Jenn-Air Dishwasher Error Code 10-2

Code 10-2 means the control board has detected an electrical problem in the vent wax motor circuit, specifically an open circuit condition. This applies only to Jenn-Air dishwasher models equipped with a vent assembly. The cause is either a loose connection in the vent wiring or a failed vent wax motor that has lost internal continuity.

The dishwasher may still run wash cycles with code 10-2 active, but the vent wax motor will not function correctly, which means moist air cannot escape the tub during drying. This results in poor drying performance and can lead to excess moisture buildup inside the dishwasher over time. Continued use is not recommended until the fault is repaired.

Disconnect power to the dishwasher, then locate the vent assembly and unplug the wax motor connector. Set a multimeter to the resistance (ohms) setting and probe the two terminals on the wax motor. A working motor will show a finite resistance reading, typically in the range specified in your model's service documentation. An OL or infinite reading confirms the motor is open and needs replacement. Also test each connector in the circuit for continuity to rule out a wiring fault before ordering parts.

Start by unplugging the dishwasher or shutting off the circuit breaker. Locate the vent assembly and use a multimeter to test resistance across the vent wax motor terminals and check each connector in the vent circuit for continuity. If a connector is loose, reseat it and retest. If the wax motor reads open (OL on a multimeter), replace the motor. If wiring is broken or corroded, replace the affected section of harness. Professional help is advisable if you are not comfortable working with appliance wiring.

If the fix is simply reseating a loose connector, there is no parts cost. A replacement vent wax motor typically costs between $20 and $60 depending on the model. If you hire a technician, expect to add $100 to $200 in labor. DIY repair is manageable for anyone comfortable with a multimeter and basic appliance disassembly, since the wax motor is generally accessible without major teardown.
