Dishwasher displays FA and may not start or may stop with unusual sensor readings.

Safety First: Turn off power at the breaker before attempting any internal inspection.

• Run a cleaning cycle: Use a dishwasher cleaner or a cup of white vinegar on the top rack and run a hot cycle to remove film and buildup that can affect the sensor.
• Check detergent use: Overuse of detergent can cause heavy film. Use only high-quality detergent and rinse aid recommended for Cove dishwashers.
• Power reset: After cleaning, reset power for 5 minutes and run a normal cycle to see if FA clears.
• When to call for service: If FA persists, the turbidity sensor or its wiring likely needs replacement by a technician.
