OPERATION
MAIN WASH / TEMP ASSURE
After the final reading by the soil sensor, the unit drains before starting to fill for the
main wash. The tub fills, with the wash motor starting after the low level pressure
switch is activated. The detergent dispenser now opens,
introducing detergent into the wash cycle. The electronic
control checks the water temperature through the
thermistor, energizing the inline heater to maintain or heat
the wash water entering the second level spray arm.
The main wash temperature has been predetermined for
the wash cycle selected. At this point, depending on the
required temperature (Temp Assure), the electronic control
pauses the time remaining to allow the wash water to heat
to the desired setting. If Temp Assure is not reached, the
dishwasher pauses time between 0 and 10 minutes to allow
the temperature to increase during several periods of the
main wash. Once the main wash cycle is completed, the
dishwasher goes through the drain phase before filling for
the rinse phase of the cycle.
TEMPERATURE CONTROLS
Options allow the consumer the choice to control the temperature at which the
main wash operates. The main wash water can be heated to increase the
performance of the chosen wash cycle.
If the High Temp option is chosen, the required temperature (Temp Assure) during
the main wash is increased to 140° F. The control will pause the time remaining for
up to 10 minutes to allow the water to heat to this temperature. Whether or not the
water temperature reaches this in 10 minutes, the cycle continues without
indication that it reached or did not reach this temperature.
When the Sanitize option is chosen, the National Sanitation Foundation requires, in
the final rinse cycle, that 155° F. be reached and maintained for a certain amount of
time. During the final rinse, the control pauses the time remaining for up to 30
minutes to reach Temp Assure (155° F for Sanitize) before proceeding to the end of
the cycle. Should the cycle meet the requirements defined by the Sanitize option,
the Sanitize ring will remain lit following the completion of the cycle. The ring will not
light if Temp Assure is not met.
