Cleaning and descaling:




The cleaning warning light comes on after 350 coffees (or espressos).
The descaling light comes on after:
 1200 cycles on water hardness setting 0
 1000 cycles on water hardness setting 1

800 cycles on water hardness setting 2

600 cycles on water hardness setting 3

300 cycles on water hardness setting 4
Where:
 1 coffee (or espresso) = 1 cycle
 1 " steam " function = 40 cycles
 1 " hot water " function = 1 cycle
The number of cycles is doubled when a Claris cartridge is used (programming in the display

Ejection faults:

Description: the switch does not detect the release of the ejector rod This creates repeated
auto-tests faults and 12 and 13 registered in the after service app (SAV).
Detection: during coffee making, when ejecting the grounds cake, the pin does not shift
sufficiently to release the rod and the jack switch does not switch when the jacks is lifted.
Check: place a lamp wired to multimeter clamps on the jack switch. Start making a coffee, the
lamp should light from the start. When the jack moves back up the lamp should go out for a
moment and then light again. If this does not happen, there is an ejector fault.
