valve
The coffee valve “A” is situated underneath the
upper panel, on the left side, and regulates the
amount of water flowing inside the heater during
all phases of machine operation.
HOW TO REPLACE THE COFFEE VALVE
To remove the coffee valve, it is necessary to:
1 Disconnect power connections using twee-
zers.
WHEN TO INTERVENE
1 The system detects the absence of water
and the pump is set off but the pump sounds
like it’s straining badly: the valve is stuck.
2 There is a general short circuit: the coil may
be short-circuited due to micro leaks or elec-
trical shock.
3 The heater flooded: the impurities have pre-
vented the valve from closing properly.
2 Using a 14 mm wrench, remove the bolt “B”
that holds the coil in place and ease it out
of its housing. Under optimal conditions,
the removal is immediate but if parts are
blocked, force removal as much as possible.
