Tests to be performed:
To check the wiring (with the door
open), measure the following
wiring connectors (fig. 4):
- between wires J1-3 and J1-1, the
circuit must NOT be open
(measure the resistive value of the
PTC).
- between wires J1-3 and J1-2, the
circuit must be OPEN.
YES
Is the door locking device securely
anchored to the latch?
YES
Replace the door locking device.
Does the appliance function
correctly?
YES
Restart the diagnostic cycle to
check for further alarm conditions.
