Washer displays E6; motor does not run or stops unexpectedly during wash or spin.

Safety first: Unplug the washer. Motor and inverter circuits can store energy; wait several minutes before touching components.

• Check for drum movement: Try to rotate the drum by hand. If it is seized or very stiff, there may be a mechanical obstruction or bearing failure rather than an electrical fault.
• Inspect wiring: Remove the rear panel and inspect the motor connector and harness for loose plugs, broken wires, or burn marks. Reseat connectors.
• Check motor brushes (if applicable): On Haier models with brushed motors, remove the motor and inspect carbon brushes. If they are worn below manufacturer minimum length, replace both brushes as a set.
• Examine the tachometer: Inspect the tach sensor on the motor shaft for damage or dislodgement. Ensure its connector is secure.
• If E6 persists: The inverter/drive board or main PCB may be defective. Replacement typically requires a professional technician due to high-voltage circuitry and calibration.
