What F10E2 means on a Kenmore dishwasher

The F10E2 error code on a Kenmore dishwasher indicates an electrical problem within the vent wax motor circuit. The vent wax motor is a thermally actuated component that opens and closes the dishwasher's drying vent, allowing moist air to escape during the drying cycle. When the control detects an abnormal electrical condition in this circuit, such as an open circuit, unexpected resistance reading, or a failed drive signal, it stores the F10E2 fault. This code is not present on all Kenmore dishwasher models, as some units do not use a vent wax motor assembly.

The most common electrical faults behind F10E2 include a loose or corroded wire connector in the vent circuit, an open (failed) wax motor coil, or a blown fuse in the vent circuit branch. The wax motor itself can fail internally, leaving the coil open and preventing the control board from completing the circuit. Connectors in dishwasher environments are exposed to heat and humidity, which accelerates corrosion and causes intermittent or complete connection failures over time.

Diagnosis requires disconnecting power to the unit before performing resistance checks on the wax motor and inspecting all connectors and wiring in the vent circuit. A properly functioning wax motor will show a measurable resistance value across its terminals; an open motor will show infinite resistance (OL on a multimeter). The fuse associated with the vent circuit should also be tested for continuity. If wiring, connectors, and the fuse all check out, the vent drive circuit on the control board itself may be the source of the fault.

Common causes of F10E2

  1. 01

    Loose or corroded wire connector in the vent circuit

    Wiring / connection

    Connectors in the vent circuit can loosen or corrode due to repeated heat and moisture exposure. Inspect all connectors between the control board and the vent wax motor for corrosion, bent terminals, or poor seating.

  2. 02

    Open vent wax motor coil

    Part replacement

    The wax motor coil can fail internally, resulting in an open circuit. Testing the motor with a multimeter will show infinite resistance across the terminals if the coil has failed, requiring motor replacement.

  3. 03

    Blown fuse in the vent circuit

    Part replacement

    A fuse protecting the vent circuit branch may have opened due to an overcurrent event or a failing motor. Test the fuse for continuity and replace it if it shows no continuity.

  4. 04

    Faulty vent drive circuit on the control board

    Part replacement

    If the wax motor, fuse, and all wiring connections test correctly, the drive circuit on the main control board responsible for powering the vent motor may have failed. This would require control board replacement.

Frequently asked questions about F10E2

What does F10E2 mean on a Kenmore dishwasher?
F10E2 indicates an electrical problem in the vent wax motor circuit. This includes a loose connection in the vent wiring, an open vent wax motor coil, a blown fuse in the vent circuit, or a faulty vent drive circuit on the control board. Not all Kenmore dishwasher models are equipped with a vent wax motor, so this code may not apply to every unit.
How do I fix the F10E2 error code on my Kenmore dishwasher?
Start by unplugging the dishwasher or shutting off its circuit breaker. Then inspect all wire connectors in the vent circuit for corrosion or loose terminals, and use a multimeter to check the resistance of the vent wax motor. Also test the vent circuit fuse for continuity. Replace any component that fails its electrical test, such as the wax motor or fuse, before suspecting the control board.
Is it safe to use my Kenmore dishwasher while the F10E2 code is active?
It is generally not recommended to continue running the dishwasher with an active fault code. A failed vent wax motor means the drying vent may not be opening properly, which can result in poor drying performance and potential moisture buildup inside the unit. Resolving the fault before continued use is the safer approach.
How much does it cost to repair a Kenmore dishwasher with an F10E2 error?
Repair costs depend on the specific failed component. A replacement vent wax motor typically ranges from $25 to $75 for the part. If the main control board is at fault, parts alone can range from $100 to $250 or more. Adding professional labor costs generally brings the total repair estimate to between $100 and $400 depending on the fault and your location.
Will resetting my Kenmore dishwasher clear the F10E2 error code?
A power reset may temporarily clear the code, but F10E2 will return if the underlying electrical fault in the vent circuit is still present. A reset does not repair a failed wax motor, blown fuse, or corroded connector. Proper diagnosis and repair of the faulty component is required to permanently resolve the code.
