Maximum time exceeded (PTC = 15 seconds)
E41
Detach the connectors and
effect measurement on the
component
(fig. 9):
- across connectors 3 and 5
the circuit must not be open
(the resistive value should
be measurable).
- across connectors 4 and 5,
the circuit must be open (the
numbers are printed on the
component).
Is the door safety interlock
is OK?
To check the wiring (with the door
open), measure the following
wiring connectors:
-between wires J1-3 and J1-1, the
circuit must NOT be open
(Measure the resistive value of the
PTC).
- between wires J1-1 and J1-2, the
circuit must be OPEN.
Is the system ok?
Replace the door
interlock and
restart the
diagnostic cycle
to check for
further alarms.
Replace the door locking device.
Does the appliance function
correctl
y
?
Is the door locking device securely
anchored to the latch?
Close the door correctly and
restart the diagnostic cycle to
check for further alarms.
YES
Replace the door latch or the
door.
Replace the circuit board and
restart the diagnostic cycle to
check for further alarms.
Restart the diagnostic cycle to
check for further alarms.
YES

NO
If there are traces of burning on the
circuit board, refer to page 90
The door interlock is
traditional with
3 connections as
represented in (fig 9)?
Measure the concinuity
between the connector J1
(PCB) and the door interlock
connector.
Is the wiring OK?
Replace the
wiring and restart
the diagnostic
cycle to check for
further alarms.
Replace the circuit board and
restart the diagnostic cycle to
check for further alarms.
