Dishwasher displays E10; unit may not start or may stop with no obvious water or drain issue.

Safety first: Turn off power at the breaker before accessing the control panel or main board.

• 1. Power reset: Switch off the breaker for 5 minutes, then restore power. Attempt to start a cycle to see if E10 clears.
• 2. Inspect control connections: Remove the inner door panel to access the control board. Check all harness connectors for secure fit and signs of burning or corrosion.
• 3. Check for moisture: Look for signs of water intrusion around the control area. Dry any moisture and correct door seal issues if present.
• 4. Verify line voltage: Ensure the dishwasher is receiving correct voltage (typically 120V AC in North America). Low or unstable voltage can cause control errors.
• 5. Replace control board: If connections are good and E10 persists, replace the main control board with an Insignia-compatible board, transferring any wiring one connector at a time to avoid miswiring.

Because control board replacement involves live-voltage circuits, consider professional service if you are not experienced with electrical work.
