Disassembling the dishwasher door panels and testing the switches

1- Context of the defective dishwasher panel: the program selection in this dishwasher remains stuck at the 2:50 min cycle which starts upon turning it on. It is not possible to select  different dish washing program (cycle) whatever the button that is pressed.
2- Unplug the dishwasher and unscrew the internal stainless steel cover of the door.
3- The stainless steel cover and the outer white part of the door can now be separated.
4- Unplug the harnesses to free completely the white panel.
   
5- The white panel can now be moved completely out. 
6- Look first at the door switch. A malfunction of this switch could block the dishwasher panel. 
7- Unplug its connecting wires and check these were well connected. Remove the switch from its support. 
8- Test it 10 times with a multi-meter or by checking if it “clicks” when pushing the small button.
  
9- Inspect the cam that presses the button on the switch and check it is not broken. You can shift the switch to the opposite cam.
10- Spray a little of WD40 on the contacts prior to reconnecting the wires. Jump to step 14 if you do not have a multi-meter.
​
11- Now unscrew the board behind the control panel buttons.
12- Look at the opposite side to see the micro push buttons.
13- Test them one by one with a multi-meter. Operate each at least 10 times.

Buying a new dishwasher control panel (board)

You now need to buy a new set of electronic boards for your dishwasher.
​The set includes the boards on the control panel  along with the power supply whether needed or nut.
The dishwasher control board repair set costs typically around 60 US dollars or whatever equivalent currency in your country and has to be purchased from the appliances dealer unless you find it online.

Fitting the new dishwasher control panel and reassembling the door

1- Replace the control panel boards and make sure small gaskets like the one of this LED are well in place. 
2- You just replaced your control panel and are now ready to re-assemble the dishwasher door. 
3- Spray a little WD40 on the plugs prior to reconnecting them. Avoid any excess of oil and place a tissue behind. 
4- Reconnect the harnesses and make sure these “click” when engaged.
5- Keep the power supply in the original box as a spare in case it fails.
6- Test your dishwasher which should now change programs as per your selection.
