GE Dishwasher Error Code FL: Flood Detection and Repair
Updated: February 2026
The GE dishwasher error code FL (Flood) is a critical alert indicating that water has been detected in areas where it shouldn't be. This triggers immediate shutdown to prevent property damage.
Understanding FL Error
The FL error activates when the overflow protection system detects water in the base pan, excessive water in the tub, or leakage from hoses or seals. The dishwasher immediately stops all functions except the drain pump, which runs continuously to remove water.
Emergency Response Steps
- Step 1: The dishwasher should be actively draining when FL displays. Allow it to drain completely before investigating.
- Step 2: Turn off the water supply valve under the sink to prevent continued flooding if an inlet valve is stuck open.
- Step 3: Disconnect power once draining stops. You need to find and fix the leak source before restarting.
- Step 4: Tilt the dishwasher backward 45 degrees to drain water from the base pan. Have towels ready to catch spillage. This resets the base pan float switch.
- Step 5: Inspect all visible hoses and connections for leaks. Common problem areas include inlet hose, drain hose, and door gasket.
- Step 6: Check the door gasket for tears, gaps, or areas where it has pulled away from the tub. Replace if damaged.
- Step 7: Examine the water inlet valve for leaking. A stuck-open valve causes continuous filling and overflow.
- Step 8: Inspect the tub and internal hoses for cracks or loose clamps that could leak during operation.
After repairing all leak sources, let the dishwasher dry completely for 24-48 hours to ensure the base pan float switch drops. Restore water and power, then run a test cycle while monitoring closely for leaks. FL should not return if all leaks are properly repaired. Never ignore FL errors—they indicate active flooding that can cause serious damage.
