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

E42
Checks to perform:
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.

Maximum time exceeded (255 seconds)
Check that all the connectors are inserted correctly
Is the door
correctly closed?
The door interlock is
traditional with
YES
3 connections as
represented in (fig. 9)?
NO
NO
NO
NO
YES
NO
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?
YES
Measure the continuity across
connector J1 (PCB) and the
door interlock connector.
Is the wiring OK?
YES
Replace the circuit board and
restart the diagnostic cycle to
check for further alarms.
Replace the door natch/the
door.
Replace the circuit board and
restart the diagnostic cycle to
check for further alarms.

48/121
Close the door correctly and
restart the diagnostic cycle to
check for further alarms.

Instantaneous door interlock
with 4 connections as
represented in (fig. 28)
Replace the door
interlock and
restart the
NO
diagnostic cycle
to check for
further alarms.
Replace the
wiring and restart
NO
the diagnostic
cycle to check for
further alarms.
