What F231 means on a GE dishwasher

The F231 error code on a GE dishwasher indicates that a CSM (Current Sense Module) trip has been detected. The CSM is a protective component that monitors electrical current flowing through the dishwasher's motor circuit. When current exceeds a safe threshold, the CSM trips to prevent damage to the motor, wiring, or control board. This is a protective event, not simply a sensor fault, meaning the underlying cause of the overcurrent condition must be identified and resolved before the dishwasher can operate safely.

A CSM trip can result from a mechanical obstruction in the wash or drain motor, a failing motor drawing excessive current, or a wiring fault such as a short circuit or damaged harness. In some cases, a worn pump bearing or a seized impeller can cause the motor to work harder than normal, pulling enough current to trigger the trip. Moisture ingress into electrical connections can also create intermittent short conditions that cause the CSM to activate.

Diagnosis requires following the CSM diagnostics procedure specific to the GE dishwasher platform. This typically involves inspecting the motor and pump assembly for mechanical binding, checking wiring harnesses for chafing or shorts, and verifying that the CSM module itself has not failed internally. Simply resetting the error without identifying the trip cause will likely result in the code returning and could allow conditions that further damage the motor or electrical system.

Common causes of F231

  1. 01

    Wash or drain motor mechanical obstruction

    Wiring / connection

    Debris such as broken glass, food particles, or a foreign object lodged in the pump impeller can cause the motor to draw excessive current and trip the CSM. Inspect the pump housing and impeller for blockages.

  2. 02

    Failing or seized motor

    Part replacement

    A wash pump or drain pump motor with worn bearings or a failing winding can pull more current than normal, triggering a CSM trip. The motor may produce unusual noise or fail to spin freely when tested.

  3. 03

    Wiring harness short circuit or damage

    Part replacement

    Chafed, pinched, or corroded wiring in the motor circuit can create a partial or complete short that causes overcurrent. Inspect the harness routing from the control board to the motor for visible damage.

  4. 04

    Moisture or water intrusion in electrical connections

    Wiring / connection

    Water leaking onto motor connectors or the CSM module itself can create an unintended current path and trigger a trip. Check connector housings and the module area for signs of moisture or corrosion.

  5. 05

    Failed CSM module

    Part replacement

    In some cases the CSM module itself may have failed internally, causing it to trip even when current levels are within normal range. This is typically diagnosed after all other causes have been ruled out.

Frequently asked questions about F231

What does F231 mean on a GE dishwasher?
F231 means the dishwasher's Current Sense Module (CSM) has detected an overcurrent condition and tripped to protect the motor and electrical system. It is a protective fault, similar to a circuit breaker, that stops operation when current exceeds a safe level. The root cause of the trip must be identified and corrected before the dishwasher will operate normally again.
Can I fix the F231 error myself?
Some causes, such as a clogged pump impeller or a visibly damaged wiring connector, can be addressed by a knowledgeable DIYer with basic appliance repair experience. However, diagnosing a failing motor or a faulty CSM module requires electrical testing and familiarity with the CSM diagnostics procedure for GE dishwashers. If you are not comfortable working with appliance electrical components, a qualified technician should perform the diagnosis.
Is it safe to keep using my dishwasher with the F231 error?
No, you should not continue running the dishwasher until the cause of the CSM trip is identified and repaired. The CSM tripped because an unsafe electrical condition was detected, and operating the appliance without resolving that condition risks further damage to the motor, wiring, or control board. In worst-case scenarios involving electrical faults, continued operation could create a safety hazard.
How much does it cost to repair a GE dishwasher F231 error?
Repair costs vary depending on the cause. Clearing a pump obstruction is generally low cost if done without a service call. Replacing a drain or wash pump motor typically falls in the range of $150 to $350 including parts and labor. If the control board or CSM module requires replacement, costs can range from $200 to $450 or more, depending on parts availability and labor rates in your area.
Will resetting the dishwasher clear the F231 error code?
A reset may temporarily clear the F231 code, but the error will return if the underlying cause of the CSM trip has not been resolved. Because this code indicates a real overcurrent event rather than a simple sensor glitch, a reset alone is not a fix. The CSM diagnostics procedure should be followed to identify and correct the trip cause before resuming normal use.
