Dishwasher shows E13; unit may stop with water in the tub and not proceed to the next stage.

Safety first: Turn off power at the breaker before accessing internal components.

• 1. Perform a hard reset: Switch off the breaker for at least 5 minutes, then restore power and attempt to run a different cycle (e.g., Quick instead of Normal).
• 2. Check harness connections: Remove the lower access panel and inner door panel. Inspect all harness plugs to sensors (pressure switch, NTC, flow meter) and the control board. Reseat each connector.
• 3. Inspect for damage: Look for pinched wires, rodent damage, or corrosion at connectors and repair as needed.
• 4. Run diagnostic mode: If your Insignia model supports it, enter diagnostic mode per the service manual to identify which sensor is causing the conflict.
• 5. Replace control board if needed: If all sensors test good and wiring is intact, the main control board may be defective and require replacement.

Because E13 can involve multiple subsystems, professional diagnosis is recommended if basic checks do not resolve the issue.
