EC1: Water fill solenoids blocked
EC1
The flowmeter detects water filling even if the solenoid is not controlled
EC1
Tests to be performed:
Open the drawer
and check which
solenoid leaks and
replace it.
Restart the
diagnostic cycle to
check for further
alarms.
As soon as the
appliance is switched
on does the solenoid
start to fill water?
Open the drawer and check which
solenoid leaks and measure between
the wiring connector of the relative
solenoid and the appliance housing if
there is any current leakage (fig.6
and tab. 1).
Is there any leakage?
Replace the main circuit
board and restart the
diagnostic cycle to check for
further alarms.
Does the
appliance fill in
water when the
main switch is off?
Replace the main circuit
board and restart the
diagnostic cycle to check for
further alarms.
Replace the wiring and restart the
diagnostic cycle to check for further
alarms.
