GE Dishwasher Error Code SENSING_FLASH

SENSING_FLASH indicates a CleanSensor error, meaning the optical sensor that monitors wash water clarity is not producing or transmitting its sensing light during NORMAL or POTS & PANS cycles. The CleanSensor uses light to measure how dirty the water is so the cycle can adjust accordingly. When this light fails to illuminate, the control board registers the fault. Your dishwasher will continue to operate on fixed cycle timing without the sensor.

A reset may temporarily clear the fault display, but if the underlying cause such as a contaminated lens, failed sensor, or wiring fault is not corrected, the error will return the next time the dishwasher runs a NORMAL or POTS & PANS cycle. Start by cleaning the sensor lens in the tub before attempting a reset to see if contamination was the source of the problem.

Repair costs depend on the root cause. If cleaning the sensor lens resolves the issue, there is no parts cost involved. If the CleanSensor assembly needs replacement, parts and labor together typically range from around 100 to 250 dollars depending on your location and the specific model. If a main control board replacement is needed, total repair costs can run higher, often in the 200 to 400 dollar range.

Yes, the dishwasher is designed to keep running even with this error active. The CleanSensor is a cycle-optimization feature, and without it the machine simply runs its cycles for a fixed duration rather than adjusting based on water turbidity. Your dishes will still be cleaned. GE recommends scheduling a service call to restore full sensor function, but there is no need to stop using the appliance.

No, this error code does not indicate a safety hazard. It is limited to the optical CleanSensor circuit, which is a convenience and efficiency feature rather than a core wash or water-management system. The dishwasher's heating, water fill, drain, and pump functions are not affected by this fault.
