The F8 error code on a Kenmore dishwasher points to a water level sensor (float switch) malfunction. The dishwasher uses a float switch to monitor the water level inside the tub. When this sensor malfunctions, the dishwasher either overfills (creating a leak risk) or underfills (reducing cleaning performance), triggering the F8 error to protect the appliance and your home.
Causes of the Kenmore Dishwasher F8 Error
- Float switch stuck in the up (closed) or down (open) position
- Debris or food particles jamming the float assembly
- Wiring fault between the float switch and control board
- Defective float switch component
- Water inlet valve staying open (causing overfill)
Troubleshooting Steps
- Locate the float assembly at the bottom of the dishwasher tub (typically a dome-shaped or cylindrical plastic cap). Remove any debris and ensure it moves freely up and down.
- Clean around the float assembly thoroughly.
- Reset the dishwasher and run a test cycle.
- If the error returns, the float switch or inlet valve requires professional inspection.
An unresolved F8 error can result in overfilling and serious water damage. Contact our certified technicians to diagnose and repair this issue before it escalates.
