Bauknecht mosógép program lefut, a végén F08- at ír.
Érdekes hibába botlottam. Csak nézek, mint hal a szatyorba. Minden program lefut szépen, melegít is, de a befejezéskor F08 hibát ír. fűtőbetétet és érzékelőt már cseréltem, de semmi változás. Ha valaki tud segíteni, megköszönném.
Bauknecht (Whirlpool) centri nem pörög fel rendesen
Sziasztok! Van egy Bauknecht WA Pure 16BW (Whirlpool) mosógép nálam. Minden megy rendesen rajta, de a centri nem pörög fel rendes fordulatra. Se mosóprogramnál, se sima centri programnál. 17 percet kiír centrizésre, 12-13nál jóideig pörget ballra-jobba, de a rendes furdulatot messze nem éri el, és 12-13 perc után (amin dolgozik vagy 5-6 percet) kiírja hogy END, pedig 1600-as fordulatok kellene mennie. Szerintetek mi okozhatja a hibát? Köszi előre is a segítő szándékot.
Bauknecht MCCD 1825 duo mikrosütő biztosítója kiolvad - Trafócserével MEGOLDVA
Sajnos kis terheléssel bekapcsolták és úgyhagyták. A panelen lévő T8A biztosító kiolvad ha indulna a magnetron.
Magnetron ment tönkre? Vagy lehet más is? Kapható ilyen alkatrész?
Ilyen jellegű hibát még nem javítottam, ezért minden tanácsot, segítséget előre is köszönök.
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)
