15. Heating Element and Safety Thermostat
The heating element is located at the bottom of the sump. When the unit is energized during the heated wash cycle ,
it heats the water. The warmed air rises through the sump cover into the tub providing efficient washing and drying
of the dishes.
An inner resistance coil of nichrome wire, which does the actual heating, is completely surrounded by an electrical
insulation material. This assembly is protected by a metal sheath to help reduce damage and oxidation. Since you
can’t see the internal coil, in most cases you will have to rely on the ohm meter to determine the condition of the coil.
The safety thermostat acts as a temperature limit switch. If a malfunction causes the temperature rises above the
Limit of the thermostat, the heating element is disabled preventing damage to the dishwasher.
