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
