The tank seat allows the water to pass from the tank to the pump and to filter it slightly, retaining the calcareous impurities ensuring the quality of the water. Over time, seals or pipes deteriorate and can cause leaks.

Your tank seat may be damaged if:

  • Your Dolce Gusto coffee maker is leaking from the reservoir or under the machine.
  • Your coffee no longer flows or with a reduced flow.
  • Your coffee maker flashes.

The tank seat is located under the water tank and is connected to the pump.

The tank seat in a Dolce Gusto coffee maker is an essential part that holds the water tank in place. Over time, this seat may suffer from wear and tear or even break, affecting the machine’s performance. If this happens, replacing the tank seat can restore the coffee maker to its full functionality. Here’s a step-by-step guide on how to change the tank seat of a Dolce Gusto coffee maker.
