GE Dishwasher Error Code 97

Code 97 on a GE dishwasher with a 3-digit display indicates that the turbidity sensor has failed during the service mode auxiliary pump test. The turbidity sensor monitors water clarity so the dishwasher can adjust its wash cycle based on how dirty the water is. When this sensor stops functioning correctly, the control board logs code 97 and the sensor typically needs to be replaced. Checking the wiring connections first is recommended before swapping the part.

Resetting the dishwasher will not permanently clear code 97 because the error is tied to an actual hardware failure detected during a diagnostic test. The code will return when the service mode test is run again as long as the underlying sensor or wiring problem remains unresolved. The turbidity sensor or its wiring must be repaired or replaced to clear the fault.

If the issue is simply a loose or corroded wiring connection, the cost can be minimal, covering only your time or a small amount for electrical contact cleaner or a connector repair. If the turbidity sensor itself needs replacement, the part typically costs in the range of $20 to $60 depending on the model, plus any labor charges if a technician performs the work. Professional diagnostic and repair visits generally run between $100 and $200 or more depending on your location.

A knowledgeable DIYer can address this repair by first inspecting the wiring harness and connector at the turbidity sensor for loose terminals or corrosion. If the wiring looks intact, the next step is replacing the turbidity sensor. The sensor is typically located in the sump area of the dishwasher, and replacement requires disconnecting the unit from power before beginning any work.

Error code 97 does not represent an immediate safety hazard such as a water leak or electrical fault, but running the dishwasher with a failed turbidity sensor means the control system cannot accurately gauge water dirtiness. This can result in poor cleaning performance or abnormal cycle behavior. It is best to address the repair before continuing regular use.
