In case one or more buttons are not responsive, disconnect the appliance from the mains grid, disconnect the wire harness leading to the user interface control panel, and put the door back in place but with the wires disconnected. Do not close the door. Connect the dishwasher to the mains power supply and wait for no less than 7 seconds to allow the electronic control unit to power up. Now, shut the door. In case the main electronic control unit does not detect stuck buttons any longer with the wire harness disconnected, the dishwasher launches the drain pump. If it does, you will want to replace the user control panel. However, odds are high the drain pump won’t start. In this case, it is the main electronic control unit that needs replacing as it continues to detect stuck buttons even though the user control panel is disconnected.
