What Does Error F6 Mean?
The Whirlpool Dishwasher error F6 indicates a water fill fault, meaning the appliance is not detecting incoming water despite attempts to fill. This issue often manifests with the display of F6 or six flashes, failure to fill with water at startup or during the cycle, and insufficient water entering the tub. Common causes include an interruption in the water supply, obstructions in the water inlet components, or issues with the float switch or water level sensor.
Common Symptoms:
- Dishwasher displays F6 or six flashes
- Dishwasher fails to fill with water at start or early cycle
- No water or insufficient water entering tub during fill phase
Possible Causes
- Water supply interruption (no water entering) (medium)
- Obstruction or failure of water inlet components (inlet hose, valve, filters) (medium)
- Float/level detection or sensor issue preventing water detection (low)
How to Fix Error F6
DIY Fix Check basic water supply and reset
- Ensure the water supply tap feeding the dishwasher is fully open.
- Inspect the inlet hose for kinks, bends, or visible damage that could block flow.
- Turn off power to the dishwasher and wait a few minutes to reset error then restart to see if F6 clears.
Technician Only Inspect and test inlet and detection components
- Turn off power and water to the dishwasher.
- Disconnect and examine the inlet hose and water inlet valve for blockages, internal debris, or failure.
- Test water inlet valve electrically and replace if it does not open/respond.
- Check float switch and any water level sensor for proper movement and signal continuity.
- Verify water pressure at inlet meets specification and hoses are not damaged.
Parts needed: water inlet valve, inlet hose, float switch or water level sensor
- If water supply and inlet components check normal but F6 persists, indicating potential internal sensor or control communication fault.
- If there are signs of leaks, electrical faults, or part failures you cannot safely diagnose.
