Krups EC422 Mode D'emploi page 10

 When to descale
- When descaling is necessary, the CLEAN icon will appear on screen.
- However, the descaling frequency depends on the hardness of the water and the number of brew cycles.
It may be necessary to descale your coffee machine if you notice the following signs, even if the CLEAN
message does not appear on the screen : longer cycle time, excessive steaming, more noise at the end of
the cycle, stopping mid-cycle ; this means that your machine needs to be descaled.
- Descaling should be done about once a month, depending on the hardness of the water.
How to descale your KRUPS coffee maker
 Remove the filter cartridge. Fig. 28*.
 Use the KRUPS descaling solution
temperature (or 1.5 oz of citric acid diluted in 17 fl. oz) until the crystals have completely dissolved. Fig. 29.
 Pour the solution into the water tank (without coffee). Fig. 30.
 Press the CLEAN button (o) Fig. 31 and then the BREW/control button (k) to start the descaling cycle.
 The cycle lasts for 30 min.
 Please wait until the end of the cycle.
 If the water tank is not empty, please launch another descaling cycle by pressing CLEAN button (o).
 To rinse the machine, run 2 full 12 cups cycles with water but without coffee. Fig. 32.
 Repeat the operation if needed.
 Replace the filter cartridge. Fig. 35* and 36*.
 The warranty does not cover coffee makers that do not work, or do so poorly, due to lack of
descaling.
DUO FILTER CARTRIDGE*
 Your coffee maker filters water using a DuoFilter: a double action filter – reduces chlorine and scaling –
formulated with active plant ingredients. This Duo Filter allows you to enjoy the most delicate aromas of
your coffee and reduces the need to descale.
 In its upper part, the filter cartridge support is equipped with an indicator for replacement of the cartridge.
 Select the number of the month when you replaced the filter. It will display the month when you should
change your filter according to water hardness. Fig. 34*.
 To change the filter, remove the DuoFilter from the tank. Fig. 33*.
 Open it by unlatching and opening the lower part and replacing it. Fig. 35*.
IMPORTANT :
The DuoFilter filter must only be used with water.
Your coffee maker operates even if the water filter is not installed.
If you have not used your coffee machine for over a month, rinse the DuoFilter filter under
running water.
It is recommended not to leave the DuoFilter water filter in place for over 5 months.
The DuoFilter may need to be replaced if water flow is slow, machine releases excessive steam,
or machine makes loud noises when brewing.
