Is anything coming up on the display on the left hand side of the panel?
Also have you tried holding the programme button in and then turn the dishwasher on and keep both on/off button and programme button held in for about 10 seconds to see this does anything?
The display on the left hand side shows:
Yes, I have tried the programme and power buttons simultaneously.Nothing happens.
Ok that's fine. Have you tried removing the plug from the socket and leaving it for 20 mins as this can sometimes reset the electronics.
If its still the same then remove the wooden door and from there remove the plastic control panel. There you will see 2 control boards. One on the left with the screen and the other is the programing board. Check the wiring connections to there is fine.
Disconnect the wire and refit it a few times and then see if this gets it going.
If its still the same then im afraid its a faulty control board and will need to be replaced. Now when you get the new board it will come with the main board on the left and the programing board and the wiring. It comes complete so just a case of swapping over.
If you want the part number for the control board its###-##-####/p>
But just check the wiring in case it poor connections but if that's fine then its looking like a faulty control board.
