Signs an electronic control box has failed

Think of the control box as the brains of the appliance. It reads the buttons, dials and sensors, then switches power to motors, heaters, pumps or valves at the right moment. When the electronics fail, the symptoms vary. The appliance may be completely dead, the display may stay blank or flicker, buttons may stop responding, programs may stop partway through, or a fault code may keep coming back. Before replacing the box, rule out simpler causes such as a tripped safety switch, a loose plug or a faulty door switch.

Before fitting a new control box

Switch the appliance off at the wall and unplug it, or have a licensed electrician isolate it if it's hard-wired. Photograph every connector before unplugging anything so the looms go back in the same spots. Look for burnt pins or melted plugs on the old box, because a shorted motor, pump or heater can damage a new one too. Handle the electronics by the edges and keep them dry.
