KitchenAid Dishwasher Error Code F6E1

F6E1 indicates that the dishwasher detected a low or absent water supply due to a mechanical problem. The control monitors water entering the tub and triggers this fault when the expected fill level is not reached within the allotted time. Possible causes include a closed supply valve, a detached drain loop causing siphoning, a clogged fill valve, a stuck overfill float switch, or an internal water leak.

Resetting the dishwasher by canceling the cycle or cutting power may temporarily clear the code, but it will return if the underlying mechanical problem is not corrected. The F6E1 fault is triggered by an active condition detected during the fill cycle, so the fault will reappear as soon as the dishwasher attempts to fill again without adequate water present.

Repair costs vary depending on the cause. If the issue is simply a closed valve or a misrouted drain hose, there may be no parts cost at all. Replacing a fill valve typically ranges from around $50 to $150 in parts, with additional labor costs if a technician is involved. More complex repairs involving internal leaks or multiple failed components can push total costs higher, generally in the $150 to $350 range depending on your location and service provider.

Start by confirming the water supply shutoff valve under the sink is fully open and that the supply line is not kinked. Next, check that the drain hose high loop is properly secured to prevent water from siphoning out. If supply and drainage are both correct, inspect the fill valve inlet screen for debris and check the overfill float switch for freedom of movement. If none of these steps resolve the issue, a failed fill valve or internal leak may require professional repair.

You should not attempt to run a full wash cycle while F6E1 is active, as the dishwasher is not receiving enough water to operate properly. Running the unit in this condition can stress the wash pump and heating element. If the cause is an internal leak, continuing to operate the appliance could result in water damage to surrounding cabinetry or flooring.
