Maytag Dishwasher Error Code Extra Rinse LED flash

The Extra Rinse LED flash indicates that a turbidity sensor failure was detected during the Field Service Test. The turbidity sensor monitors water clarity to help the dishwasher adjust its wash cycle. This code points to a problem with the sensor itself, its wiring, or the control board's ability to read the sensor signal. A technician should run the Field Service Test and then the Manual Function Test to isolate the exact cause.

A turbidity sensor fault means the dishwasher cannot properly monitor water clarity, so cycle performance may be compromised. The machine may not clean dishes as effectively without accurate sensor input. It is best to address the fault before relying on the dishwasher for regular use, though the condition does not typically present a safety hazard.

A basic power reset may temporarily clear the displayed fault, but it will not resolve the underlying turbidity sensor issue. If the sensor or related components are actually faulty, the code will return during the next Field Service Test or normal operation. A proper diagnosis and component-level repair are necessary to permanently resolve this fault.

Start by running the Field Service Test to confirm the fault, then use the Manual Function Test to check individual components. Inspect the turbidity sensor lens for contamination and clean it if needed. If cleaning does not resolve the issue, the sensor, wiring harness, or main control board may need to be replaced depending on what diagnostic testing reveals.

Repair costs vary depending on the root cause. A turbidity sensor replacement typically falls in the range of $50 to $150 for the part, while a main control board can range from $100 to $300 or more. Adding professional labor will increase the total cost, so getting a diagnostic assessment first helps determine the most cost-effective path forward.
