Maytag Dishwasher Error Code 4-3

Error code 4-3 means the dishwasher's control has detected that the wash motor is not running. The wash motor circulates water through the spray arms during a cycle, so this fault will prevent the dishwasher from cleaning dishes. The cause can be a loose connection in the motor circuit, a failed motor, or a faulty motor drive circuit on the control board.

The dishwasher will not complete a wash cycle with this fault active, so continued use is not productive. Beyond that, running the appliance with a potential wiring or motor fault is not recommended. Disconnect power and have the issue diagnosed before attempting further operation.

Resetting the dishwasher by disconnecting power may temporarily clear the code, but it will return as soon as the machine attempts to run the wash motor again if the underlying fault has not been corrected. The code will continue to appear until the loose connection, failed motor, or faulty control board is properly repaired.

Some repairs are within reach for a knowledgeable DIYer. After disconnecting power, you can inspect and reseat all connectors in the wash motor circuit, which resolves the fault if a loose or corroded connection is the cause. If resistance testing shows a failed motor or the control board needs replacement, those repairs require sourcing the correct parts and some comfort working with appliance electrical components.

Repair cost depends on the root cause. Fixing a loose connection costs little to nothing beyond your time. A replacement wash motor typically runs in the range of $75 to $200 or more for the part, plus labor if professionally installed. A control board replacement can range from $100 to $300 or higher for the part. Getting a diagnostic from a technician before ordering parts helps avoid unnecessary expenses.
