Maytag Dishwasher Error Code 8-3

Error code 8-3 means the drain motor drive circuit on the control board is stuck in an active state. The control board has detected that it cannot properly control the drain function. This points to either an internal failure in the control board's drain output circuit or a drain motor that has shorted or overheated and damaged the board.

It is not recommended to continue using the dishwasher with an 8-3 error active. A stuck drain circuit or a shorted motor can pose electrical risks including continued overheating of wiring and components. Disconnect power until the drain motor and control board have been inspected and any damaged parts replaced.

Repair costs vary depending on which components need to be replaced. A replacement control board typically runs in the range of $100 to $250 for the part alone, while a drain motor can add another $50 to $150. If professional labor is involved, total repair costs including parts and service can range from $200 to $450 or more depending on your location and the technician's rates.

Resolving 8-3 requires disconnecting power and inspecting the drain motor and wiring for signs of overheating or shorting before replacing any parts. If you are comfortable working with appliance wiring and component replacement, you can inspect the motor connections and replace the control board yourself. However, if you find burned wiring or a damaged motor, both components may need replacement, which adds complexity to the repair.

A power reset may temporarily clear the display, but the 8-3 code will return if the underlying fault in the drain drive circuit is still present. Because this is a hardware fault involving either the control board or the drain motor, a reset does not repair the defective component. Proper diagnosis and part replacement are required for a lasting fix.
