Door or Lid Latch Assembly If the washer lid won't lock the lid switch assembly might be defective. This is a very common problem. The lid switch assembly can fail either mechanically or electrically. Test any electrical switches with an Ohm meter for continuity. The switches should have continuity according to their design.

Main Control Board If the washer door won't unlock the problem might be the main control board. This is not common. Normally the problem is with the lock mechanism.

replace the lid lock ! its a safety measure. I would not recommend removing or bypassing lid lock. just replace it. without the lid lock it will work with lid open. good-day ! if you really what to bypass the lid lock. Find the wire that goes to the switch. Splice the wires together and the machine will think the lid is shut all the time. if you can not get top of washer off. just call an appliance center and give them the model and serial number. and they should be able to tell you. good-day !

Hi there the lid lock switch is faulty and needs to be replaced - cannot be bypassed unfortunately.
