What 4-4 means on a Kenmore dishwasher

Error code 4-4 on a Kenmore dishwasher indicates the control board has detected a failure in the wash motor circuit. Specifically, the control board monitors current draw and feedback signals from the wash motor during operation. When it detects no response or an abnormal signal, it throws the 4-4 code and halts the cycle. The fault can originate from a loose or corroded connection in the wash motor wiring harness, an open (burned-out) wash motor winding, a blown motor fuse on the control board itself, a failed wash motor drive circuit on the control board, or a completely failed wash motor.

For homeowners, the wash motor is the component responsible for pressurizing water and pushing it through the spray arms to clean dishes. When this motor cannot run, the dishwasher stops mid-cycle or refuses to start a wash cycle at all. The 4-4 code is the control board's way of flagging that it tried to run the wash motor and got no confirmation that it actually spun up.

Diagnosing this code requires checking connections in the wash motor circuit with a multimeter before replacing any parts. A loose connector or corroded terminal pin is the cheapest fix. If connections check out, the motor fuse on the control board and the motor windings themselves need to be tested for continuity.

Common causes of 4-4

  1. 01

    Loose or corroded wash motor wiring connection

    Wiring / connection

    A loose, burnt, or corroded connector in the wash motor circuit interrupts the electrical signal between the control board and the motor. This is the first thing to check before replacing any parts, as reseating or cleaning the connector can resolve the code without any part cost.

  2. 02

    Blown motor fuse on the control board

    Part replacement

    The control board contains a fuse specifically protecting the wash motor drive circuit. If the wash motor experienced an overload or short, this fuse can open and prevent the motor from receiving power, triggering the 4-4 code even if the motor itself is intact.

  3. 03

    Open or failed wash motor

    Part replacement

    An open motor winding means the motor's internal coil has burned out and can no longer carry current. Testing the motor terminals with a multimeter for continuity will confirm this; a reading of infinite resistance (OL) across the motor terminals indicates the motor needs replacement.

  4. 04

    Faulty wash motor drive circuit on the control board

    Part replacement

    If the motor, fuse, and all wiring connections test good, the drive circuit on the control board that sends power to the wash motor may have failed. This is the least common cause but requires replacing the control board to resolve.

Frequently asked questions about 4-4

What does error code 4-4 mean on a Kenmore dishwasher?
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.
How do I fix error code 4-4 on a Kenmore dishwasher?
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.
Can I still use my Kenmore dishwasher with a 4-4 error code?
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.
How much does it cost to fix error code 4-4 on a Kenmore dishwasher?
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.
How do I test the wash motor on a Kenmore dishwasher showing code 4-4?
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.
