Bauknecht BIRA4DP8FS3PT be építhető sütő F03 hibakód.
Tisztelt kollégák. Segítséget szeretnék kérni a BIR4DP8FS3PT , 855653601100 sütő javításában.Be kapcsoláskor az óra és a  sütési program beállítása  és indítása után semmi nem történik, kb fél perc után adja a f03 hibakódot.Hibakód megjelenése után nem reagál semmire. Áramtalanítás után újból lehet állítani mindent. A tulajdonos azt mondta mikor megvették ezzel a hibával javították és akkor termisztort cseréltek benne.A termisztort kivettem 1Kohm az ellenállása kb 20fokon, ha melegítem fokozatosan növekszik.Sajnos ennek az értékét sehol nem találtam meg, és szerviz programos sem.
Köszönöm a segítségeket.
Tisztelettel.

OBOD Bauknecht fagyasztó ajtógumi
Üdv A fenti készülék pontos típusa VZ20 talán. 200L-es álló fagyasztó aminek az ajtógumiját illene cserélni. Körülnéztem de nem igazán találtam csak mintha a SINI árulna 17000ft-ért. Nem túlzás ez? Tudtok jó áron ajtógumit. Köszi Laci
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) 
Bauknecht TK Care 6 B Di szárítogép F6 hiba
Űdv. Mindenkinek . Leegyszerűsítve Wpool 6.érzék panelról van szó (ennek van külön panelon a nedvesség érzékelője ) és a fűtőröl jövő NTC ellenállással a panelon van sorba egy R66 poz. számmal smd ellenállás ami megszakadt és az értéke kellene mert nem olvasható . Tettem bele próbára 10K , de az érzésem , hogy túl melegíti a ruhákat . Esetleg jó jönne valami infó , hogy mekkora hőfok kell , hogy legyen a dobba azt megpróbálom kikísérletezni az értéket.
