Dishwasher will not start; control panel lights may be on but cycle will not run, sometimes beeps and displays F1E1 shortly after pressing Start.

Safety first: Unplug the dishwasher or switch off the circuit breaker before removing any panels. Water and electricity are present—use extreme caution.

Step-by-step checks:

• Power reset: Turn the breaker off for 5 minutes, then restore power and try a short cycle. Sometimes a transient control fault clears with a hard reset.
• Check for moisture on control: Remove the inner door panel (screws around the perimeter) and inspect the main control board housing for signs of moisture, corrosion, or burn marks. If moisture is present, dry the area thoroughly and identify any door gasket or vent leaks.
• Inspect wiring harness: Verify all harness connectors to the control board are fully seated and not burnt or loose. Gently tug each connector; reseat any that feel loose.
• Look for visible damage: If the control board shows burnt spots, swollen components, or a burnt smell, it is defective and must be replaced.
• Replace control board: If wiring and power supply are good and F1E1 persists, replace the electronic control board with the correct JennAir part number for your model. Transfer each connector one at a time to avoid miswiring.

When to call a technician: If you are not comfortable working with live voltage or cannot access the control safely, contact a qualified appliance technician.
