What F24 means on a KitchenAid range

The F24 error code on a KitchenAid range indicates that the drain button has become electrically disconnected from the steam board. The steam board is a dedicated control board that manages steam-related functions in the range, and the drain button communicates with it through connector JP02. When this connection is interrupted or absent, the steam board cannot detect the state of the drain button, triggering the F24 fault.

The most direct cause of this error is a loose, corroded, or fully disconnected wiring harness at the JP02 connector on the steam board. Connectors can work loose over time due to vibration, thermal cycling, or improper reassembly after a previous repair. In some cases, the wiring harness itself may have damaged conductors or a broken connector tab that prevents secure seating at JP02.

A failed drain button is also a possible cause. If the button's internal contacts have broken or the button assembly has physically failed, it may present as an open circuit to the steam board, which the control interprets as a disconnection. Before replacing any components, the first diagnostic step is to disconnect power to the range and inspect the JP02 connector on the steam board for proper seating, visible damage, and secure contact with the harness terminals.

Common causes of F24

  1. 01

    Loose or disconnected JP02 connector

    Wiring / connection

    The wiring harness at connector JP02 on the steam board may have worked loose or pulled free entirely. Inspecting and firmly reseating this connector is the first step after disconnecting power.

  2. 02

    Damaged wiring harness

    Part replacement

    The wire harness leading from the drain button to the steam board may have broken conductors, pinched wiring, or a cracked connector housing that prevents reliable contact. A visual inspection along the full length of the harness will help identify damage.

  3. 03

    Corroded or dirty connector terminals

    Wiring / connection

    Moisture or grease exposure in the range can cause oxidation on the JP02 connector terminals, increasing resistance and breaking the electrical signal between the drain button and the steam board.

  4. 04

    Failed drain button

    Part replacement

    The drain button itself may have failed internally, presenting an open circuit to the steam board. If the connector and harness check out, the button assembly should be tested for continuity and replaced if faulty.

  5. 05

    Faulty steam board

    Part replacement

    If all wiring and the drain button test correctly, the steam board itself may have a defect at the JP02 connection port or in the circuitry that monitors the drain button input.

Frequently asked questions about F24

What does F24 mean on a KitchenAid range?
F24 means the steam board has detected that the drain button is electrically disconnected. The steam board uses connector JP02 to communicate with the drain button, and this code appears when that connection is missing or broken. It can be caused by a loose harness connector, damaged wiring, a failed button, or a faulty steam board.
Can I fix the F24 error myself?
In many cases, yes. Start by unplugging the range or shutting off its circuit breaker, then locate the steam board and check the JP02 connector for a secure fit. If the connector is loose, reseating it may clear the fault. If the wiring or button is damaged, those repairs may require ordering replacement parts.
Is it safe to use my KitchenAid range while the F24 code is showing?
It is generally best to avoid using the steam functions while this fault is active, as the steam board cannot reliably detect the state of the drain button. Whether other cooking functions are affected depends on your specific model. When in doubt, resolve the fault before resuming use.
Will resetting the range clear the F24 error code?
A power reset may temporarily clear the code, but if the underlying connection problem still exists, the fault will return. The code will only stay cleared once the disconnection at JP02 or the drain button itself is properly diagnosed and repaired.
How much does it cost to repair a KitchenAid range F24 error?
If the fix is simply reseating the JP02 connector, there may be no parts cost at all. A replacement wiring harness or drain button typically runs in the range of $20 to $80 in parts. If the steam board itself needs replacement, parts alone can range from $100 to $300 or more, with additional labor costs if a technician is needed.
