartridge and the angle valve on the pressureless valve is leaky. How can I remedy this?

Correct installation requires an angle valve with an appropriate contact surface for the seal. Angle valves that are conical in this area must be replaced. Secondly, the non-return valve cartridge must be screwed on tightly using an 8 Nm tightening torque. For more information, please refer to the enclosed installation manual.

Why is the electronic mixer buzzing or whistling in waiting position?

The non-return valves which are located in flow direction after the connection hoses are damaged and overflowing. The non-return valves must be tested and if necessary replaced. You will find the appropriate spare parts number in the relevant installation manual.

Electronic mixer: How can I use specific functions such as continuous flushing for thermal disinfection, the hygiene function or adjustment to the sensor range?
The various options are described in the installation manual, which is enclosed with the product or can be downloaded from the electronic spare parts catalogue.
Electronic mixer: How can I activate the mixer cleaning mode without triggering the sensor so that the wash basin can be cleaned, for example?
Activation of the cleaning mode is described in the installation manual, which is enclosed with the product or can be downloaded from the electronic spare parts catalogue.
Angle valves with fine filters are included with electronic basin mixers. Do these need to be installed as well?

The included angle valves must be installed in order to prevent incoming dirt from the supply network. Incoming dirt can impair the function and/or result in damage to the mixer's functional components. Damage resulting from this is not covered by our warranty!

How do I remove a cartridge?

Detailed installation/service instructions are supplied with the spare part and can also be accessed in the spare parts catalogue.

The Installation process is demonstrated in this video.

The pivot shaft of the kitchen mixer is leaky. What could be the cause of this?

The mixer's pivot shaft seals are soiled or damaged. The necessary assembly steps for replacing the seals can be found in the appropriate installation manual for the spare part. Make sure that the lip seals of the seal set are not too heavily greased.

I only get a low water flow from the kitchen mixer with pull-out shower / pull-out spout. What can I do?

Between the pull-out hose and pull-out shower there is a little filter screen, pushed into the pull-out hose connection fitting. Remove this using a sharp object, clean it and put it back in.

Kitchen mixer: The two jet types converge on the pull-out shower. How can I solve this problem?

Replace the hand shower head. This cannot be repaired by customers.
You can get the spare part hand shower head under item number 3589380X via your specialist bathroom retailer.

Kitchen mixer: Time and again there is slight leakage of water or blistering around the handle lever of the AX Starck kitchen mixer 10820XX0. How can I remedy this?
It's quite likely that this is merely water which collects around the handle lever when the mixer is operated with wet hands. This expands and appears as blistering, particularly when drawing hot water. Remove the excess water from the gap, ideally using a cotton cloth.
The swivel spout on the kitchen mixer leaks. What can I do?

If water leaks in the lower region once the mixer is opened, the seals must be replaced in order to properly seal the swivel spout. Follow the instructions in the particular installation manual supplied for your model when replacing the seals. You can also call these up in the spare parts catalogue.

How do you move the Variarc sink unit mixer with pull-out shower when you need to open the window?

Hold the base body of the mixer (NB: not the spout!), pull it upwards, and lay the mixer down sideways on the worktop (on a cloth or similar).

How does the HG PuraVida 15805XX0 electronic kitchen mixer work?

This video demonstrates how the mixer works.

Mixer ball technology: When servicing the mixer ball system, does the control ball need to be changed as well?
It is not necessary to change the stainless steel control ball. Any deposits can be removed from the ball easily, e.g. using a plastic cleaning fleece.
How can I service a mixer with mixer ball technology?

The different ways of dismantling the individual mixers are indicated in the corresponding installation manual for the spare part.
ATTENTION:  The service grommets are installed WITHOUT springs.

How can I clean the grommet seat or seal off the old mixers with mixer ball technology?

Use synthetic fleece to clean the grommet seats to avoid surface damage. Instead of standard springs and grommets, please only use the service grommet which is included with each service set No. 13952000.

Why does the shower hose not slide well in the Secuflex?

In most cases, lack of movement in the Secuflex hose is due to dirt. We recommend completely dismantling the Secuflex from above and cleaning the inner hose and protective hose. Rub the inner hose with a silicone cloth and pull the cloth several times through the protective hose. Another option to ensure functional ease of movement is to spray the shower hose with silicone spray No. 97864000. The silicone film minimises friction and prevents deposits.

Where must the water connection be for the Secuflex bath tub rim set?

