KitchenAid Dishwasher Error Code F6E3

F6E3 means the dishwasher control has detected excessive suds or air in the wash pump. This prevents the pump from circulating water properly and will interrupt or stop the wash cycle. Common sources include the wrong detergent, improperly loaded dishes, a missing diverter disk in the sump, or a water leak inside the unit.

Resetting the dishwasher may temporarily clear the F6E3 code, but the error will return if the underlying cause is not addressed. A reset does not remove suds from the pump, replace a missing diverter disk, or fix a leak. Resolve the root cause first, then cancel the cycle or power cycle the unit to clear the fault.

If the fix is simply switching to the correct detergent or reloading dishes, there is no parts cost involved. Replacing a missing diverter disk is a low-cost repair, typically in the range of $10 to $30 for the part alone. If a pump seal, gasket, or other component is leaking and needs replacement, total repair costs including labor can range from $100 to $300 depending on the specific part and service rates in your area.

Start by letting the dishwasher run for about 1 minute, then open the door to check for excessive sudsing. If suds are present, drain the unit, remove dishes, and run a rinse-only cycle to clear the foam. Verify you are using a detergent specifically labeled for automatic dishwashers, and check that the diverter disk is present and seated properly in the sump at the bottom of the tub.

You should not continue running the dishwasher through a full cycle while F6E3 is active, as the pump may not be circulating water properly and dishes will not be cleaned effectively. If a leak is contributing to the fault, running the unit could allow water to reach electrical components in the base. Diagnose the cause before resuming normal use.
