Heating Element

The heating element can be activated using Service Mode.

The dual-wattage heating element produces 875 watts during wash, to help heat the water, and an effective wattage due to cycling of 700 watts during the dry cycle.

It is normal for the heating element to cycle during Heated Dry cycle. The control energizes the heating element continuously for the first 6 minutes. The control then cycles the heating element on for 60 seconds, and off for 60 seconds for the remainder of the Heated Dry cycle.

Selecting Added Heat will energize the heater for the entire time during the last prewash cycle and the final rinse cycle. Circulation time during the final rinse is increased 2.8 times the normal with this option. If selected after the wash cycle has started, the feature will not take effect until the beginning of the next fill. This option is not available for the Rinse Only cycle.

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 problem is that the dishes are not drying correctly, don’t overlook the rinse agent. A rinse agent will improve the water sheeting action and drying performance.

It is normal for the stainless steel tub and the inner door panel to retain water droplets even though the dishes are dry.
