Samsung Dishwasher Error Code 3E — Wash Motor Error
What this means
The 3E error code indicates the dishwasher's wash pump motor is not responding to the control board's commands. The motor drives the spray arms to circulate water during the wash cycle. A jammed impeller, failed motor, or wiring issue can trigger this code.
Step-by-step fix
4 stepsReset the dishwasher
Turn off the circuit breaker for 5 minutes, then turn it back on. Start a new cycle to see if the error clears.
Check for obstructions in the sump area
Remove the lower dish rack and the spray arm. Remove the filter assembly and mesh screen. Look down into the sump area for any debris (glass, bones, plastic) that could be jamming the wash pump impeller.
Broken glass is a common culprit — handle with care.
Inspect the wash motor
Access the wash motor from under the dishwasher by removing the kick plate and bottom cover. Check that the motor wiring connector is firmly attached. Test the motor windings with a multimeter for continuity.
If the motor hums but the impeller doesn't spin, the impeller may be jammed or the motor windings may be partially burned.
Replace the wash motor if faulty
If the motor fails the electrical test or the impeller is permanently jammed, replace the wash motor assembly. Disconnect the wiring, unfasten the mounting hardware, and install the new motor.
Lay towels under the dishwasher — some water will drain out when you disconnect the motor.
When to call a professional
Wash motor replacement involves working under the dishwasher with water connections. If you are not comfortable with this type of repair, a technician can handle it efficiently.
