Hello
Do you have any of the extra functions selected, such as "Hi Temp Rinse" etc?
The selector switch has a selection for Hi-Temp Wash; the switch is in
parallel with a thermostat mounted on the bottom of the tub and with a
contact in the timer. The
selector switch, temp assure thermostat, and the temp boost thermostat
are all in series with the timer motor. Both thermostats are normally
open thermostats. When
the timer reaches the end of the second wash cycle, the contact in the
timer supplying power to run the timer motor will open. At which time,
if the selector switch for the Hi-Temp Wash has been selected, power to
run the timer motor must come through the thermostats. The temperature
of the water in the tub must rise to 137° ±5° F for the thermostat to
close and the timer motor to advance. If the water temperature is below
137° ± 5° F, the timer will pause until the heating element raises the
temperature of the water in the tub and allow the thermostat to close.
Hi-Temp Rinse
If the selector switch was a selection for a Hi-Temp rinse, the switch
is in parallel with a thermostat mounted in the tub, and the contact in
the timer, the same as the Hi-Temp wash. The operation for the Hi-Temp
rinse will be the same as for the Hi-Temp wash with the exception, on
some models, the temperature of the water in the tub will be 150° ± 5°
F for the thermostat to close to give a sanitizing rinse.
What do we learn from this? That you either have a bad heater or a bad
thermostat. Check the heater for continuity with our OHM meter.
