Kenmore Dishwasher Error Code 10-2

Vent wax motor electrical problem

Kenmore codesKenmore dishwasher codes

Vent wax motor electrical problem — loose connection in vent circuit, open vent wax motor, open fuse on control to vent, or faulty vent drive circuit on control (not all models).

First step from the service manual

Unplug dishwasher or disconnect power and check resistances of vent wax motor and all connections in the vent circuit. Refer to fuse service & diagnostic checks.

What 10-2 means on a Kenmore dishwasher

Error code 10-2 on a Kenmore dishwasher signals that the control board has detected an electrical problem in the vent wax motor circuit. Specifically, the control is seeing a fault that could stem from a loose or broken connection in the vent wiring, an open (failed) vent wax motor, a blown fuse on the control board feeding the vent circuit, or a failed vent drive circuit on the control board itself. Note that not all Kenmore dishwasher models include a vent wax motor, so this code only applies to models equipped with this component.

The vent wax motor controls a small flap or door that opens to release steam and moisture from the tub during and after a wash cycle. When the control board sends power to this motor and receives an unexpected electrical response, or none at all, it logs the 10-2 fault. The dishwasher may stop mid-cycle or refuse to start a new one.

The first step before any further diagnosis is to unplug the dishwasher or shut off its circuit breaker, then check the resistance of the vent wax motor with a multimeter and inspect every connector in the vent circuit for corrosion or looseness. A blown fuse on the control board should also be checked as part of the service diagnostic procedure.

Common causes of 10-2

  1. 01

    Loose or corroded connection in the vent circuit wiring

    Wiring / connection

    A disconnected, corroded, or damaged connector in the wiring harness between the control board and the vent wax motor breaks the circuit and triggers the 10-2 code. This is the most common cause and should be inspected first before any parts are replaced.

  2. 02

    Open (failed) vent wax motor

    Part replacement

    The vent wax motor itself can fail internally, resulting in an open circuit that the control board detects as a fault. A multimeter reading of infinite resistance (OL) across the motor terminals confirms the motor has failed and needs replacement.

  3. 03

    Blown fuse on the control board vent circuit

    Part replacement

    A small fuse on the control board protects the vent drive circuit. If this fuse has opened due to a power surge or a short in the vent wiring, the control board can no longer power the vent wax motor, producing the 10-2 fault.

  4. 04

    Faulty vent drive circuit on the control board

    Part replacement

    If the wiring, connections, fuse, and wax motor all test within spec, the vent drive circuit on the control board itself may have failed. This is the least likely cause but requires control board replacement if confirmed.

Frequently asked questions about 10-2

What does error code 10-2 mean on a Kenmore dishwasher?
Error code 10-2 means the control board has detected an electrical problem in the vent wax motor circuit. The fault can be caused by a loose wiring connection, a failed vent wax motor, a blown fuse on the control board, or a faulty vent drive circuit on the control board. Not all Kenmore dishwasher models include a vent wax motor, so this code only appears on equipped models.
How do I fix error code 10-2 on a Kenmore dishwasher?
Start by unplugging the dishwasher or turning off the circuit breaker. Use a multimeter to check the resistance of the vent wax motor and inspect all connectors in the vent circuit for looseness or corrosion. Also check the fuse on the control board that supplies the vent circuit. If the motor reads open (infinite resistance), replace the vent wax motor. If wiring and the motor test fine but the fuse is blown, replace the fuse or the control board depending on whether the fuse is serviceable separately on your model.
Is it safe to use my Kenmore dishwasher with error code 10-2 active?
Running the dishwasher with an active 10-2 code is not recommended. The vent wax motor controls the moisture release flap, and if it is not functioning, steam and excess moisture may not vent properly from the tub. This can affect drying performance and may allow moisture to build up in areas it should not reach. Diagnose and repair the fault before returning the unit to regular use.
How much does it cost to repair a Kenmore dishwasher error code 10-2?
If the fix is a loose wire connection, there is no parts cost, only your time. A replacement vent wax motor typically costs between $20 and $60 depending on the model. A replacement control board, which is the worst-case scenario, usually runs $80 to $200 or more for the part alone. Professional labor adds $100 to $200 on average. Starting with your own wiring inspection and motor resistance check can prevent unnecessary parts purchases.
How do I test the vent wax motor when diagnosing error code 10-2?
With the dishwasher unplugged, disconnect the wiring harness from the vent wax motor and place the probes of a multimeter set to resistance (ohms) across the motor terminals. A functioning wax motor will show a measurable resistance reading; an open motor will read OL or infinite resistance, confirming the motor has failed. Also check the resistance of each connector and wire segment in the vent circuit to rule out a break in the wiring before replacing the motor.
