Re: Bosch Washing Machine Programme fault wfo2867gb15
Seem to remember something similar on another WFO series. IIRC it was, tripping when heater kicked in. When I got to it, confirmed the heater was the culprit. Fitted new heater and it kept jumping time at the heating stage similar to your description and also not heating. Customer admitted she kept on trying machine despite it tripping everytime. So presume she damamged the pcb but she didn’t want to take it any further do couldn’t confirm it. May/may not help you – could be heater and pcb repair/replacment. HTH
