Knowledge of the dishwasher’s cycles and systems is necessary in diagnosing any potential 
operational problems. Methods for diagnosing these problems, such as taking resistance 
readings and testing for closed circuits are outlined in the following section as well.

Dishwasher Control

All of the functions and operations of this dishwasher are dictated and monitored by the electronic 

control. The control maintains the proper water temperature in the wash and rinse cycles to ensure 

proper cleaning for the wash cycle selected. (This temperature may not be the same for all cycles.)  

The control also monitors the soil concentration in the water with the use of a turbidity sensor mounted 

in the sump.

Auto Wash

This cycle factors in the size of the load, the amount of soil on the dishes, and the temperature of the 

water to create an appropriate cycle for each load. Auto wash uses water temperature to determine 

the length of the wash cycle. Water temperature is monitored to assess the rate at which the water 

temperature decreases. A rapid decrease in temperature alerts the control to extend the wash time. 

(Larger loads have higher rates of temperature decrease, therefore longer wash cycles.) 
As the water is assessed for temperature changes, it is also adjusted to maintain proper temperature 

throughout the cycle. The control also checks the soil concentration in the water to determine the 

number of rinses needed for cleaning. 

Heavy Wash

This cycle is intended for heavy soil levels. The water temperatures for both wash and rinse cycles are 

automatically selected. It includes a high temperature wash and sanitize rinse. Soil sensing is used in 

this cycle.

Normal Wash 

This cycle is intended for normal soil level. All options (high temperature wash, sanitize rinse, and delay 

start) are available at the user’s discretion. Soil sensing is used in this cycle.

Short Wash

This cycle is intended for light soil levels. All options (high temperature wash, sanitize rinse, and delay 

start) are available at the user’s discretion. Soil sensing is used in this cycle.

Rinse Hold

This cycle is intended for dishes that are to be washed later. It is a rinse-only cycle; options and soil 

sensing are not available.

Component Function Test

Water/Service Test

The service test will check the electronic control’s ability to run all functions of the dishwasher.  

This test may be entered from an idle mode or the power failure mode, however different pads  

are used to activate.
