Maytag Dishwasher Error Code F4-E3

F4-E3 indicates that the wash motor is not running during a cycle. The control board monitors the motor circuit and trips this fault when it detects no motor activity or a problem in the drive and sense circuitry. The cause can be a loose connection in the motor circuit, a failed wash motor, or a control board failure. The dishwasher will not complete a wash cycle until the issue is resolved.

You should not attempt to run the dishwasher while this fault is active. Because the wash motor is not operating, the appliance cannot complete its cycle and will leave dishes uncleaned. Repeatedly attempting to start cycles without addressing the underlying fault will not cause immediate danger but does not resolve the problem and could mask worsening electrical issues.

A reset may temporarily clear the fault code from the display, but the error will return if the underlying problem has not been fixed. The F4-E3 code is triggered by an active condition in the wash motor circuit, so the control board will detect the same fault again the next time a wash cycle is attempted. Proper diagnosis and repair of the motor circuit or control board is required for a lasting fix.

Some causes of F4-E3 are DIY-friendly. After unplugging the dishwasher, you can inspect and reseat all wiring connections in the wash motor circuit, which sometimes resolves the fault if a loose connector is the culprit. If connections are secure and the motor needs replacement, that repair is more involved but manageable for experienced DIYers. A failed control board is typically the most complex repair and may warrant professional service.

Repair costs depend on the root cause. If the fix is simply reseating a loose connector, there may be no parts cost, only labor if a technician is involved. A replacement wash motor typically falls in the range of $100 to $250 for parts, with additional labor costs if professionally installed. A control board replacement can range from $150 to $350 or more for parts alone, making it the most expensive potential outcome.