The water connection is positioned according to the specifications in the Secuflex installation Manual, depending on the height of the bath tub and the Position of the Secubox. When installing please ensure that when it comes to servicing, the entire hose System can be pulled out through the hose duct and replaced at any time.

Can I convert older concealed mixers to a new design?

There are several options for converting older concealed mixers to a new design. For example, concealed shower mixers can be fitted with a modern ceramic mixer system using the conversion kit 96384000. A contemporary handle can then be installed on the mixer in accordance with the design. You can find more information, with the appropriate item numbers, in our electronic spare parts catalogue

Can the hot water temperature be limited on Hansgrohe mixers?

The maximum hot water temperature can be limited on Hansgrohe mixers with ceramic cartridge M1/M2/M3 (not on joystick cartridges) and on all thermostats. You will find the precise procedure in the relevant installation manual.

Can I manipulate the exit angle of a Hansgrohe basin mixer's water jet?

Hansgrohe offers the option of a swivelling standard aerator (item no.: 95400000) with M24x1 outer thread. With this, the water jet can be adjusted by approx. 8° all around. This video demonstrates how to replace the existing aerator with this one and how it works.

Is there a shaft extension for a basin mixer?

On basin mixers with a threaded shaft with a 32 mm diameter, the shaft can be extended by 35 mm with a shaft extension (item No: 13898000).
Mixers are therefore installable in plate thicknesses of up to 70 mm.
Alternatively, the installation surface below can be lowered (min. 55 mm) – observe bearing capacity/tensile strength!
On basin mixers with a stud fixture, the fixture can be extended using a conventional threaded rod M8.

What should be done if water is leaking at the diverter on my concealed mixer?

Clean the pull rod and the O-ring of the diverter and grease it with silicone grease.
The silicone grease promotes the sliding behaviour of the O-ring and also gives extra sealing.

Showers, shower supports and shower sets

Can another slide be used on the Axor Starck wall bar?

Yes, the Unica´D wall rod slide No. 96190000 is compatible.

What option is available to secure/stabilise a long shower arm better?

An additional mounting plate is supplied with each G1/2 and G3/4 shower arm for better installation.

How do I install a wall bar in a corner?

To save space, the wall bar can also be positioned in a corner. The installation process is demonstrated in this YouTube video.

The tiles have been cut out larger than the wall flanges. What can I do?

If the tile fitter has allowed for too much room around the connections for the bath filler, overhead or side showers, the universal wall flange item No. 06200000 can be used. The universal wall flange has a plastic insert for supporting heavy overhead showers and can be used for DN15 and DN20.
It has a diameter of 75 mm.

Tile compensation: Why is the tile compensation disk enclosed with a shower set made of light grey plastic and not chrome-plated?
The tile compensation disk made of light grey plastic looks good on different materials. However, it is only required in very few installation scenarios and in most cases is disposed of by the customer. Hansgrohe is committed to doing away with any unnecessary finishing treatment with chrome, even during the product creation phase, thereby protecting the environment. If you require a chrome-plated compensation disk, you can order this as a spare part. You will find the relevant article number in the installation manual or the spare parts catalogue.
Tile compensation: What is the purpose of the longish plastic disk that is included in the shower sets?
Not all bathrooms are fully tiled. As a result, in some cases it is necessary to offset the tile thickness. For bathrooms that are not fully tiled, the tile thickness can be offset with the tile compensation disk. The disk can be stacked if necessary.
Where should I install the holder for the hand shower for the bath tub?

The hand shower should be installed so that it can be reached without any problem. You should be able to wash your hair while sitting, without having to hold the hand shower.

What should be done if water is leaking at the air intake nozzles on the Raindance Rainmaker?

The jet disc or the boreholes in the air intake nozzles are limescaled/soiled. Please rub the jets (QuickClean) with a cloth and then unscrew the air nozzles (allen key 6 mm width A/F). Clean and descale these and screw in the air nozzles again gently (do not tighten hard).

What installation is required to connect a Raindance Rainmaker?

Different versions can be used to install a Raindance Rainmaker. For more information on installation, please refer to the corresponding installation manuals for the Rainmaker square, Rainmaker round and iBox universal products.

What can be done if the connection hoses to the Raindance Rainmaker are too short?

Pressure hose No. 94174000 (600 mm) can be used as an extension.

Can the Raindance Royale overhead shower be connected to a single lever mixer?

