during the drying cycle, drops to 700 W for gentler drying.

Water inlet temperature must be at least 120 °F for proper drying. Low water inlet temperature will prevent proper convection air movement and increase drying time substantially.

If the complaint is the dishes are not drying cor- rectly, don’t overlook the rinse agent. A rinse agent will improve the water sheeting action and drying performance.

Replacement

Note: The heating element nuts are located on the underside of the washer, near the back. Ample force is required to remove the nuts. Removing the dishwasher from installation may be required.

1.Disconnect power and remove wire leads from heating element.

2.Unscrew 2 heating element nuts.

3.Remove 2 screws, 2 heating element supports, and the heating element.

Turbidity Sensor

The turbidity sensor measures the amount of suspended particles in the wash water in the sump. As the sump water lays between the 1/4- to 3/8- inch gap between the LED transmitter and the receptor during the first fill, the baseline reading is taken. Successive turbidity measurements are supplied to the control module and used to deter- mine whether any prewash or rinse cycles can be skipped. Decisions are based on a comparison of clean water measurements at the beginning of the first fill, measurements taken at selected fills, and water temperature. By measuring the turbidity level, the control module can conserve energy on lightly soiled loads by skipping unnecessary cycles.

Note: If the turbidity sensor circuit fails open or shorted, the sensing LED on the control panel will not light and the unit will operate for the maximum amount of time, using the maximum number of wash and rinse fills for the selected cycle.

The turbidity sensor also contains the thermisteor for automatic temperature control.

Turbidity Sensor Test

Factory test mode is the most accurate way to test the turbidity sensor circuit (circuit contains control module, wiring, and turbidity sensor). Refer to the Factory Test Mode chapter.
