Washer motor appears to be running. washer will not agitate or spin. Motor coupling is not broke, there is a little bit of rubber dust on floor, but nothing major. motor spindle turns easily, as does the spindle end where the coupler connects to. the tub agitater just does not move. I checked the lid switch on the cabinet top after removal for continuety, this is ok. I tried to check at the white plug but nothing. Does the washer need to be on to check the plug? When I cycled the selctor switch to different wash cycles, all it would do is fill with water, hum like crazy, drain, but not move. What am I missing to do?
Any help would be great.
