This washer is stopping in the latter part of the wash cycle and will not do anything at that point except you can hear a buzz from inside. The door is locked since water is in the tub. I pulled the drain hose off of the back and drained the water. The door latch released at that point. The machine was restarted at the beginning of the wash cycle and worked fine until the latter part of that wash cycle with the same end result. This washer is not at my house so I cannot observe all details but I am told that this is happening during a drain cycle.

Can anyone assist with the diagnostics.

Thank you.
