Hotpoint BFV620X - 30715930. Prewash led / light flashes continually. Might be in continuous drain mode? This all happened when the Bottom Spray arm came off during a wash cycle. Spray arm is now firmly back in place.
i did also check the inlet water filter which seems clean and fine.
I also spilled a kettle of water into the diswasher and it drained it out..
I just threw another kettle of water in now and it drained immediately - while on with light - pre wash flashing - so suggest in permanent drain mode.. so how do I stop that?
Still working on it here - If I turn it all off - then switch on - i get a long (few seconds) beep - where it then goes into the flashing prewash light - (drain mode?) and just seems to stay there??
Thank you Daniel. That was it. I had worked my way towards that possibility also, but great to have the confirmation from the expert. Knowing the problem was great but the real hard bit proved to be removing the dishwasher unit from a fitted kitchen and then putting it all back together. Something that you may do every day, - but I did manage it and it was a challenge. But thanks for help / information. 30 is fine for this good advice - now that the dishwasher is up and running again and "she that must be obeyed" is delighted with my work! Takeaway tonight , I think.
