Last job of the day was this Beko dishwasher that will work now and again but when it doesn’t it flashes up P1. P1 is antiflood error from what I have found online but when I checked the base it was bone dry. I started it on a quick cycle and it ran perfectly, no leaks so I left it run for around 10 mins just to keep an eye on it and it was fine. I cancelled that cycle to get it to drain to try it again and this time it wouldn’t work. So now when you select a cycle it drains then pauses at the point you would expect it to fill for about 10-15 seconds then starts beeping and flashing P1. I was thinking maybe valve but it worked only 10 mins before and I think it comes up with P2 for a no fill fault. This customer seems adamant that she wants it repaired so any pointers would be great.
you are correct about the error code but the switch has 3 wires as its a changeover switch. could one of the wires from the board to the switch be broken ?
CO is the switch DPM drain pump connections KN4 , 5 are on the board
