Frigidaire dishwashers have a series of lights that illuminate when a cycle is selected, when it is currently in progress and when the dishes are clean. However, if the lights are flashing, it means something different entirely, and it is important to determine what the flashing light indicates to the user.
When the lights on a Frigidaire dishwasher are blinking, the first thing to do is perform a basic reset. To do this, simply unplug the dishwasher or flip off the circuit breaker and wait a few minutes before restoring power. Then restart the dishwasher and make a new wash selection.
The door on the dishwasher must be fully closed and latched before the dishwasher will start washing. If the door is not closed or the door switch is not making full contact with the door, the "Start/Resume" light will flash. Open and shut the door then press "Start" to resume the wash cycle.
While the "Clean" keypad normally illuminates when the dishes are clean, a blinking "Clean" keypad indicates a water temperature problem. Run the hot water at the kitchen sink then use a thermometer to verify that the hot water temperature in the home is at least 120 degrees Fahrenheit. Try turning up the heat on the home water heater. If this doesn't resolve the problem, contact a plumber.
Hi Temp Wash or Rinse Keypad
Frigidaire dishwashers with a "Hi Temp Wash" and a "Hi Temp Rinse" must warm up the water that will be used in the cycle and automatically pause while the water is heated. During this time, the "Hi Temp Wash" or "Hi Temp Rinse" button will flash to indicate that the cycle has paused. The wash cycle will resume when the water temperature is reached, and the light on the keypad should stop flashing.
