Kenmore Dishwasher Error Code 4-4

Code 4-4 means the control board detected a failure in the wash motor circuit. The board attempted to run the wash motor and received no confirmation that it started. The fault could be a loose wiring connection, a blown motor fuse on the control board, a failed wash motor winding, or a bad motor drive circuit on the control board itself.

No. When the 4-4 code is active, the wash motor is not running, which means the dishwasher cannot circulate water through the spray arms. Running a cycle in this condition will not clean dishes and may cause the control board to log repeated faults. The dishwasher needs to be diagnosed and repaired before it can function normally.

Unplug the dishwasher before doing any testing. Locate the wash motor under the tub and disconnect its wiring harness. Set a multimeter to the resistance (ohms) setting and probe the motor terminals. A functioning motor will show a finite resistance reading, typically in the range specified on the wiring diagram for your model. An OL or infinite reading means the motor winding is open and the motor needs to be replaced. Also check that the wiring harness connector pins are clean and fully seated before concluding the motor is bad.

Start by unplugging the dishwasher or shutting off its circuit breaker. Then inspect all wiring connectors in the wash motor circuit and reseat any that appear loose or show signs of corrosion or heat damage. Use a multimeter to check the motor fuse on the control board for continuity and test the wash motor terminals for an open winding. If the motor fuse is blown or the motor shows no continuity, those components need to be replaced. If all those tests pass, the control board's motor drive circuit is likely the culprit.

Cost depends on which component is at fault. If only a wiring connection needs reseating, there is no parts cost and a DIY repair takes under an hour. A replacement wash motor typically costs $80 to $200 depending on the model, plus one to two hours of labor if you hire a technician. A replacement control board can run $100 to $300 or more. Checking connections and testing with a multimeter before ordering parts is the best way to avoid unnecessary expenses.
