Washer displays F11 and may stop mid-cycle, often during spin or drain; communication error between boards.

Safety First: Disconnect power before accessing internal components.

Step-by-step checks:

• 1. Locate control boards: On many Inglis front-load models, the main control (CCU) is under the top panel and the motor control (if present) is near the base.
• 2. Reseat communication harness: Identify the harness labeled for serial communication (often multi-wire). Unplug and firmly reconnect at both boards. Look for bent pins or corrosion.
• 3. Inspect for moisture: Check for signs of water leaks near the control boards. Dry any moisture and correct the leak source (door boot, dispenser, or hoses).
• 4. Check ground connections: Ensure the cabinet and control board grounds are tight and free of rust. Poor grounding can cause communication errors.
• 5. If F11 persists: One of the boards is likely defective. Replace the main control board first (most common), then the motor control board if the issue remains.

Warning: Do not attempt to repair circuit boards at component level unless you are qualified; replace with OEM parts.
