Washer displays E10 and will not start or stops shortly after starting.

Safety first: Unplug the washer before removing control panels. Static discharge can damage electronics—ground yourself before touching boards.

• Check for power fluctuations: Ensure the washer is connected to a stable power outlet with correct voltage. Avoid using undersized extension cords.
• Inspect wiring harnesses: Remove the top and rear panels to access the main PCB and inverter board. Verify that all multi-pin connectors are fully seated and locked. Look for bent pins, corrosion, or burn marks.
• Reseat connectors: Disconnect and reconnect the communication harness between boards several times to clean contact surfaces.
• Visual board inspection: Examine both boards for cracked solder joints, burnt components, or moisture damage. If found, the affected board should be replaced.

Because communication faults can be intermittent and board-level diagnosis is complex, professional service is recommended if E10 persists.
