Descalling (SIC) is necessary to keep your espresso machine running efficiently. 

• As a result descaling of your espresso machine should be done fairly frequently 
with citric or tartaric acid. 
• Use caution when descaling your espresso machine as the acid substance within the descaling powder may damage countertops or any other surface it comes in contact with.

However, we would advise you to use the reference solution as W F054 that is available from Krups. Descaling depends on the hardness of the water, but also on the frequency of use.

To descale, follow the following method:

Setting up for descaling

  1. Dissolve half a packet of KRUPS descaling solution in 500 ml of lukewarm water and pour the whole batch into the empty water container.
  2. Insert empty capsule holder into machine and place jug underneath.

Descaling

  1. Turn the machine on and wait 5 seconds.
  2. Switch the lever to the hot position until half of the water has passed through the machine.
  3. Switch the lever to the middle position and leave for 5 minutes.
  4. Switch the lever to the cold position until the remainder of the water has passed through the machine.
  5. Switch the lever to the middle position and leave for 5 minutes.

Rinsing

  1. Rinse and fill water tank with 1 litre of fresh water and replace jug underneath.
  2. Switch the lever to the hot position until half of the water has passed through the machine (half a litre).
  3. Switch the lever to the cold position until the remainder of the water has passed through the machine.
  4. Switch the lever to the middle position and turn your machine off.
  5. Wipe your machine with a dry clean cloth.

    The warranty does not include espresso machines that do not function, or do not function properly, because descaling has not been carried out.
