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

This button combination indicates a drain solenoid current sense error. The dishwasher's control board detected an abnormal electrical current reading from the drain solenoid circuit and halted the cycle. This error points to a problem with the solenoid itself, its wiring, or the drain valve it controls.

You should not continue running the dishwasher with this error present. A drain solenoid fault means the machine may be unable to properly drain water, which could result in standing water in the tub or incomplete cycles. Running it repeatedly without resolving the fault could also put additional stress on the control board.

A reset may temporarily clear the error display, but the fault will return if the underlying problem with the drain solenoid circuit has not been corrected. Resetting without repair is not a fix. The control board will detect the current sense error again as soon as the drain solenoid is activated during the next cycle.

Some steps, like inspecting wiring connectors and checking for visible harness damage, are accessible to a knowledgeable DIYer. However, accurately testing the drain solenoid coil resistance and diagnosing control board issues requires a multimeter and comfort working around live appliance components. If you are not confident with electrical testing, a qualified technician is recommended.

Repair costs depend on the root cause. A replacement drain solenoid or valve assembly typically ranges from around $20 to $80 for the part alone. If the control board needs replacement, parts costs can range from $100 to $300 or more. Adding professional labor generally brings total repair costs to between $100 and $400 depending on the diagnosis.
