Measure if the automatically
reset thermostat is off (0Ω)
across terminals J5-2 ÷ J5-3 of
the wiring connector.
Is the value correct?
YES
Reset the manually reset
thermostat. To reset the
thermostat push the red button
(see fig. 23). Measure across
terminals J5-1 ÷ J8-3 and
across J5-1 ÷ J8-4 of the wiring
connector. In this way we will
check also the two branches of
the drying heating element. Is
the value correct as the one in
Tab. 2?
YES
Replace the WD board and
restart the diagnostic cycle to
check for further alarms.
Drying heating element
Branch A
Across J5-1 and J8-3 measure a value
between:
51.5Ω ÷ 69Ω.
Branch B
Across J5-1 and J8-4 measure a value
between:
51.5Ω ÷ 69Ω.
NOTE: The measurements must be
carried out with a room temperature of
25°C.

Detach the connectors
and measure the value of
0Ω directly across the
terminals of the
NO
automatically reset
thermostat. Is the value
correct?
YES
Replace the wiring and
restart the diagnostic
cycle to check further
alarms.
Detach the connnectors
and measure the value of
0Ω directly across the
NO
terminals of the manually
reset thermostat.
Is the value correct?
YES
Detach the connnectors
and measure the value of
the two branches of the
drying heating elements.
Does it correspond to the
value in Tab. 2?
Replace the wiring and
restart the diagnostic
cycle to check for further
alarms.
