Cove Dishwasher Error Code 550147

Error code 550147 means the turbidity sensor, identified as AE1/2 in the system, is producing a signal outside its valid operating limits. This sensor monitors wash water clarity to help the dishwasher manage its cycle. The fault is most often caused by a dirty or coated sensor lens rather than a failed component. Cleaning the sensor is the recommended first step before further diagnosis.

Error 550147 is a sensor fault, not an electrical or water safety hazard, so there is no immediate danger to operating the dishwasher. However, with the turbidity sensor out of range, the machine cannot accurately assess water cleanliness, which may result in suboptimal wash performance. It is best to address the fault promptly to ensure proper cycle operation.

If the issue is simply a dirty sensor, the repair cost is minimal and limited to your time or a basic service call fee. If the turbidity sensor needs replacement, parts and labor combined typically range from around $100 to $300 depending on your location and service provider. Control board replacement, if ever needed, would cost significantly more and should only be considered after all other causes are ruled out.

Start by locating the turbidity sensor at the bottom of the dishwasher tub and cleaning it carefully to remove any grease, food debris, or mineral scale. After cleaning, run a test cycle to see if the error clears. If the code returns, inspect the sensor's wiring connector for damage or corrosion, and if those check out, the sensor itself may need to be replaced.

A reset may temporarily clear the error code, but if the underlying cause such as a dirty or faulty sensor is not addressed, the code will return once the dishwasher runs a cycle and the control board checks the sensor signal again. Cleaning the sensor or repairing the wiring is necessary for a lasting fix.
