1. Switch the Quooker off on top of the tank and unplug it from the power supply.

2. Find the thin black LED cable which runs from the tap to the top of the back of the tank. Unplug it from the tank. Wipe the tip of the cable with a clean, dry cloth. Plug it back into the tank.

3. If your tank’s serial number includes the letters VCD or VCW, there’ll be two ports the LED cable could go into. The spare one will be covered by a plastic cap. Take off the plastic cap and put the LED in this port. (If you have a Cold Water Filter or CUBE the spare port will be in use for this, so there’ll be two LED cables, not one. If that’s the case, swap the cables over so each one is now plugged into the other port.)

4. Plug the tank back into the electrical socket, and turn the socket on. But leave the Quooker tank off. (Q button on top of tank is the switch for the tank)

5. Run the boiling water tap for about three minutes to replenish all the water in the tank.

6. Leave the tank switched off for another 15 minutes. After that, turn it back on. You should see a solid red light on the tap and tank.

7. After about 10-20 minutes more, the light on the tank should slowly pulse like a heartbeat. The light on the tap light will go out. Once that’s happened, the Quooker’s boiling water tap is ready for use again.

If you try all these steps and you're still having problems, please contact our Service team. Use the Live Chat on our website, or log into your My Quooker account and fill in the service Contact Form.

The Flex hose runs through the spout of the tap and hangs down underneath the back of tap, attached to a counterweight.

If the hose won’t pull out or go all the way back in, it’s likely something is blocking the counterweight or snagging the end of the hose beneath the sink.

Look under the sink to check the weight and hose can move freely. This should solve the problem.

Check the tank is plugged in and turned on at the mains, then press the Q-shaped button on top of the tank to switch the tank on. 

If the light still doesn’t come on, unplug the Quooker and check the socket is working by trying a different appliance. 

If the socket is working, try replacing the Quooker plug’s 13-amp fuse and turning the Quooker on again by pressing the Q-shaped button.

If this still doesn’t work, please let our service team know. We’ll need your Quooker’s serial number, which is on a sticker near the top of the side of the tank. 

You can contact our Service team using the Live Chat on our website, or by logging into your My Quooker account and filling out a service Contact Form. We will then get back to you.

Please contact our service department making sure you have your Quooker’s serial number to hand. It’s on a sticker near the top of the side of the tank.

If you live in a hard water area, there's a chance limescale could have built up in the end of the tap causing the water to flow more slowly. Unscrew the nozzle and take out the ‘aerator’ from the tap end. Soak it in a small cup of white wine vinegar for one hour. Rinse off any limescale and put the tap back together.

If this hasn't helped, there might be limescale inside the tank. If that’s the case, it will need to be cleaned. 

We can arrange this for you. Just contact our Service team using the Live Chat on our website, or by logging into your My Quooker account and filling out a service Contact Form. We will then get back to you.

Alternatively, you can clean the tank yourself at home using our maintenance kit, which can be ordered here. Just enter your serial number to find the correct kit for your Quooker. 

If the light on top of the tank is solid red or pulsing, try turning the COMBI mixer valve towards the letter ‘W’. This should make the water warmer, up to a maximum of 65°C. (For help finding the COMBI mixer valve, see our COMBI installation guide.)

If the mixer valve is turned all the way to ‘W’ and you’re still not receiving hot water, double-check the tank is turned on. Make sure the tank is plugged in to the power socket and the socket is live. Press the Q-shaped button on top of the tank, the red light should come on.

If the tank’s light won’t come on, test the plug socket is working by trying a different appliance. If the power socket works, try replacing your Quooker’s 13-amp fuse.

If this still doesn’t work, please let our service team know. We’ll need your Quooker’s serial number, which is on a sticker near the top of the side of the tank.

Try to work out where the leak is coming from, then contact our Service team using the Live Chat on our website, or by logging into your My Quooker account and filling out a service Contact Form. We will then get back to you. 

If you need to shut off your Quooker’s water supply, press the Q-shaped button on top of the tank to turn the Quooker off. Next, run the Quooker’s boiling water tap until it runs cold (this could take a few minutes).

