COMMON CYCLE TIME CHART NOTES

NOTE 1 – CYCLE MODIFICATIONS BASED ON SENSOR INPUTS

The control monitors food soil and temperature sensors during the first four intervals of the cycle

(intervals 45-42) to determine what sensor based cycle modifications are appropriate. The modifica-

tions made to the cycle depend on the cycle and options selected as well as the sensor inputs. Note

the interval skip arrows and thermal hold temperature changes on the time chart for each version of the

cycle.

In addition to being able to modify the cycle itself based on soil sensor input, the APF (

Automatic Purge

Filtration) wash system allows the control to continuously filter and flush food soil out of the pump

during “APF enabled” intervals scattered throughout each cycle and do it without interrupting the cycle

(see note 2 on APF).

) Anti-Bacterial/Cookware, Pots&Pans/Heavy, Normal, and China Cycles

The control assumes that the worst case cycle (the heavy soil version) is going to be required

until the true soil level is determined. The soil level is determined by counting the number of

pressure switch (soil sensor) trips that occur in the first APF interval of the cycle (

interval 42).

If no trips are detected in interval 42, the control modifies the remainder of the cycle to match

the light soil/non-sensor version of the cycle. If one or more trips are detected in interval 42,

the control continues with the heavy soil version of the cycle.

Note: Energy Star models have a different light soil/non-sensor version of the Normal cycle than other

models (see Model Specifics table to identify Energy Star models).

Note: Models without pressure switches (soil sensors) never get sensor trips and thus always default

to the light/non-sensor version of the cycle and never execute APF purges. (See Model Specifics Table

to identify models without pressure switches).

Note: The Power Scour/High Temp Scrub option can override or alter the soil-based cycle modifica-

tions (see Note 14, page 34).

(b) Time Saver/Quick CleanUp Cycles

The control does NOT modify the Quick Clean Up/Time Saver cycle based on soil level. In-

stead, it modifies the cycle based on incoming water temperature detected during the first fill

interval of the cycle (interval 45). The control assumes the worst case cycle (Cool First Fill

version) will be required until the end of interval 42. At the end of interval 42, it modifies the

remainder of the cycle based on the inlet water temperature it actually detected in the first fill.

If the water was more than135°F/57°C it changes to the “Hot First Fill” version of the cycle. If

the water was less than 135°F, it will continue with the “Cool First Fill” version of the cycle. The

“Cool First Fill” version of the cycle basically contains an extra drain and fill prior to the main

wash to increase the initial water temperature for the main wash and reduce the time needed

to heat the water.

Like other cycles, the Quick CleanUp/Time Saver cycle does allow APF purges to occur (in

APF intervals) if pressure switch trips occur but the Quick CleanUp/Time Saver cycle timing

itself is not modified based on pressure switch trips or soil level.

The control does NOT modify the Rinse Only/Quick Rinse cycle based on sensor inputs. Like

other cycles, it does allow APF purges to occur (in APF intervals) if pressure switch trips occur

but the Rinse Only/Quick Rinse cycle timing itself is not modified based on any sensor inputs.
