Washer shows F10, may not start or may stop unexpectedly, often associated with communication between boards on some models.

Safety first: Disconnect power before removing the console or top panel. Electronic boards are static-sensitive; avoid touching circuitry directly.

Step-by-step:

• Power reset: Unplug for 5 minutes, then plug back in and attempt to enter a diagnostic mode (refer to tech sheet). If F10 returns, continue.
• Access console: Remove screws securing the control console, then carefully tilt it forward to access the user interface (UI) board and wiring.
• Inspect connectors: Check the ribbon cable and harness between the UI and main control (CCU). Unplug and reseat each connector firmly.
• Check for moisture: Look for signs of moisture intrusion or detergent residue on the boards or connectors. Dry gently if needed and correct any leaks from the dispenser.
• Visual inspection: Examine both UI and CCU for burnt components, cracked solder joints, or corrosion.
• Component replacement: If reseating connectors does not resolve the issue, replace the user interface board first (most common). If F10 persists, the main control board may also need replacement.
