My whirlpool washer model LHW0050PQ won't agitate or spin....front loader model. It locks the door, fills up water then just sits there. Click noises come from it but the nothing happens. After a while the washer will pump and drain the water. When it is done the "DONE" lights up but flashing and the door won't open. I have switch the dial to "stop" and wait for the door to unlock to allow me to open the door.
