How to flush my Quooker tank? Troubleshooting

Sometimes, it might be useful to flush your Quooker tank. Especially after your Quooker hasn't been used for a long time, when you are having troubles with splattering boiling water, flushing your tank is advisable, in case you can see black spots of active charcoal in your water...


Instructions on how to do so can be found below:

1. Activate the boiling water on your tap, and let it run until no more water is coming out (you are now emptying your Quooker tank). With a PRO3 this will take roughly 3 minutes, while for a PRO7 or COMBI tank this will take 7 minutes.

2. Once the water has stopped, turn back your push-and-turn button on your tap. A solid red light should appear on your tap and tank. This is to indicate that the water inside the Quooker tank is being warmed up to boiling temperature.

3. Wait for about 10-20 minutes, until the solid red light goes off. The tap should not have any light right now, while the tank will show a slow fading pulse, which we refer to as the "heartbeat" of the Quooker.

4. Try to activate the boiling water at your tap. Boiling water should come out.

Sometimes it might be useful to flush your tank twice, directly after each other.


After flushing your Quooker tank (twice), you can be sure that your Quooker tank is filled with fresh boiling water again. The issue you we experiencing before should now be solved.

In case your problem isn't solved, kindly contact the Quooker Service Team at When contacting them, please inform them about the fact that your Quooker tank has been flushed and share a video of the problem you are experiencing.
