F03 NTC wash sensor
open / short
circuit - Check efficiency of contacts on connector J005 (commutator) or
J12 (three-phase) on PCB;
- Check NTC ensuring that the impedance value at ambient
temperature (20°C) on wiring connector J005 (commutator) or J12
(three-phase) pins 1 and 2 is approximately 20 KOhm
- If measurement is incorrect check continuity of wiring J005
(commutator) or J12 (three phase), pins 1 and 2 / NTC;
- Check the same parameter directly on the NTC (20 KOhm);
- Renew NTC;
- Renew PCB.
F05
Pressure switch
empty condition
not reached or
drain pump
jammed - If status type pressure switch check correct operation of
component;
- Check efficiency of contacts of connector J006 (commutator) or J7
(three phase) on PCB;
- Check wiring of connectors J006 (Commutator) or J7 (three phase)
/ Pressure switch;
- Check continuity of pump on connectors J004 (commutator) or J11
(three-phase), pins 4 and 5 (in case of classic door lock); check that
impedance value is 170 Ohm +1- 10%;
- Check wiring of connectors J004 (commutator) or J11 (three-
phase), pins 4 and 5 / pump;
- Check pump and wall drain outlet;
- Renew drain pump;
- Empty tank, reprogram Main PCB then start autotest routine;
- Renew linear pressure switch;
- Renew PCB.
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.
