Common Symptoms
- Washer does not drain or leaves water in the tub
- Drain-pump circuit or related component checks open
- Intermittent operation caused by loose, damaged, or vibration-affected harness connections
- Washer may stop or fail to complete a cycle when lower-component wiring continuity is lost
Check Before Replacing
- Disconnect electrical power before inspecting the harness or connectors.
- Visually inspect the lower harness and drain-pump connectors for loose connections, damaged insulation, pinched wires, or broken conductors.
- Check that the drain pump is free from obstruction before condemning the harness.
- Using the appliance-specific service documentation and an appropriate meter, check continuity between the drain-pump terminals and the main-control connections.
- If continuity is absent, inspect connector seating and harness routing before replacing the harness; do not assume the harness is defective without completing the applicable service checks.
Pro Tip
Pay particular attention to the drain-pump wires where the lower harness bends or is secured near the tub and cabinet; vibration or flexing can produce an intermittent open that may not be obvious during a quick visual inspection.

- Follow the service documentation for the exact washer model because access and harness routing vary by model.
- Document connector locations before disconnecting the old harness and ensure every connector is fully seated during reassembly.
- Route and secure the replacement harness as specified so wires are not pinched, stretched, or exposed to avoidable vibration.
- Restore power and verify washer operation only after all panels and connections are properly reassembled.
