It sometimes pumps but mostly either lights all its display up or settles on the two top lights flashing with the small start one rapid flashing. I think this signifies a ‘comms’ error, checked all connections between fascia and main board, tweaking the wee ones with a pin but no joy. New main board the likely solution ?? 😕 Thanks, Eddie 🙂 February 12, 2013 at 7:56 pm #390030 hillyParticipant Re: HPT BWD 129 washer dryer random lights flashing.

Fitted exchange main board from EMW which seems to have cured it. Eddie. 🙂 Author Posts Viewing 3 posts - 1 through 3 (of 3 total) You must be logged in to reply to this topic.
