Second part of Hotpoint Ariston washing machine repair video
Model Aqualtis 8Kg AQ8F 292 U Super Silent Energy Class A ++ (The platform should be Arcadia)
Initially, the washing machine gave after a few minutes the error F01 with all the flashing lights, the basket and then the motor did not turn, looking on the net I found that the error F01 is due to an error of the board, more precisely dell'erroe triac of the engine.
Then I unmounted the board and I found a short IGBT (there are 6 and must be all working otherwise the engine does not run).
After replacing the IGBT the Ariston Hotpoint washing machine resumes operation, runs the cycle but when it comes to the centrifuge again from the error and the drain pump continues to discharge.
The problem in addition to the IGBT was also due to the engine connectors that I cleaned with shiny contacts
Material used for repair:
IGBT: goo.gl/u3eD9a
Conductive heat pad: goo.gl/enPP4m
Lucida contacts: goo.gl/DDz2im

0x24
Drain pump driving triac in diode mode
- Check efficiency of contacts of connector J004 (commutator) or J11 (three-phase) on PCB;
- Check continuity of pump on connectors J004 (commutator) or J11 (three-phase), pins 4 and 5 (in case of traditional door lock); check that impedance value is 170 Ohm +/- 10%;
- Check wiring of connector J004 / pump;
- RenewPCB.
0x31
Pressure switch full value off range (status pressure switch only)
- J006 or J7 (three-phase) causing the relative contacts to short;
- Check pressure switch board (possible problems due to manufacturing chemical residues that may cause short circuits);
- Check wiring of connector J006 (commutator) or J7 (three-phase) / pressure switch;
- RenewPCB.
0x32
Overflow value out of range (status pressure switch only)
- J006 (commutator) or J7 (three-phase) causing the relative contacts to short;
- Check pressure switch board (possible problems due to manufacturing chemical residues that may cause short circuits);
- Check wiring of connector J006 (commutator) or J7 (three-phase) / pressure switch;
- RenewPCB.
0x33
Pressure switch empty and overflow signal present simultane
- J006 or J7 (three-phase) causing the relative contacts to short;
- Check pressure switch board (possible problems due to manufacturing chemical residues that may cause short circuits);
- Check wiring of connector J006 (commutator) or J7 (three-phase) / pressure switch;
- RenewPCB.
0x41
Triac + dryer heating element relay open
- Disconnect appliance for 2 minutes. Check dryer heating element wiring and connectors;
- Check that correct operation has been restored by starting the Autotest routine;
- If fault reappears renew PCB.
0x42
Dryer heating element feedback fault
- Disconnect appliance for 2 minutes. Check dryer heating element wiring and connectors;
- Check that correct operation has been restored by starting the Autotest routine;
- If fault reappears renew PCB.
0x81
Hardware protection trip two to overcurrent (probably breakage of inverter branch)
- J1 causing the relative contacts to short;
- Check connector also on motor side;
- Disconnect appliance for 2 minutes. Check that correct operation
has been restored by starting the Autotest routine;
- If fault reappears renew PCB.
0x82
Incorrect reading of offsets from inverter channel U
- J1 causing the relative contacts to short;
- Check connector also on motor side;
- Disconnect appliance for 2 minutes. Check that correct operation
has been restored by starting the Autotest routine;
- If fault reappears renew PCB.
