i60Frigidaire Dishwasher — Frigidaire Dishwasher i60 Error Code

The i60 code means the dishwasher's heating element failed to raise the water temperature to the target level within the allotted time. The heating element sits at the bottom of the tub and heats wash water to improve cleaning effectiveness and sanitization. When it fails (open circuit), water temperatures stay low, dishes are not sanitized, and detergent may not dissolve properly. This code can also be caused by a faulty water temperature sensor (thermistor) that misreports water temperature to the control board.

Unplug the dishwasher and access the heating element terminals at the bottom of the tub. Test the element with a multimeter — a working element reads 15–30 ohms; an open circuit (OL) confirms failure. Replace the element if failed. Also test the water temperature sensor (thermistor) in the sump for correct resistance at known temperatures. If both element and sensor test good, the relay on the control board that switches power to the element may have failed — in this case, control board (5304517465) replacement is needed.
