GE Dishwasher Error Code Clean LED

On a GE dishwasher, the Clean LED flashing as an error code means the control board has detected a short circuit or open circuit at the turbidity sensor. The turbidity sensor monitors water clarity during the wash cycle. When the control reads an abnormal electrical signal from this sensor, it stops trusting the sensor data and logs the fault. This is different from the Clean LED simply indicating a finished cycle.

Running the dishwasher with this error active is not recommended for regular use. Without a functioning turbidity sensor signal, the control board cannot accurately adjust the wash cycle based on water clarity, which can result in poorly cleaned dishes or cycles that do not complete correctly. The underlying wiring issue could also worsen with repeated use. Address the fault before relying on the dishwasher for normal loads.

The exact key sequence for entering Error Code Mode varies by GE model, but it commonly involves pressing a specific combination of cycle or option buttons in succession with the door closed. Check the service manual or tech sheet for your specific model number, which is usually located on the inner door edge. Once in diagnostic mode, the control will display stored fault codes from the last five cycles, confirming whether the turbidity sensor fault has occurred repeatedly or just once.

Start by entering Error Code Mode to confirm the fault is stored in the cycle history, which distinguishes a real recurring fault from a one-time glitch. Next, inspect the wiring harness connector at the turbidity sensor for corrosion, broken pins, or disconnection and reseat it firmly. If the wiring looks intact, test the turbidity sensor for correct resistance or continuity. A sensor that reads open or shorted needs to be replaced. If the sensor and wiring both check out, the control board may need replacement.

If the fix is simply reseating a loose wiring connector, there is no parts cost. A replacement turbidity sensor typically costs between $20 and $60 depending on the model. If the control board is the root cause, board replacement usually runs $100 to $250 for the part. Professional labor adds $75 to $150 per hour in most markets. Checking and reseating the wiring harness yourself before ordering parts is a reasonable first step for a DIY homeowner.
