Is the resistance of the pump
about 150-200 Ω? (measure
across connectors J7-1 and
J7-9 on circuit board side -

Is the resistance of the pump
about 150-200 Ω?
(measure directly on the
pump) -see fig.5-
Check and if necessary replace the wiring and restart the
diagnostic cycle to check for further alarm conditions.
Measure across connectors J7-1 / J7-9 and the
structure of the appliance - fig.6 -
Is there current leakage?
Replace the main circuit board and restart the
diagnostic cycle to check for further alarm
conditions.
Replace the pump and restart
the diagnostic cycle to check
for further alarm conditions.
