Dishwasher displays FE and may not start or may shut down unexpectedly.

Safety First: Turn off power at the breaker before opening the electrical junction box or accessing wiring.

• Check breaker: Ensure the dishwasher's dedicated breaker is fully in the ON position and not tripping repeatedly.
• Verify dedicated circuit: Cove dishwashers should be on a dedicated circuit. Avoid sharing with disposals or other heavy loads.
• Inspect junction box (qualified persons only): Under the dishwasher, verify that wire nuts are tight and there are no signs of burning or melted insulation.
• When to call for service: If FE persists with proper voltage, the internal power supply on the control board may be failing and should be replaced by a technician.
