Kenmore Dishwasher Error Code 10-2

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.

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.

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.

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.

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.
