KitchenAid Dishwasher Error Code Fill Failure LED

The Fill Failure LED means the dishwasher did not receive enough water during the fill phase of the cycle. The control detected that the tub was not filling as expected, so it stopped the cycle to prevent damage to the pump and heating element. Causes range from a closed water supply valve to a failed inlet valve, low water pressure, or internal pump issues.

No, you should not continue running the dishwasher while this error is active. Running the pump and heating element without adequate water can cause overheating and serious damage to those components. Resolve the underlying cause before starting another cycle.

Repair costs vary widely depending on the cause. If the fix is simply opening a supply valve or clearing a clogged inlet screen, there may be no parts cost at all. Replacing a water inlet valve typically runs between $25 and $75 for the part, plus labor if a technician is involved. More complex repairs involving the pump assembly or wiring harness can range from $100 to $300 or more depending on parts and local labor rates.

Start by checking that the water supply valve under the sink is fully open. Next, inspect the inlet hose for kinks and the inlet valve screen for debris or clogs. If the supply is confirmed good, test the inlet valve solenoid for electrical failure and check that the drain hose is routed with a proper high loop to prevent siphoning. If those checks pass, inspect the spray arm seating and pump impeller.

A reset may temporarily clear the indicator, but if the root cause has not been corrected, the LED will return as soon as the dishwasher attempts to fill again. Address the underlying issue, such as opening the supply valve or replacing a faulty inlet valve, before attempting to reset and restart the unit.
