What F146 means on a GE dishwasher

The F146 error code on a GE dishwasher indicates a circulation pump fault. The circulation pump is the primary component responsible for drawing water from the sump and forcing it through the spray arms during the wash and rinse cycles. When the control board detects an abnormal electrical or mechanical condition from this pump, it triggers F146 and halts the cycle to prevent damage.

The most common electrical causes involve the wiring harness connecting the control board to the circulation pump motor. Damaged, corroded, or loose connector pins can interrupt the signal or power delivery to the pump, causing the board to register a fault even if the pump itself is functional. Inspecting the harness for pinched wires, burnt connectors, or terminals that have worked loose is the recommended first step before condemning the pump.

If the harness checks out and shows no visible damage or continuity issues, the circulation pump itself is likely at fault. Internal motor failure, a seized impeller, or a burned-out winding inside the pump assembly can all produce this error. In these cases, the pump must be replaced as a complete unit. Because the pump handles water under pressure, any failure left unaddressed can also lead to incomplete wash cycles, poor cleaning performance, or water remaining in the tub.

Common causes of F146

  1. 01

    Loose or damaged wiring harness

    Wiring / connection

    The connector or wiring between the control board and circulation pump can loosen, corrode, or sustain damage over time. Inspect all terminals and connectors along the harness for corrosion, burn marks, or pins that have backed out of their housing.

  2. 02

    Failed circulation pump motor

    Part replacement

    The internal windings of the circulation pump motor can burn out or short, causing the control board to detect an out-of-range electrical condition. If the harness tests good, the pump motor is the next suspect and will need to be replaced.

  3. 03

    Seized pump impeller

    Wiring / connection

    Debris such as broken glass, food particles, or small utensils can jam the pump impeller, preventing it from spinning and causing the motor to draw excessive current. Check the sump area for obstructions before assuming the pump itself has failed internally.

  4. 04

    Corroded or damaged connector pins

    Wiring / connection

    Even without full wire damage, individual pins in the pump harness connector can corrode or deform, creating an intermittent or open circuit. Cleaning or replacing the connector can resolve the fault without a full pump replacement.

  5. 05

    Control board fault

    Part replacement

    In rare cases, the control board itself may incorrectly interpret pump signals and trigger F146 even when the pump and harness are functioning correctly. This is typically only considered after all other components have been tested and confirmed good.

Frequently asked questions about F146

What does F146 mean on a GE dishwasher?
F146 on a GE dishwasher indicates a circulation pump error. The dishwasher's control board has detected a fault in the pump responsible for moving water through the spray arms during the wash cycle. The cycle stops to prevent further damage. Diagnosis starts with inspecting the pump wiring harness and, if needed, replacing the pump.
Can I fix the F146 error myself?
Some causes of F146 are DIY-friendly, particularly checking and reseating the wiring harness or clearing a jammed impeller. If the pump motor itself has failed, replacing it requires disconnecting water supply lines and electrical connections, which is manageable for a skilled DIYer with appliance repair experience. If you are not comfortable working around wiring and plumbing connections, a qualified technician is recommended.
Will resetting my GE dishwasher clear the F146 error?
Resetting the dishwasher may temporarily clear the F146 code, but the error will return if the underlying problem with the circulation pump or its harness has not been resolved. A reset is useful for confirming whether a fault was intermittent, but it is not a fix. The root cause must be diagnosed and corrected to permanently clear the code.
Is it safe to use my dishwasher while F146 is displayed?
It is not recommended to continue running the dishwasher while F146 is active. The error indicates the circulation pump is not operating correctly, meaning dishes will not be washed properly and the unit may sustain further damage if the fault involves an electrical issue such as a short or overloaded motor circuit. The dishwasher should remain out of service until the cause is identified and repaired.
How much does it cost to repair the F146 error on a GE dishwasher?
Repair costs vary depending on the root cause. If the fix involves only reseating or repairing the wiring harness, costs may be minimal, primarily labor if a technician is involved. A replacement circulation pump typically costs between $80 and $200 for the part alone, with professional labor adding $100 to $200 on top of that depending on your location. Diagnosing the harness first before replacing the pump can help avoid unnecessary parts costs.
