mounted in the sump.
Heater element switching is performed by the electronic via a relay. The relay (when
energized) closes contacts to provide the heater element with 120VAC. A
temperature limiter mounted with the element provides protection by opening up the
circuit should the temperature become too high.

Flow-Through Heater

The flow-through heater assembly is mounted on the (left side) exterior of the wash
cabinet. The flow-through heater is plumbed into the water path between the
circulation pump output and the middle spray arm.
The flow-through heater consists of a heater element mounted parallel to a metal
tube that water passes through when the dishwasher is circulating.
As water flows through the metal tube, the water is heated and exits through the
middle spray arm. As the water falls to the bottom of the wash cavity, it passes
through the filter and re-enters the circulation pump; the process then repeats. The
temperature sensor monitors the water temperature until the program's specified
temperature is reached. Generally, the water heats at a rate of about 20 degrees per
minute.
Heater element switching is performed by the electronic via a relay. The relay (when
energized) closes contacts to provide the heater element with 120VAC. Two
temperature limiters are mounted along the element and provide protection by
opening up the circuit should the temperature become too high.
