Detach the connectors

and measure the value of

0Ω directly across the

terminals of the

automatically reset

thermostat. Is the value

correct?

YES

Measure if the automatically

reset thermostat is off (0Ω)

across terminals J5-2 ÷ J5-3 of

the wiring connector.

Is the value correct?

YES

NO

NO

Replace the

automatically reset

thermostat and restart

the diagnostic cycle to

check further alarms.

Replace the wiring and

restart the diagnostic

cycle to check further

alarms.

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.

NO

Detach the connnectors

and measure the value of

0Ω directly across the

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?

I valori sono corretti?

YES

Replace the wiring and

cycle to check for further

alarms.

Branch B

Across J5-1 and J8-4 measure a value

between:

51.5Ω ÷ 69Ω.
