GE Dishwasher Error Code 888

The 888 code means the Current Sense Module (CSM) has tripped due to a detected electrical fault, leaving the dishwasher completely non-responsive. It will display on the panel until the CSM is reset. The code itself does not identify the specific failed component, so further diagnosis is required after resetting. Simply clearing the code without fixing the root cause will result in it returning.

You should not continue using the dishwasher until the cause of the CSM trip has been identified and corrected. The CSM tripped because it detected an abnormal current condition, which can indicate a serious electrical fault such as a short circuit or a failing motor. Running the unit before resolving the underlying issue risks additional damage to the control board or wiring.

A knowledgeable DIYer can perform the power cycle reset and inspect visible wiring for obvious damage. However, diagnosing the specific component that caused the CSM to trip requires testing motors, pumps, and the heating element for electrical faults, which involves working with internal wiring and using a multimeter. If you are not comfortable with electrical diagnostics, a qualified technician should handle the repair.

Yes, cycling the power at the circuit breaker or entering Service Mode will reset the CSM and clear the 888 display. However, if the underlying electrical fault is still present, the CSM will trip again once the dishwasher attempts to operate. A reset should always be followed by a full diagnostic inspection of the motor, pump, heating element, and wiring.

Repair costs depend entirely on which component caused the CSM to trip. A wiring harness repair may cost between $75 and $200 in parts and labor, while replacing a wash motor or control board can range from $150 to $400 or more. A service call to diagnose the root cause is strongly recommended before purchasing any parts.
