Whirlpool Washer Error Code 4-3

Error code 4-3 means the control board detected that the wash motor is not running and cancelled the active cycle. The washer monitors the wash motor circuit during operation, and when it receives no response or detects abnormal resistance values, it triggers this code. The issue can originate from the motor itself, the wiring connections, or in less common cases, the control board.

No. When error code 4-3 appears, the washer has already cancelled the cycle to protect itself. Attempting to force additional cycles while this fault is active could worsen damage to the motor or wiring. Leave the washer unplugged until the cause has been diagnosed and corrected.

A reset may temporarily clear the code, but it will return as soon as the washer attempts to run the wash motor again and the underlying fault is still present. Unplugging the unit for a few minutes and restarting is a reasonable first step, but if the code reappears, the wash motor circuit needs to be physically inspected and tested before the machine can operate reliably.

Some causes of this error are DIY-friendly. Start by unplugging the washer and checking all wiring connectors in the wash motor circuit for looseness or corrosion, then reseat any suspect connections. If the motor itself has failed or wiring is damaged, replacing those components requires moderate mechanical skill and comfort working with appliance electrical systems. If you are not confident testing resistance values with a multimeter, a qualified technician is the safer option.

Repair costs vary depending on the root cause. Reseating a loose connector costs nothing beyond your time. A replacement wash motor typically runs in the range of $80 to $200 or more for the part alone, plus labor if you hire a technician. A control board replacement, if required, can add $150 to $350 or more. Getting a diagnosis first helps avoid replacing parts unnecessarily.
