What F24 means on a GE dishwasher

The F24 error code on a GE dishwasher indicates a failure associated with the circulation pump. The circulation pump is the core component responsible for drawing water from the sump and pressurizing it through the spray arms during wash and rinse cycles. When the control board detects that the circulation pump is not performing within expected parameters, whether due to an electrical fault, mechanical seizure, or winding failure, it triggers the F24 code and halts the cycle to prevent further damage.

The first diagnostic step when F24 appears is to inspect the wire harness connected to the circulation pump. Damaged, corroded, or loose terminals can interrupt the signal between the control board and the pump motor, mimicking a pump failure when the pump itself may still be functional. Technicians should check the harness for any signs of chafing, heat damage, or connector corrosion before condemning the pump.

If the wire harness inspects cleanly and connections are secure, the circulation pump itself is the likely cause and should be replaced. Pump failures can result from worn motor windings, a seized impeller due to debris accumulation, or bearing failure over time. Because the pump is a sealed unit in most GE dishwasher configurations, internal repairs are not practical and full pump replacement is the standard corrective action when the harness has been ruled out.

Common causes of F24

  1. 01

    Failed circulation pump motor

    Part replacement

    The pump motor windings can burn out or the motor can seize over time, preventing it from running. This is the most common cause of F24 and typically requires full pump replacement.

  2. 02

    Loose or damaged wire harness connection

    Wiring / connection

    Corroded, chafed, or disconnected wiring between the control board and the circulation pump can trigger F24 even if the pump motor itself is still functional. Inspect all connectors at the pump and trace the harness for damage.

  3. 03

    Seized pump impeller due to debris

    Wiring / connection

    Hard debris such as broken glass, seeds, or food buildup can jam the pump impeller and cause the motor to stall. Checking and clearing the sump area and pump inlet should be part of the initial diagnosis.

  4. 04

    Corroded pump terminals

    Wiring / connection

    Moisture intrusion at the pump electrical connector can cause corrosion that increases resistance in the circuit, disrupting normal pump operation and triggering the fault code.

Frequently asked questions about F24

What does F24 mean on a GE dishwasher?
F24 on a GE dishwasher indicates a circulation pump fault. The control board has detected that the circulation pump, which pressurizes water through the spray arms, is not operating correctly. The dishwasher will stop the cycle until the issue is resolved. The problem may be a failed pump motor or a wiring issue in the harness connecting the pump to the control board.
Can I fix the F24 error code myself?
A knowledgeable DIYer can start by checking the wire harness and connectors at the circulation pump for damage, corrosion, or loose terminals. If the harness looks intact, the next step is replacing the circulation pump, which involves disconnecting the power supply, accessing the pump from underneath or the front of the dishwasher, and installing a compatible replacement unit. If you are not comfortable working with appliance wiring or disassembling the dishwasher, a professional technician is recommended.
Is it safe to keep using my dishwasher with the F24 code showing?
No, you should not continue running the dishwasher while the F24 code is active. The code indicates the circulation pump is not functioning, which means the machine cannot properly wash or rinse dishes. Running cycles in this condition could stress other components without any benefit and will not clear the fault.
How much does it cost to fix a GE dishwasher F24 error?
If only a wire harness repair or connector cleaning is needed, the cost is typically minimal, covering a service call and a small amount of labor. If the circulation pump itself needs replacement, parts and labor combined can range from roughly $150 to $350 or more, depending on your location and the specific dishwasher model. Getting a diagnosis before committing to repair can help determine whether the repair is cost-effective relative to the age of the appliance.
Will resetting my GE dishwasher clear the F24 error code?
A reset may temporarily clear the F24 code from the display, but it will return as soon as the dishwasher attempts to run a cycle and the control board detects the pump fault again. Resetting does not address the underlying cause, which is either a wiring problem or a failed circulation pump. A proper repair of the faulty component is required to permanently resolve the error.
