Operation and Cycle Information
This section of the guide provides details on segments of cycles, timing of cycles, temperature
expectations, and cycling of the heater during the dry portion of a cycle.
Auto Hot Start
At the beginning of the main wash, the dishwasher checks the temperature of the water, and if it is
below 90°F, then it will add up to 10 minutes of time to heat the water to 90°F by circulating the water
while the heater is on. Similarly, at the beginning of nal rinse, the dishwasher will check the water
temperature, and if it is below 105°F, then it will add up to 15 minutes of time to heat the water to 105.
Once it reaches the target temperature, any remaining hot start time will be truncated and will continue
on with the cycle.
The cycle chart below explains the segments of a cycle (cycles for all models included, not all
models contain the same cycles). It details ll and drain times which depend on either a full or partial
drain. It provides the circulation time in each segment, but does not include turbidity or temperature
adjustments or dry cycles (see the Dry System section in this guide). Times will vary depending on
turbidity response and incoming water temperature.
