Went to a Miele G1220Sc dishwasher, it starts ok, drains, fills and then when the circulation pump goes to start it immediately stops, then it tries again and again with just a short pulse of the circ pump, you can here the relay on the pcb click on and off. I have had the circ pump out and all looks fine, nothing stuck in the impellor or any tightness. So the question is, do I blame the pcb or the pump or am I missing something. Taking a guess could be very expensive. Any help would be great.
Thanks Barry.Re: Miele dishwasher
Don’t these have to energise the pressure switch (think it’s on or above the circ pump) to keep the circ pump switched on, if it don’t sense enough pressure it cuts the pump out.
Usually something simple blocking the pump, piece glass,bone,pip etc if not I would be looking down the lines of pressure switch etc first before i looked at the pcb.Phil
Re: Miele dishwasher
No there isn’t anything in there and it doesn’t energize the pump long enough to build to that pressure, I have also tested the capacitor.
Re: Miele dishwasher
This may help ive had this problem before and i had to clean out the pressure switch it was really blocked up inside the other reason this has happened could be the reed switch not measuring in enough water just as a test pour in about an extra 1litre or so of water and see if this fixes it, hope this helps.
