KitchenAid Dishwasher Error Code Anti-Bacterial/Heavy + Quick Rinse

This button combination indicates a water inlet valve current sense error. The dishwasher's control board monitors the electrical current flowing to the water inlet valve and detected a reading outside the normal range. This fault stops the cycle and requires diagnosis of the inlet valve, its wiring, or the control board.

You should not attempt to operate the dishwasher while this error is present. A current sense error in the inlet valve circuit can indicate a short circuit or wiring fault that poses a risk of further electrical damage. Additionally, the dishwasher may not fill with water correctly, which could damage the pump or heating element if the appliance attempts to run dry.

A reset may temporarily clear the error display, but the fault will return if the underlying cause has not been corrected. To reset, disconnect power to the dishwasher for several minutes and then restore it. If the error reappears immediately or on the next fill cycle, the inlet valve, wiring, or control board requires physical inspection and diagnosis.

A knowledgeable DIYer can perform several diagnostic steps, including inspecting the wiring harness, checking connector seating, and testing the inlet valve solenoid coil with a multimeter. If the valve coil reads as open or shorted, replacing the inlet valve is a moderately involved repair that requires shutting off the water supply and disconnecting power. Control board replacement is more complex and may warrant professional service.

If the repair requires only reseating a connector or repairing a wire, costs may be minimal, typically under $50 for basic supplies. Replacing the water inlet valve itself generally costs between $40 and $120 for the part, plus labor if professionally serviced. A control board replacement is the most expensive scenario, with parts typically ranging from $100 to $300 or more depending on the model.
