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

This button combination illuminating together signals a wash pump current sense error. The control board monitors the electrical current going to the wash pump motor and detected a reading outside the acceptable range. The dishwasher stops the cycle automatically to prevent damage to the motor or control board. The underlying cause can range from a jammed impeller to a failed motor or wiring fault.

No, you should not continue running the dishwasher until the error is diagnosed and resolved. A wash pump drawing excessive current can overheat the motor or damage the control board if the machine is repeatedly operated in a fault condition. Disconnect the dishwasher from power until the issue is identified.

A power reset may temporarily clear the error display, but if the underlying fault with the wash pump or its circuit is still present, the error will return as soon as the dishwasher attempts to run the pump again. Resetting without repairing is not a fix. The root cause must be identified and corrected for the machine to operate normally.

Some causes, such as debris jamming the pump impeller, can be cleared by a handy homeowner after disconnecting power and accessing the sump area. However, electrical testing of the motor windings and wiring harness requires a multimeter and some comfort with appliance disassembly. Control board replacement is generally straightforward but is a higher-cost repair that some homeowners prefer to leave to a technician.

Repair costs depend on the root cause. Clearing a debris obstruction costs nothing beyond your time. A replacement wash pump motor typically runs in the range of $80 to $200 for the part. A new control board can range from $150 to $350 or more for parts alone. Adding professional labor generally brings total repair costs to between $200 and $500 depending on the failed component.