The Raindance Royale overhead shower must be connected to a highflow thermostat, an iBox universal basics set (item number 01800180) and e.g. pre-fab set 15715000.

Which wall connection is required for the Raindance Royale overhead shower?

A DN 20 (G3/4) internal thread is required for connection. Attention: For light-weight constructions/stud walls, a wall or ceiling reinforcement must provided in the area of the overhead shower connection! The Raindance Royale overhead shower including shower arm weighs about 9 kg.

Can the riser pipe for the showerpipes be shortened?

Depending on the model, riser pipes can be adapted on request to suit the room layout and shortened if necessary. In principle, round riser pipes can be shortened. Rectangular riser pipes come in various lengths. Please refer to the installation manual supplied for more information.

How should a sealing screen be installed between shower hose and hand shower?

Sealing screens, which are included with each hand shower, cannot be replaced by normal seals. Otherwise dirt, which is filtered out in the filter screen, gets washed into the mechanics of the shower. This leads to the QuickClean cleaning function breaking down or the sprays becoming clogged.

Can the replacement Unica`D slide be installed even if you have an older wall bar?

Generally speaking, the replacement slide can be used with all Unica`D wall bars.

What installation is required to connect a Raindance Rainfall?

There are different options for installing a Raindance Rainfall. For more information on installation, please refer to the corresponding installation manuals for the Rainmaker Rainfall and iBox universal products.

Steam cabins

How much fragrance is used in a steam bath?

The automatic fragrance dosage system consumes about 340 ml of fragrance every 30 minutes.
The following fragrances are currently available for the Pharo range:
eucalyptus, eucamint, lemon and pine.

Is it possible to retrofit a shelf or other fittings in an acrylic steam cabin?

It is not possible to attach fittings after installation!
On showers with a pre-existing Unica wall rod, a Cassetta soap dish can be installed or two soap dishes can also be attached.

Shower systems

Why does the light on the shower panel no longer work manually using the pushbutton?

This could have two reasons:
1. The pipeline pressure (at least 0.8 bar flow pressure) is too low so the button does not respond.
2. Another transformer has been used (one not included in the scope of delivery).

Why does the keypad of the shower panel not light up correctly and it is not possible to adjust the motor?

If this error occurs with a newly installed shower panel, then it is highly probable that an incorrect transformer (electronic transformer) has been installed.
Remedy: Exchange the installed one with the originally supplied transformer.

Why can the Lift shower panel not be raised or only be raised with difficulty?

Please test for the following:
- The cable ties on the connection hoses have not be removed
- The roller guide is bent or the glide rollers have not be adjusted
- There are faulty connections

I would like to install a shower pipe, but the bathroom is not fully tiled. Is there a solution for this?

You can get a tile compensation shim for shower pipes, and this gives 7 mm adjustment. You can get the appropriate item number from the relevant installation manual.

A height adjustable slide is required for the Axor shower pipe. Is that possible?

Yes, the diameter of the riser pipe is 22 mm.
This means the Unica`S slide No. 97651000 or the Unica`S slide No. 28672000 will fit.
Slide No. 96505xxx can be used for special surfaces.


How long is the guarantee period for Hansgrohe products?

In principle, the buyer of a product has a guarantee claim against the seller for a certain duration. Since Hansgrohe distributes its products to its customers exclusively via the 3-stage distribution channel, i.e. via wholesale trade and specialist dealership, this means the customer has a guarantee claim primarily against the specialist dealership, i.e. against the seller, but not against the manufacturer. In case of any guarantee claims, please contact the outlet where you purchased your product.

Does Hansgrohe offer a guarantee voluntarily in addition to the legal guarantee?

Top quality is a fundamental component of Hansgrohe's company philosophy. We therefore offer consumers a voluntary manufacturer's guarantee of five years on our products. You can find the prerequisites and details of this guarantee in the Conditions of Guarantee.

Does the manufacturer's guarantee for the product become null and void if service parts are replaced?
One of the prerequisites for the retention of our Conditions of Guarantee is professional installation of the product. When replacing spare parts, this professional handling is described in the service instructions. You will find further information about this in our Conditions of Guarantee.