Then, find your Quooker’s shutoff valve. It’s a metal valve between the tank and cold-water supply. Turn the small grey lever, so it’s across the pipe. Your Quooker should now be isolated from the water supply.

Important: don't use the Quooker tap or turn on the tank while the water supply is shut off. Doing either of these could damage your Quooker.

When you first turn on the Quooker tank, a solid red light with an occasional flicker should appear on the tank and tap. This means the water in the tank is heating up.

Once the water’s fully heated, the light on the tap should go out, and the light on the tank should slowly pulse. This is the tank’s ‘heartbeat’. It means 100°C boiling water is ready to use.

If the light on the tap or tank starts flashing, please visit the self-service page on our website. 

The light flashes twice if there might be a fault, or when the tap has lost communication with the tank. Start by reconnecting the tap to the tank with these steps:

1. Make sure the tank is plugged in and the power is switched on.

2. Pull the tap’s thin black LED cable from out of the Quooker tank.

3. Turn off the power to the tank at the wall socket.

4. Reconnect the tap’s LED cable to the Quooker tank.

5. Turn the power back on. Do this by pressing the Q-shaped button on top of the tank (it might need a couple of presses). You should see a solid red light on the tank and the tap.

6. Push-push and turn the tap’s textured ring. Water should start to come out.

If you try all these steps and the tap light still keeps flashing, please contact our Service team. Use the Live Chat on our website, or log into your My Quooker account and fill in the service Contact Form.

The red light on top of your Quooker’s tank lets you know what your Quooker is doing.

If the red light is slowly pulsing, all is well. Your Quooker is simply at rest. Think of this red light as its heartbeat. (We actually call it the heartbeat light.)

From time to time, the tank needs to heat up. When this is happening, the red lights on the tank and the tap become solid. The more you use your Quooker, the more often the light will be solid.

A flashing red light on the tank means there’s probably a temporary fault. Most of these are easy to fix with a quick reset which you can do yourself at home. You can find instructions in our 'how do I reset my Quooker' FAQ.

If there’s no light at all, the power to the tank is probably turned off. Make sure the tank is plugged in, and try pressing the Q-shaped button on top of the tank to turn it back on. (It might need a couple of presses.)

If the power is on and there isn’t a light, check the power socket is working correctly by trying a different appliance. If the socket definitely works but there’s still no red light, please contact our Service team. Use the Live Chat on our website, or log into your My Quooker account and fill in the service Contact Form.

We’ve recently updated the design and name of our Cold Water Filter cartridge. It’s now designed to be compatible with our other Quooker accessories while reducing plastic usage and making the cartridge more sustainable, so it looks different from the old cartridge. 

AC stands for Activated Carbon and is the same filling as in the old cartridge. It may feel different to the old cartridge when screwing it in to the filter head, some free movement to it is normal.

If your system isn't registering the replacement cartridge, please follow the steps below.

1. While everything is switched on, remove the Cold Water Filter’s black power cable from where it is plugged into the back of the Quooker tank.

2. With the cable removed, turn off the power to the Quooker tank at the plug socket.

3. Re-connect the filter’s power cable to the Quooker tank.

4. Switch the power back on at the plug. Switch on the Quooker tank on by pressing the Q shaped button on the top of the tank (if it hasn’t come on by itself).

5. Press and hold the button on top of the filter head until you hear a double beep, this takes about 10 seconds.

6. The Cold Water Filter should now work.

If this doesn't work, please contact our service team. You can log into your My Quooker account and fill in the Contact Form, or speak to us through Live Chat on our website.

Sometimes an air bubble trapped in the system can cause a Quooker to drip.

Try running each tap for one minute. This should let any air bubbles escape. (Run each water source separately. For example: cold water; chilled water; hot water; then boiling.)

If your Quooker tap keeps dripping after this, please contact our service team. You can log into your My Quooker account and fill in the Contact Form, or speak to us through Live Chat on our website.

It's on a sticker near the top of the side of the tank.
