How to Replace Dishwasher Electronic Board ?
Remove The Top Control Panel
Let’s get properly started now the. the first thing to do is to loosen the lower door skin, which you do by removing the screws on the back (There is no need to remove them completely, just loosen them as much as you can)
With you loosening these screws that hold the lower door skin in place, it will give you enough room to be able to then proceed to remove the top control panel. Again this is done by undoing the screws that are currently holding it in place.
Top Tip: We have left this final screw till last for a specific reason – it is keeping the two panels together. Once this screw is removed, you will be able to lift up the door and gently ease the control panel away (When removed you can just let it rest against the door – but making sure not to scratch the fascia)
Remove The Sensor
Now that the control panel is out of the way, you can see things more clearly. If we follow this black lead, you can see that it attaches to a sensor, and you will need to lift that out before you are able to remove the control board.
Remove The Control Board From Control Panel
This really is easy to do, you just need to undo these two screws completely, and then proceed to loosen this one.
Please Note: It’s worth mentioning that before you loosen the last screw, behind the control board there will be a light guide that will fall down when the control board has been released – just remember to replace this when replacing your new control board.
Disconnect The Electrical Connections
Now that you have freed the control board from the control panel, you need to disconnect the electrical connections from the old board and replace them with the new one (A lot of these connections are held in place by plastic tabs, which you have to pull away before being able to remove the connection)
Fit Everything Back Into Place
Once all the electrical connectors are connected you can replace your light guide into position, and then you can re-screw the control board into place. You next need to replace the sensor back in the door (be careful of sharp edges)
The final thing left for you to do is to refit the control panel to the door and screw it all together again. Once the control panel is screwed into place, you can tighten the screw on the lower door skin.