Base units

Sealing: Do I need to seal wall penetrations and joints?
Defective joint sealing or even the absence of such on installation access holes can cause significant damage to the structural shell due to the penetration of water. Joints on concealed mixers and on pipe penetrations must be properly sealed, permanently elastic, in accordance with DIN 18195/Part 5 (Water-proofing against non-pressing water on floors and in wet areas; design and execution), e.g. with sealing cuffs and through the use of appropriate sanitary silicone. Sanitary silicone must also be applied to screw holes to protect them against moisture penetration. You will find more information about this in the installation manual included with the product.
Can the iBox also be installed horizontally into the edge of the tiles?

Yes, the iBox universal can be installed into the edge of the tiles. If the bath tub is filled via the overflow, installation must be implemented in accordance with EN 1717. Thereafter horizontal installation is not permitted. Watch a video on YouTube to see the step-by-step installation of the iBox universal.

iBox universal: Why are the carrier screws for the sub plate of the iBox universal made of plastic and not metal?
The carrier screws are made of plastic on purpose due to safety-relevant aspects. The most important thing to ensure with regard to the iBox is that the connection to the masonry is absolutely waterproof. This is why the fastening points in the iBox for the sub plate are furnished with moulded-in brass bushings. If you were to screw metal screws of the wall flange sub plate into these brass bushings, the brass bushing could be pulled out if overtightened, or the iBox broken in the wall. It is absolutely essential to prevent this from happening. Consequently, these plastic screws are inserted as a predetermined breaking point. The plumber will realise that plastic screws are being used and will not overtighten the screws. Which is what we want. If a component is going to break due to overtightening, then it will be the plastic screw, which can easily be replaced. No permanent damage can be caused to the iBox. It is important to shorten the plastic screws to the required size (span length+10mm) prior to screwing them in, using pliers for example. If the plastic screws are completely screwed in, although not required, this can lead to problems when unscrewing the screw during a subsequent service.
How can the iBox universal be shut off during the roughing-in phase when connected with the Exafill?

A small red plug is inserted at the front of the flushing block to close the outlet to the Exafill. Insert the plug into the Exafill outlet in the base unit. For more information, please refer to the iBox universal installation manual.

How are the pipelines flushed on the iBox universal?

Flush the entire installation according to DIN EN 806-4. The arrows on the flushing block show which inlet is connected with which outlet pipe, e.g. cold water with outlet 1 (bottom) and hot water with outlet 2 (top). If only one outlet is required, turn the flushing block by 90° after the first flush.

Click here for the full installation video for the iBox universal.

How is the iBox universal connected (cold/hot water)?

Position the iBox with the outlets horizontal and vertical. Make sure that the sticker with the min/max labelling is upright. It is important that cold water is connected on the right and hot water is connected on the left. Also make sure that the lower outlet is always connected first.

iBox universal: What is the purpose of the four noses on the front of the iBox universal?
The four noses enable a spirit level to be placed upon the iBox so that the product can be 100% aligned.

Cleaning and care

How do I clean and remove limescale from my Hansgrohe products correctly?

We have compiled information on maintaining the sheen and function of Hansgrohe products for the long term: To the cleaning recommendations.


Can you put a complete overhead shower in the dishwasher?

The plastic parts of the shower are not designed for the high temperatures in the dishwasher's drying program. Only the metal spray disc is suitable for this. The precise procedure is illustrated in the enclosed installation manual.

Thermostats and valves

The 2-hole thermostat buzzes and does not maintain the temperature. Why is that?

The non-return valve under the control unit is not installed or is soiled.
Please install the non-return valve or clean it.

Is there a mounting base for the 2-hole bath tub thermostat?

No, there is no installation plate or mounting base for installing on a tile edge.
It is better to place the thermostat directly into the bath tub rim.
If this is not possible for technical reasons, the thermostat can be installed e.g. into a marble plate. It is not necessary to access the base unit under the bath tub rim for servicing.

The handle of the shut-off/diverter valve on the thermostat is stiff. How can I solve this problem?

Stiff movement could be due to a number of causes. For example, deposits on the sealing surfaces can cause stiff movement. Please replace the component in accordance with the enclosed installation manual. You can find more information in our electronic spare parts catalogue.

Reversed connections: Is there an exposed thermostat or a special control unit for this?

For reversed connections, you have the option of using a mixing valve, article number 92373000, instead of the thermostatic cartridge 98282000. The product then functions similar to a single lever mixer.

Is there a concealed thermostat or a special control unit for reversed connections?

The function block can be easily rotated by 180° on a concealed thermostat from Hansgrohe. You do not require any additional components, except if using the thermostat with shut-off and change-over. In this case, you require a differently printed wall flange. Simply dismantle the visible parts during conversion and release the four mounting screws on the function block after shutting off the water. Rotate the function block by 180° and reinstall it.

