If the Quooker system light flashes rapidly, this indicates a malfunction. The advice is to reset the reservoir. 

The Quooker tank can be reset by following these steps:
 1. Turn off the reservoir by pressing the red 'Q' on top of the reservoir.
 2. Pull the plug out of the socket.
 3. Remove the plug from the red cap at the back.
 After 10 seconds, put the plug back onto the cap and put the other plug back into the socket. Press the red 'Q' to turn the reservoir back on.
 4. When the light is on continuously, check whether boiling water comes out of the tap after 25 minutes.

Should the malfunction still occur after a third attempt, please contact our service department. Make sure you have the serial number of the reservoir and the tap at hand and look carefully at the frequency of the flashing light.

If there is not longer boiling water coming out of the Quooker tap, this can have several causes: 

 1. The supply of boiling water has been used up. With a PRO3 reservoir, there is a 3-litre supply and the reservoir is fully reheated within 10 minutes. With a COMBI(+) reservoir, there is a supply of 7 litres of boiling water, this reservoir is fully reheated within 20 minutes. 
 2. The reservoir has been switched off. With the reservoir switched on, you will see a red light pulsing under the Q on the lid. You switch on the reservoir by pressing the red Q on top of the reservoir. 
 3. The tap plug is not connected to the reservoir. First switch off the Quooker by pressing the large Q. Check that the tap plug is connected to the reservoir. You can find this plug at the back of the red cap. Then turn the reservoir back on by pressing the large Q.
 4. The reservoir is not receiving power. Check the reservoir power supply: Check that the plug is properly plugged into the socket and that the socket works by briefly plugging another device into it. Finally, check the fuse in the group box.
 5. Maintenance is required on the reservoir. See our maintenance page for more information. 

Should the cause lie elsewhere, please contact our service department.

On top of the Quooker tank is the on/off switch that houses a red LED light. This light will pulse (slowly on and off) when the system is in standby mode. This means that your Quooker system is ready to use. We call this pulsating light the ""heartbeat"" of the Quooker.

When using the Quooker tap, this light will be on continuously indicating the system is heating the water.

Does the red LED light keep flashing rapidly and frequently (2x or 4x with a short pause in between)? If so, this could indicate a possible malfunction. If so, please contact our service department.

Reduced water flow may mean maintenance is needed. The problem may already be remedied by descaling the tap filter and the aerator. On average, this has to be done twice a year. Click here for an explanation on descaling of the aerator. 

Should the cause lie elsewhere, please contact our service department.

Open the tap (lever up) and then spray the glass cleaner (do not spray more than 2x) into the opening. Then bring the lever down with light pressure and let it go up and down from left to right. It is important not to use too much glass cleaner.

We strongly discourage the use of other cleaning agents. These can affect the coating of parts and the grease in the tap, which ensures that all parts move smoothly.

Should the cause lie elsewhere, please contact our service department.

Should your Quooker system unexpectedly leak somewhere, we advise you to turn off the Quooker tank using the on/off button. Then drain the boiling water from the tank by opening the boiling-water tap until cold water comes out (cool it with some cold water to avoid damaging your sink). Close the inlet combination valve after this. The inlet combination valve is the part with the grey funnel and is mounted on the cold water pipe (see image).

If the mixer tap only gives lukewarm water, this could have several causes.

 - With a COMBI tank, this can be caused by the boiling water supply being used up. This reservoir has a supply of 7 litres of boiling water and is fully reheated within 20 minutes. 
 - The reservoir has been switched off. You switch on the reservoir by pressing the red Q on top of the reservoir. 
 - The temperature setting on the mixing valve is incorrect. On the mixing valve there is a temperature setting knob that you can turn to reset the temperature. Your mixing valve may also need to be replaced in its entirety.
 - Maintenance is required on the reservoir. See our maintenance page for more information. 

Should the cause lie elsewhere, please contact our service department.

With a Quooker Flex tap, the flexible pull out hose may not hang properly in the tap. Pull the hose down as far as possible and let it spring back gently. Then operate the Quooker again using the press-press-turn method.

Should the cause lie elsewhere, please contact our service department.

One of the safety precautions of the Quooker tap is that the boiling water spray is not massive. This makes the risk of burns very low, as you can withdraw your hand in time. We recommend keeping your glass or pan as close as possible to the spout of the tap when you tap boiling water. 

Does your tap keep splashing? Then it may help to descale your tap filter (the aerator). Depending on the hardness of the water in your area, we recommend checking this every 6 months. Watch our instructional video for more information.

Should the above not improve the situation or if you believe the tap is still splashing too much, please contact our service department.

This could be due to the coupling piece hanging from the tap. The connector of the Quooker Flex tap must be able to move freely. When not pulled out, the hose hangs about 40 cm below the work surface. Keep this in mind when installing. If the connector has too little room to move, the pull out hose cannot be fully extended.

If the bubbling or chilled water has insufficient passage, you could follow the following steps to improve the passage:

 - Models purchased before December 2021 have a filter in the CUBE as per standard. Check that the filter in the CUBE is properly pressed in. At the top of the CUBE, you can find the filter by opening the white hatch. Press the filter firmly until a click is clearly heard and close the hatch. 
 - Check that the CO₂ cylinder valve is properly open. 

Should the cause lie elsewhere, please contact our service department.
