Frigidaire Dishwasher: not turning off
What is this symptom?
Is your Frigidaire dishwasher running continuously even after completing a cycle? This issue may be due to a defective electronic control board, a faulty user interface, or a stuck float switch. Understanding the root cause is essential for proper resolution.
Important Tips for Frigidaire Models
- Control board and user interface issues are reported as top causes for no shutoff.
- User forum reports of motor running continuously until door is open (older model anecdote).
Possible Causes
Defective electronic control board (main control board)
How to Identify: Dishwasher never enters idle state and display/control panel stays lit; resetting power does not fix; symptoms persist regardless of cycle stage.
Part: Electronic control board
Faulty user interface control (touch panel/buttons)
How to Identify: Buttons unresponsive, stuck, or cause constant signals to control board making unit think cycle is ongoing.
Part: User interface control
Drain pump failing or unable to drain water
How to Identify: Dishwasher runs continuously after cycle end and water remains in tub; audible pump noise that doesn’t stop.
Part: Drain pump
Stuck float switch / water level sensor
How to Identify: Float doesn’t move freely when manually lifted; dishwasher may think it’s always filled with water.
Part: Float switch (water level sensor)
Faulty temperature sensor / heating element causing incomplete cycle
How to Identify: Dishwasher runs continuously trying to reach target temperature; dishes not drying properly.
Part: NTC thermistor or heating element
