F06 Door lock fails to
close / open, door
lock PTC triac open
/ closed, mains
frequency signal
fault, mains power
signal fault - Check for water leaks that may affect connectors J004 or J11
(three-phase) causing the relative contacts to short;
- Check Door lock terminal board (any problems due to
aggression caused by manufacturing chemical residues that may
cause short circuits);
- Check
J004 / door lock wiring;
- Check door lock;
- Renew PCB.
F07 Wash heating
element relay open
/ diverter relay
sticking on drain
pump side - Check efficiency of contacts on connector J001 (commutator) or
J10 (three-phase) on PCB;
- Check continuity of wash heating element on connectors
J001 (Commutator) or J10 (Three-phase), pins 3 and 4.
The 1700W 230V heating element impedance value is 30 Ohm
+/
-
10%. If value is different renew wash heating element;
- Renew PCB.
F08 Wash heating
element relay earth
leak- age / wash
heating element
relay contacts
sticking - Check efficiency of contacts on connector J001 (commutator) or
J10 (three-phase) on PCB;
- Check leakage between the two ends and ground, impedance
should be at least 2 MOhm;
- Renew heating element;
- Renew PCB.
F09 Setting File error
detected by Main
PCB or Display
PCB - Disconnect appliance for 2 minutes. Check that correct
operation has been restored by starting the Autotest routine;
- Reprogram Main PCB;
- Renew main PCB;
- Renew display PCB.
F11 Pump not wired or
pump driving triac
short circuit - Check efficiency of contacts on connector J004 (commutator) or
J11 (three-phase) on PCB;
- Check continuity on connector J004 (commutator) or J11 (three-
phase), pins 4 and 5 (in the case of classic door lock);
- Check continuity of pump, ensuring that impedance value is 170
Ohm +/- 10%;
- Check wiring of connector
J004 (commutator) or J11 (three
phase) / pump;
- Renew pump;
- Renew PCB.
F12 Communication
error between Main
PCB and Display
PCB - Check efficiency of contacts on connector J010 (Commutator) or
J16 (Three-phase) on main PCB;
- Check efficiency of contacts on Display PCB;
- Check continuity of
J010 (Commutator) or J16 (Three-phase)/
Display PCB wiring;
- Disconnect appliance, wait for 2 minutes and reconnect to power
supply, then start autotest routine;
If problem persists proceed as follows:
- Renew main PCB;
- Renew display PCB.