When installing the thermostat the outlet temperature is no longer correct. What can I do?

Correction is necessary if the temperature measuring at the tap point differs from the temperature set on the thermostat. Take note of the following: Turn the scale handle until water is discharged at the tap point at the desired temperature (38°C). Release the handle screw, pull the handle back and turn to 38°C. Then replace the handle and tighten the handle screw.

The button for the thermostat handle safety lock is jammed. How can I remedy this?

It's likely that the button is merely calcified or the spring is defective. Clean the spring and button and grease them lightly. If necessary, the components must be replaced. You will find the spare parts numbers in the installation manual or in the online spare parts catalogue.

What steps are required to install an Ecostat Select showerpipe?

In this video we show you the process for installing an Ecostat Select showerpipe.

Why does the handle jam after assembling the pre-fab set?

The spindle adapter (plastic sleeve with the smaller diameter) is too long. Saw off the spindle adapter to the length as stated in the installation manual.

Which control unit do I need as a spare part for the highflow concealed thermostats of the iBox universal?

Control unit No. 96633000 is required as spare part.

Is a pipe interrupter required for a thermostat if the bath tub is filled via the overflow?

If the bath tub is filled via the waste set overflow, pursuant to EN 1717 a pipe interrupter must be installed at an installation height of 150 mm above the highest possible dirty water level.

How can the installed non-return valves be dismantled on thermostat No. 13550180?

Briefly allow the water to flow. The non-return valves then slip out.
If the mixer is not installed directly near the shut-off device, two people may be required for this job.

Following installation of the ShowerSelect or ShowerTablet, the button cannot be actuated or is not working.

When installing the mixer, the green retaining bracket was not removed from the valve. Dismantle the visible components and remove the bracket.

The seal between button and wall flange may not have been greased. Lightly grease the seal using silicone grease.

Does shutting down the ShowerSelect products cause high pressure shocks in the pipe?

Shutdown can cause pressure shocks in the pipe, similar to any single lever mixer. However, the resulting pressure shocks comply with the permissible values of EN 15091.

ShowerSelect: Can I adjust the flow rate on these products?

The water volume cannot be adjusted on ShowerSelect products. On the new Raindance Select hand showers you can choose between a soft or hard jet. A large number of significantly water-saving EcoSmart hand showers are available. When it comes to overhead showers, the key focus is generally on guaranteeing a pleasurable shower experience. The flow performance of the overhead showers is tailored accordingly.

Thermostatic mixer: Following installation, only cold or hot water is flowing out. What could be the cause of this?

One of the possible causes could be reversed connections for hot or cold water. The connection for hot water must be implemented from the left, and the connection for cold water from the right. On the iBox universal this can be checked easily with a central thermostat, for example. Function is guaranteed by rotating the function block 180°, reversed connections notwithstanding. In combination with exposed mixers, you have the option of using a mixing valve, article number 92373000, instead of the thermostatic cartridge 98282000. The product then functions similar to a single lever mixer.

Why can't the rotary handle of a concealed mixer be operated correctly after an installation?

Check the length of the shortened spindle adapter. This might be cut too short or installed incorrectly. You will find the spare parts number for the appropriate threaded sleeve set in the enclosed installation manual if necessary.

The replacement handle for my concealed thermostat mixer is missing the mounting screw. How can I install the handle properly?

Since 2012, thermostat handles have been snap-on. The mounting screw is no longer necessary. Snap-on handles are simply clipped on and can be removed with a powerful tug whenever required.


The hydro nozzles in the whirlpool do not work, why?

Either the water level in the bath tub is too low, or the sensor sensitivity must be readjusted.

Whirlpool 300 and 700: Why do the air nozzles whistle after a longer period of operation or during operation pauses when dry-blowing the air pipes?

The membranes of the air nozzles can become stuck with deposits and lime-scale.
Remedy: Remove the air nozzle (only pushed on) and rub the red membrane located under the air nozzle with silicone grease or silicone oil.
Before re-installing the air nozzles, place the chrome parts in hot water (for about 5 minutes), and then replace the red membranes and reassemble the air nozzles while still warm.

The hydrosystem on the whirlpool does not work at full power any more, why?

Probably the suction lock for the hydrosystem (non-return valve) is not leak-tight, meaning that the "wrong air" is being sucked in the entire time.
