What the dishwasher is detecting
The control checks the wash motor circuit when it runs the motor. An open circuit, a blown motor fuse or a drive fault sets this code.
Causes listed for this condition
In the order the service documentation checks them. Documented causes come from the manufacturer's service documentation for these platforms; possible causes are based on how the system works; unconfirmed marks common assumptions that the documentation does not support.
- Documented A loose connection in the wash motor circuit or an open wash motor.
- Documented An open motor fuse on the main control.
- Documented A failed wash motor drive circuit on the control.
- Documented A failed wash motor.
Safe checks you can make
- Switch off the dishwasher's circuit breaker (or unplug it, if it plugs in under the sink) for one minute, restore power and run a short cycle to see whether the code returns.
- Note whether the code comes back right after a power reset or only after some cycles; that detail helps the technician.
Further diagnosis requires opening the appliance. Beyond the owner checks, diagnosis involves removing panels, testing components and checking wiring. We describe what a technician investigates, not how to do it yourself.
What a technician checks
- Checks the motor circuit and the control's motor fuse with power off.
- Separates a motor fault from a control drive fault before ordering parts.
Typical repairs and cost
Depending on what diagnosis finds, this code can lead to one of these repairs:
| Repair | Typical range | Labor |
|---|---|---|
| Dishwasher circulation pump and wash motor replacement | $300–$620 | Heavy |
| Dishwasher main control board replacement | $260–$590 | Moderate |
Typical total ranges for the Las Vegas area, parts and labor included. The final cost depends on diagnosis, the exact model, parts availability and whether other damage is found.
Can you keep using it?
Use with caution. The dishwasher cannot wash without the motor. Schedule service.

Repair or replace?
A fault code alone rarely justifies replacing a dishwasher. Most 4-4 repairs involve a single component once diagnosed. Replacement becomes worth considering when the unit is near the end of its typical 9–12-year life and the diagnosed repair is a major one. See the repair-or-replace guide.
