What F10E3 means on a Kenmore dishwasher

The F10E3 error code on a Kenmore dishwasher indicates a drying fan fault. This code applies only to models equipped with a powered drying fan, which is used to circulate heated air during the drying cycle and improve drying performance. When the control board detects an abnormal condition in the fan circuit, such as an open circuit, loss of continuity, or a failure in the fan drive circuitry, it triggers the F10E3 code and may halt or limit the drying cycle.

The most common causes fall into two categories: a mechanical or electrical failure in the fan motor itself, or a wiring issue in the circuit connecting the fan motor to the control board. An open fan motor means the motor's internal windings have failed, resulting in infinite resistance when measured across the motor terminals. A loose or corroded connection anywhere in the fan circuit can produce the same symptom by interrupting current flow. The fan drive circuit on the control board can also fail, meaning the board cannot properly energize or monitor the motor.

Diagnosis begins with the dishwasher fully unplugged or disconnected from power. A technician should measure resistance across the fan motor terminals and check all wiring connectors in the fan circuit for continuity, corrosion, or physical damage. Normal motor resistance values should be finite and consistent with the motor's specifications. If resistance is infinite, the motor has an open winding and needs replacement. If wiring and motor check out, the fault likely lies in the fan drive circuit on the control board.

Common causes of F10E3

  1. 01

    Loose or disconnected wiring in fan circuit

    Wiring / connection

    A connector that has vibrated loose or a wire that has separated from its terminal can interrupt the fan circuit and trigger F10E3. Inspect all connectors between the fan motor and the control board for secure seating and signs of corrosion or burn marks.

  2. 02

    Open fan motor winding

    Part replacement

    Internal motor windings can fail over time, resulting in an open circuit with infinite resistance when measured across the motor terminals. This requires fan motor replacement.

  3. 03

    Corroded or damaged connector terminals

    Wiring / connection

    Moisture inside the dishwasher can corrode connector pins in the fan circuit, increasing resistance to the point where the control board registers a fault. Check each connector carefully for green or white corrosion deposits and damaged pins.

  4. 04

    Faulty fan drive circuit on the control board

    Part replacement

    If the motor and all wiring check out with normal resistance values and solid continuity, the fan drive circuit on the main control board may have failed. This prevents the board from properly powering or monitoring the fan motor and typically requires control board replacement.

  5. 05

    Failed fan motor due to mechanical seizure

    Part replacement

    The fan motor can seize mechanically if debris enters the fan housing or the motor bearings wear out. A seized motor may show correct resistance readings but will not spin freely when rotated by hand.

Frequently asked questions about F10E3

What does F10E3 mean on a Kenmore dishwasher?
F10E3 indicates a drying fan error on Kenmore dishwashers equipped with a powered drying fan. The control board has detected a problem in the fan circuit, which could be a loose wiring connection, an open fan motor winding, or a failure in the fan drive circuit on the control board. This code will only appear on models that include a drying fan as part of their drying system.
How do I fix the F10E3 error on my Kenmore dishwasher?
Start by unplugging the dishwasher or disconnecting it from power at the breaker. Then locate the drying fan motor and measure its resistance with a multimeter. Also check every wiring connector in the fan circuit for looseness, corrosion, or damage. If the motor shows infinite resistance, it needs to be replaced. If the motor and wiring are fine, the control board's fan drive circuit is likely at fault.
Is it safe to keep using my dishwasher with an F10E3 error?
The dishwasher may continue to run wash and rinse cycles even with an F10E3 error, but drying performance will be reduced or absent. There is no immediate safety hazard from a failed drying fan. However, it is best to diagnose and repair the fault promptly to restore full functionality and prevent any wiring issue from worsening.
Will resetting my Kenmore dishwasher clear the F10E3 error code?
A reset may temporarily clear the F10E3 code, but if the underlying fault in the fan circuit still exists, the code will return when the dishwasher runs through its drying cycle again. The error code will only clear permanently once the actual problem, whether a loose connection, failed motor, or faulty control board circuit, is identified and corrected.
How much does it cost to repair an F10E3 error on a Kenmore dishwasher?
Repair costs vary depending on the root cause. If the fix is simply reseating a loose connector, there may be no parts cost involved. A replacement drying fan motor typically costs in the range of $30 to $80 for the part. If the control board requires replacement, parts alone can range from $100 to $250 or more, with additional labor costs if a technician performs the repair.
