Please note: it may still be very hot!
For more thorough cleaning, the nozzle may be taken off (10):
•Unscrew the tip (g1), if necessary using a coin.

•If need be, unblock the tip (g1) using a fine needle.
Descaling
It is vital that you descale your espresso machine in order to guarantee its continued operation.
•Descale your espresso at regular intervals using citric or tartaric acid.
We do, however, advise you to use the Krups descaling accessory, reference 054, which is available from approved Krups service centers. This accessory includes, in addition to two doses of descaler, a water hardness test strip to evaluate the frequency of descaling for your appliance in normal use. The amount of scaling depends on the hardness of the water, but also on how often it is used. The frequency of descaling indicated by accessory 054 is thus given by way of indication only.
You must never, under any circumstances, use classic sulfuric acid or other products
containing this acid as there is a risk of damaging the appliance. Carefully check the composition of the descaling products you intend to use.
- Then use the following method:
•Unscrew the grid of the percolation head and clean it (9).
•Dissolve 2 tablespoons of descaler or one packet of accessory 054 in half a liter (16 oz) of lukewarm water and pour the mixture into the empty water tank.
•Set the «on/off» switch (h). The indicator light (h1) comes on.
Once the appliance reaches the appropriate temperature, the temperature control indicator light (c) comes on.
•Place a container under the percolation head. Run through about 1/3 of the mixture, setting the function selector (b) to the position « ».
•Set the «on/off» switch (h). The indicator light (h1) comes off and wait 10 to 15 minutes to allow the descaler to take effect.
•Then set the «on/off» switch (h). The indicator light (h1) comes on.
•With the function selector (b) in the position « », allow the remainder of the mixture to run into the container placed under the percolation head.
•Then reset the function selector (b) to O.
•Run two tanks of fresh water through to rinse the percolation head. To do this:
. fill the tank
. place a container under the percolation head, set the function selector (b) to « » and allow the content of the tank to run through.
. then set the function selector (b) to O.
•Set the «on/off» switch (h). The indicator light (h1) comes off
.replace the grid on the head of the appliance (see paragraph «Maintenance») (9).
Notes:
In the case of serious scaling, soak the grid of the percolation head for 5 minutes in 1/3 of the mixture obtained during the first run- through.
If necessary, this operation can also be performed with the steam nozzle:
