Kenmore Washer Error Code E43

E43 indicates a motor drive internal problem. The motor drive is the electronic board that controls power delivery to the wash motor. When the washer detects a fault within this drive, it stops operation and displays E43 to alert the user that service is needed.

No, you should not continue operating the washer while E43 is active. The fault indicates a problem within the motor drive system, and running the machine could cause additional damage to the drive, the motor, or connected wiring. Leave the washer unplugged until the fault is diagnosed and resolved.

A reset may temporarily clear the code, but if the underlying motor drive problem still exists, the error will return as soon as the machine attempts to run. Resetting is worth trying after correcting an identified cause, such as a low supply voltage, but it is not a fix on its own. Persistent E43 errors require proper diagnosis of the motor drive system.

The first step you can do yourself is to measure the AC outlet voltage and confirm it falls between 102V and 132V AC using a multimeter. You can also inspect the wiring and connectors around the motor drive for visible damage. If the voltage is correct and the wiring looks intact, the motor drive board itself has likely failed and will need to be replaced, which is a more involved repair.

Repair costs depend on the root cause. If the issue is simply an out-of-range power supply, there may be no parts cost at all. If the motor drive board has failed, parts and labor together typically range from $150 to $400 or more, depending on your location and the specific model. Getting a diagnosis before committing to repair is recommended.
