WA 7363, Nincs centrifuga (Bauknecht)
Sziasztok, fennti gépezet centrin kivül mindent csinál, első körben ennyit tudok rola. Köszönettel: Imre
Bauknecht WAT UNIQ632AAA DirectDrive felültöltős mosógép motor nem indul
Sziasztok! Bauknecht WAT UNIQ632AAA DirectDrive felültöltős mosógép motor nem indul. Nem volt még dolgom felültöltős DirectDrive motoros mosógéppel. Bekapcsolom centrifuga programra, ajtózár lezár, mikor a dobot kellene megpörgetnie, egyet-kettőt "nyekken" majd csend, kb 1 perc múlva ugyan ez és utána kiírja az F07 hibakódot. Ahogy néztem neten ez a motor Triak hibára-ra utal, de mivel ez DD motor nem triak hanem egy külön meghajtó IC vezérli. Azt kellene kiderítenem hogy mi a hibás. A DD motor, a hal szenzor, vagy a meghajtó elektronika. Amiket vizsgáltam: - A motornak 3 kivezetése van, mindegyik között 15 Ohm-ot mérek. - a vezérlő elektronikán van egy 400V-os kondenzátor azon csak akkor van feszültség egy pillanatra mikor a motor próbálna elindulni (nem tudom ez jó-e így).

Bauknecht WAK74 washing machine error F8 persisting after change of heating element.
Hello,

I have a washing machine (Bauknecht WAK74 (8583 642 03011) ) that had an F8 error due to a bad heating element. After changing it, the washing cycle (also the test program when hitting the "löschen" (delete) button a couple of times does more or less ) runs through, it is heating fine, but the F8 error is still being displayed.

I checked, cleaned, enhanced all the contacts, also of various other places I could reach to make sure it won't detect it e.g. due to vibration shortly causing a higher impedance. 


I am a bit out of my comfort zone here (usually doing industrial stuff) so not having any experience with the brand and only service manuals from similar machines I am not quite sure if
  • there is something else that could cause the F8 error that happened during the repair.
  • there is a procedure needed to reset the error from the machine
  • the error is really triggered each time the program (or test) runs, or if it is saved in the eeprom
Unfortunately I don't have a "clean" eeprom to just overwrite the old one. One test I did though was disconnect the NTC, leading to another error, then reconnecting it. The test program would still display the NTC error, but after writing back the old eeprom it didn't. So my suspicion is that the current eeprom might somehow contain the F8 error and overwriting it with a clean one might be all thats needed...

( I also grabbed the µC code and tried to disassemble/decompile it in ghidra but didn't have the time to get very far with it)
