If there are traces of burning on the
circuit board, refer to page 90
Detach the connectors and
measure on the component:
- across connectors 3 and 4
the circuit must NOT be
open (measure the resistive
value of PTC)
- across connectors 2 and 4
the circuit must NOT be
open (measure the resistive
value of PTC).
- across connectors 4 and 5
the circuit must be OPEN
(the numbers are printed on
the component).
Is the door safety interlock
is OK?
(fig. 28)
Instantaneous door interlock with
4 connections.
- fig 28 -
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 s
stem OK?
Replace the door
interlock and
restart the
diagnostic cycle
to check for
further alarms.
fig. 28
Replace the door interlock.
Is the machine working correctly?
Check for mechanical coupling
between the door interlock and the
door natch. Is the system OK?
Replace the door natch/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
Measure the continuity across
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.
