E42: Problems with door aperture (3-contact device)

E42
Tests to be performed:
fig. 9
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 J1-3 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?
YES
Replace the door interlock.
Is the machine working correctly?
YES
Restart the diagnostic cycle to
check for further alarms.
