Hi Dave

Made some progress today, unfortunately its no longer possible to buy a new control board so……

I replaced one of the relays on the control board as it had failed. The dishwasher now steps through all of the cycles without issue, whereas before it was just stuck continually on the wash cycle and did not move on. The machine now drains when I first power on for 15 sec approx. and drains before the rinse cycle but then sticks on drying stage and does not finish just keeps on going and going. There are another 2 smaller relays on the board that I will also replace tomorrow just in case they have failed preventing the machine from completing a full cycle.

Yes, it’s an old machine too – thanks again

Hi Dave, thanks for all the pointers they are really appreciated. I have now continuity checked the 2 cables from the drain motor back to the control board connector block everything is fine with the cables. I removed the PCB and noticed damage to the circuit board, looks like one of the components has failed. Would you know where best to try and get a replacement board? Thanks again for all your help it is really appreciated.

Regards

Will

Thanks Dave I will double check the cabling to the pump. The pump does work if I over fill the machine. Also noticed that when the machine is set to a quick wash this should last for 30 mins. As soon as I select quick wash the display shows 0 and the cycle will not stop.Starting to think the control board is faulty? as normally if the display is showing 0 the cycle has finished.

Thanks Dave, checked the wiring under the door and all visually looks ok – although it’s old it’s hardly been used. Thanks for your help

Hi Dave, thanks for the reply – FD7905 there is this number near the FD number 370019 the ENR is SE26230GB /12

Thought the issue originally was the drain pump as the machine was not draining water. But then noticed that the cycles just never seem to finish and machine is full of water when I open the door.

I checked the original drain pump with a meter and this looks to be fine. Pump only kicks in when I activate the Microswitch next to the float switch?
