Cove Dishwasher Error Code 550196

Error code 550196 means the turbidity sensor, designated AE1/2 in the wiring circuit, was unable to complete its calibration routine. This sensor measures how cloudy or clear the wash water is so the dishwasher can optimize the cycle. The fault is most often caused by a dirty or fouled sensor optical window. Cleaning the sensor is the recommended first diagnostic step.

Error code 550196 does not indicate a water leak, electrical hazard, or heating system failure, so it is not an immediate safety risk. However, when the turbidity sensor cannot calibrate, the dishwasher may not be able to properly adjust the wash cycle for soil levels, which can result in dishes that are not fully cleaned. It is best to address the fault promptly to ensure the appliance operates as intended.

If the fix is simply cleaning the turbidity sensor, the cost is minimal and can often be done as a DIY task with no parts required. If the sensor assembly needs to be replaced, parts and labor costs typically range from around $100 to $300 or more depending on parts pricing and local labor rates. Wiring harness repairs fall somewhere in between depending on the extent of the damage.

Start by locating the turbidity sensor inside the dishwasher tub, typically near the sump area, and carefully clean its optical window to remove grease, scale, or food debris. After cleaning, run a test cycle to see if the error clears. If the code returns, check the sensor's wiring harness and connector at the AE1/2 port for corrosion or loose connections. If the wiring is intact and the error persists, the sensor assembly itself may need to be replaced.

A power reset may temporarily clear the stored fault code, but it will not resolve the underlying cause. If the turbidity sensor is still dirty or faulty, the error will return as soon as the dishwasher attempts to calibrate the sensor again during the next cycle. A reset should only be used after the actual cause has been identified and corrected.
