Jenn-Air Dishwasher Error Code Extra Rinse LED + Clean LED

When the Extra Rinse LED and Clean LED illuminate together on a Jenn-Air dishwasher, it signals a turbidity sensor failure detected during the Field Service Test. The turbidity sensor monitors wash water clarity to help the dishwasher optimize its cycle. This LED combination is the dishwasher's way of reporting that the sensor is not functioning within expected parameters. A technician should run the Field Service Test to confirm the fault before proceeding with diagnostics.

A power reset may temporarily clear the displayed LEDs, but it will not fix the underlying turbidity sensor problem. If the sensor or wiring fault is still present, the error will return the next time the Field Service Test is run or the dishwasher attempts a wash cycle. Proper diagnosis and repair of the sensor or its wiring is required for a lasting fix.

Repair costs depend on the root cause. If the sensor only needs cleaning, the cost is primarily a service call fee, typically in the range of $75 to $150. Replacing the turbidity sensor itself usually adds $50 to $120 in parts. If the control board is found to be at fault, parts and labor combined can range from $200 to $450 or more depending on the specific board and labor rates in your area.

Start by running the Field Service Test to confirm the fault is active. Then inspect the turbidity sensor for grease or mineral deposits and clean it if needed, since contamination is a common cause. Next, check the wiring harness and connectors for continuity and corrosion. If the sensor and wiring both check out, the sensor itself may need to be replaced.

The dishwasher may still complete cycles with a turbidity sensor fault, but it will not be able to accurately monitor water clarity or adjust cycle parameters based on soil level. This can result in less effective cleaning or inefficient water use. It is best to have the issue diagnosed and repaired rather than continuing to run the unit with a known sensor fault.
