KitchenAid Dishwasher Error Code F10E4

F10E4 means the dishwasher's control board cannot confirm that the diverter, an internal valve that routes water to different spray zones, has reached its required positions. The fault points to a corroded or loose connection in the diverter circuit, or an open or shorted diverter sensor or motor. The dishwasher will interrupt its cycle until the underlying problem is corrected.

Running the dishwasher while F10E4 is active is not recommended. The diverter fault means water may not be distributed correctly to the spray arms, resulting in poor cleaning. More importantly, if the fault is related to sump leakage, continued operation could cause water damage inside the appliance cabinet or to surrounding cabinetry.

Repair costs vary depending on the failed component. Cleaning or reseating corroded connections has no parts cost and only requires your time. A replacement diverter sensor or motor will typically add parts costs on top of any labor if a technician is involved. If the entire sump assembly requires replacement, parts and labor costs combined can range from roughly 150 to 400 dollars or more, depending on parts pricing and local labor rates.

A knowledgeable DIYer comfortable using a multimeter can attempt this repair. The first step is to unplug the dishwasher, then inspect and test the wiring connections, diverter sensor, and diverter motor in the sump area. If the wiring checks out and the motor or sensor tests as faulty, those components or the entire sump assembly will need replacement, which is a more involved repair that some owners prefer to leave to a technician.

A reset may temporarily clear the fault code, but F10E4 will return as soon as the dishwasher attempts to operate the diverter and the same underlying problem is present. A reset does not repair corroded connections, a failed sensor, or a faulty motor. The root cause must be diagnosed and corrected for the code to stay clear.
