Dishwasher Temperature Sensor
The temperature sensor system senses the water temperature in your dishwasher. This allows you to turn your central water heater down and reduce your energy cost.Hot water is essential to high-performance dishwashing. Hot water melts fatty grease and releases the detergent's strong chemical action to soften and break down food soils.
Some of our dishwashers have a temperature sensor that checks the water temperature during the main wash periods (potscrubber, normal wash or light wash). If the inlet water temperature is 140 degrees Fahrenheit or higher, the wash water will be hot enough to clean the load and no additional heat will be added. However, if the inlet water temperature is below 140 degrees Fahrenheit, the temperature sensor thermostat will extend the wash cycle and raise wash water temperature to 132 degrees Fahrenheit or higher.
The calrod heater will continue to increase water temperature until the temperature sensor is satisfied or the maximum extension time is reached (15 to 20 minutes, depending on dishwasher model). The normal cycle time sequence will then continue. This cycle extension and temperature increase combination will have the same effect as 140 degree Fahrenheit water temperature, measured at the faucet.
Wash water in temperature sensor dishwashers will generally be hotter than in dishwashers requiring 140 degree Fahrenheit inlet water and will yield improved wash performance.
