E41: Door Open (4-Contact Device) - Electrolux EWM2100 Service Manual

E41
Instantaneous door interlock with
4 connections.
- fig 28 -
YES
To check the wiring (with the door
open), measure the following
wiring connectors (fig.4):
- between J1-1 and J1-3, the
circuit must NOT be open
(Measure the resistive value of the
PTC).
- between J1-1 and J1-4, the
circuit must be OPEN (Measure
the resistive value of the PTC).
- between J1-1 and J1-2, the
circuit must be OPEN.
Is the system OK?
YES
Check for mechanical coupling
between the door interlock and the
door natch. Is the system OK?
SI
Replace the door interlock.
Is the machine working correctly?
YES
Restart the diagnostic cycle to
check for further alarms.
