Procedure for descaling a Senseo coffee maker

Descaling your coffee maker is part of routine maintenance: Philips recommends descaling every three months. This maintains the quality of the coffee, reduces the risk of breakdowns and extends the life of your coffee machine.

Repeat the following procedure twice:

  1. pour a litre of half water/half white vinegar mixture or a litre of water and a dose of Senseo descaler into the tank;
  2. insert a used pod into the double pod holder;
  3. turn on the coffee maker;
  4. repeat a two-cup cycle until the tank is empty.

Then rinse your coffee maker twice with clean water by filling your tank twice.

Carefully wash all the removable parts of the machine: water tank, pod holder, lid, coffee collector and coffee spout.

Test the boiler of your Senseo coffee maker

To access the boiler of your Senseo:

  1. Unplug your coffee maker and remove the water tank;
  2. Remove the cup holder and the coffee spout;
  3. Unclip the plastic cover at the back of the machine with a flat screwdriver to gain access to the boiler;
  4. Disconnect the electrical cables and hoses to remove the boiler from its location.

Test the resistance with an ohmmeter: place the points on the terminals of the resistance, the value displayed should be around 35 ohms. If not, you need to replace the boiler of your Senseo coffee maker.

Test the thermostat of your Senseo coffee machine

This thermal sensor, also called Klixon or thermostat, is fixed on the body of the boiler: a small black plastic cylinder with two electrical lugs.

Test the continuity of the thermostat: set your multimeter to continuity mode and position the pins on each of the thermostat connectors. If you do not hear a beep, change the thermostat.
