Tests to be performed:
E43
E43: Problems with the component (triac) which actions the door
interlock
(3-contact device)
E43
Detach the connectors and
measure 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
OK?
To check the wiring, (with the door
open), measure the following
wiring connectors (fig. 4):
-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 circuit board and restart
the diagnostic cycle to check for
further alarms.
If there are traces of
burning on the circuit
board, refer to page 90
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.
