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 First check if the frame is too thin.
2 The third passage of the valve is obstructed,
therefore the final suction is less than it
should be.
3
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.
DANGER
Before proceeding with the operations
described in the chapter make sure that the
machine is turned off and unplugged from the
mains. Discharge any residual pressure pre-
sent in the heater.
