What 10-2 means on a Jenn-Air dishwasher

Error code 10-2 on a Jenn-Air dishwasher signals that the control board has detected an electrical problem in the vent wax motor circuit. Specifically, the board is reading an open circuit condition, meaning current is not flowing through the vent wax motor as expected. This is caused by either a loose or broken connection somewhere in the vent circuit wiring or a failed vent wax motor itself. Note that this code only applies to models equipped with a vent assembly.

The vent wax motor is a small actuator that opens a vent flap during the drying cycle, allowing moist air to escape the tub. When the motor or its wiring loses continuity, the control board cannot confirm the vent is operating, and it logs code 10-2 to flag the fault.

Diagnosing this code starts with disconnecting power and using a multimeter to check resistance across the vent wax motor terminals and at each connector in the vent circuit. A healthy wax motor will show a measurable resistance reading. An open reading (OL or infinite resistance) on the motor or at any connector pinpoints the failed component. Reconnecting loose terminals or replacing the faulty motor or wiring typically resolves the code.

Common causes of 10-2

  1. 01

    Open vent wax motor (internal failure)

    Part replacement

    The vent wax motor has failed internally, breaking the electrical circuit. A multimeter will read infinite resistance (OL) across the motor terminals, confirming it needs replacement.

  2. 02

    Loose or disconnected wiring connector in vent circuit

    Wiring / connection

    A connector in the vent wiring harness has come loose or pulled apart, interrupting current flow to the wax motor. Inspecting and reseating connectors in the vent circuit can resolve the code without replacing any parts.

  3. 03

    Broken or damaged vent circuit wiring

    Part replacement

    A wire in the vent harness has broken, chafed through, or corroded to the point of an open circuit. Visual inspection along the harness and continuity testing with a multimeter will identify the break, and the affected wire or harness section will need replacement.

  4. 04

    Faulty main control board

    Part replacement

    In rare cases where the vent motor and all wiring test within normal resistance ranges, the control board itself may be misreading the circuit. This is the least likely cause and should only be considered after fully verifying the motor and wiring are good.

Frequently asked questions about 10-2

What does error code 10-2 mean on a Jenn-Air dishwasher?
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.
How do I fix error code 10-2 on a Jenn-Air dishwasher?
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.
Can I still use my Jenn-Air dishwasher with a 10-2 error code active?
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.
How much does it cost to fix error code 10-2 on a Jenn-Air dishwasher?
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.
How do I test the vent wax motor to diagnose code 10-2?
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.
