Thermostats and Temperature Indicators
A. Ssm-Wash or High Temperature Wash/Rinse Thermostat
Most dishwashers are equipped with a thermostat to provide for guaranteed hoi water in the 2nd Wash and/or Final
Rinse when a Sani-Wash or high temperature wash is selected. Unless the water temperature is high enough to satisfy
the thermostat, the thermostat slops the tinier until the healer in the machine raises the water temperature enough
to satisfy the thermostat.
If the water temperature in the tub is below the thermostat setting the switch remains open and the timer motor
does not run, prolonging the rinse cycle until the water temperature rises to the thermostat setting. When this
temperature is reached, the bimetal strip within the thermostat deflects and doses the contacts (closing the circuit
to the timer motor) and the timer resumes operation to complete the dishwashing cycle' See Figure 58

The heater in the machine will raise the water temperature approximately one degree per minute. Thus, if the water
is 135 degrees at the start of the Second Wash or Fourth Rinse and the thermostat is calibrated to 150 degrees,
the timer will slop for approximately 15 minutes in the Second Wash or Fourth Rinse (or both) while the water is
being healed. During the time that the thermostat is calling ior'heat, there is no power to the timer motor although
the wash system continues to function
Depending on the model dishwasher, the thermostat may be calibrated at 140° to 150“ Some Lady Kenmore
models contained 2 thermostats; one which is a round disk type, and the other which Is of
3 tubular design. The
disk type is calibrated for 150°, and the tubular type is calibrated for 120“
B. Checking Thermostat Operation
If the second wash or final rinse cycle is not delayed (when a Sani-Cyde has been selected), despite a temperature
of less than 130° F in the tub:
1. Check for incorrect wiring (use schematic).
2. Check for a defective thermostat Contacts should be open when told,
3. Check for short in thermostat circuit,
4 - Check for too low a calibration of the thermostat, Thermostat calibration may be determined by measuring the
temperature of the water expelled from the machine following a thermostatic delay
