Kenmore 808353 - Manual (Page 56)

Since the thermostats are subjected to varying conditions within the home, it is extremely irnporiam that they be
secured firmiy against the door or tub of the dishwasher in order to accurately sense the internal temperature
The DufDose ot the liahts is to indicate to the user of the dishwasher whether the hot water supplied to the machine
is hot enough to produce good dishwashing results. The "Coo)” light will remain on until the water temperature m
the dishwasher reaches 140® at which time the light switches from "Cool" to "Normal
Dishwashing detergents state that temperatures delivered to the inlet valve must be at least 140 degrees. This ^
minimum temperature is required because of the severe drop in water temperature as water enters a_cola sieenuD
and the fact that it must "heat up" the tub interior and its contents before it can be expected to maintain the inlet
water temperature
For example; if water at the tap measures 140 degrees upon entrance into a cold dishwasher, this water temperature
will drop to approximately 115 degrees or less depending on the size of the load and №e kind of dishware in the load
See Figure 62 As you can readily see. this would give only minimal warm water in the first wash to activate the
detergent The hotter the water is on the first fill, the quicker you will heat the tub and contents, and the belter
you wilt maintain the heat
Long water runs, hot water pipes that pass through concrete slabs and crawl spaces will tend to cool the water
between fills Urrdercounter units that have an outside wall across the side or back lend to keep the tub cool
Therefore, always make yourself aware of all the conditions that can affect water temperature in your home.
Also remember that any test involving thermostats and sensing devices must be done with all panel and components
in place throughout the testing
Water
Hegl
Option 130°/
140°
Some models produced beginning in 1982 have a water heat option controlled by a 130 /140 tubular type thermo­
stat These models delay in the 2nd rinse, 2 nd wash, and final rinse H the thermostat is not satisfied
Hot Rinse Option 150^
Some models have a hoi rinse option in the final rinse This functions exactly like the sani-lemp option of 150° in the
final rinse The hot rinse option is controlled through a 150° tubular thermostat
High Limit Thermostat 180°
Models produced after 1982 have a 180° high limit thermostat This is a tubular type; it is normally closed It breaks
the circuit to the heater when the temperature rating is reached On some models this thermostat may be replaced
by a thermal fuse rated at 100°C This is located in the thermostat bracket on the door liner
