4.2 cOFFee valve
It is a solenoid valve that is normally closed and
opens when it received a command to dispense
coffee.
By closing the decompression removes any
excess water from the filter holder.
TYPICAL PROBLEMS
Check the operation of the valve, if the unit con-
tinues to drip continuously or if the coffee cap-
sule is too wet.
Possible causes:
1 The third passage of the valve is obstructed,
therefore the final suction is less than it
should be.
2 Shower and pavilion are blocked because of
poor machine cleaning.
HOW TO REPLACE THE COFFEE VALVE:
To remove the coffee valve proceed as follows:
1 Remove the right, side panel and the front
one, as explained in Chapter 3.
2 Disconnect power connections.
3 Disconnect the Teflon tube by removing the
cable holder “A” using the pliers.

ent in the heater .
