Washer shows E10 and will not start or stops mid-cycle, often related to communication between boards

Safety first: Unplug the washer before removing the top or rear panels. Electronic boards are sensitive to static and moisture.

• 1. Power reset: Unplug the washer for at least 10 minutes to discharge capacitors, then plug back in and try a cycle. Sometimes transient errors clear.
• 2. Access control boards: Remove the top cover. Locate the main control board (usually behind the control panel) and the motor inverter board (often near the motor or side panel).
• 3. Check wiring harness: Identify the multi-wire communication cable between the boards. Ensure both ends are fully seated. Look for bent pins, corrosion, or damaged insulation.
• 4. Inspect boards visually: Look for burnt components, bulging capacitors, or scorch marks on either PCB. If present, the affected board should be replaced.
• 5. Professional service: If E10 persists after reseating connectors and there is no visible damage, board-level diagnosis is required. Replacement of the inverter or main PCB should be done with the correct Casarte part number.
