Front loader he washer will not spin on any cycle, starts to drain then stops with small amount of water left. Checked drain and pump, replaced door inerlock and motor controller, no change. What’s left ??
Well one of those should have fixed things.
First thing to do is clean out the pump and drain lines. If that doesn’t fix things, use the tech notes inside the lower service panel to do some testing. Check the wiring between the door lock assembly and the control unit. Finally, you may have to change out the control unit on spec.
