The Design and Operation of the
Fully Intergraded Dishwasher.
The fully integrated control places all cycle selection
and options on top of the console out of sight with
the door closed. With the controls under the counter
top while in operation, the cycle selection needs to
be accomplished with the door opened. First select
a wash cycle and any options, then press the Start/
Cancel pad or a Delayed Start pad and close the
door the cycle begins. A display mounted in the front
of the console shows the time remaining of the delay
or the time remaining in the cycle. While in operation,
the dishwasher control monitors the progress of the
cycle to determined if changes need to be made to
improve the cycle performance. Changes to the
cycle can start as early as the first fill, if food soils in
the water deems it necessary. If the user wishes to
make a change to the cycle, it needs to be done
before the completion of the first fill. After that time
any changes to a wash cycle will require a Cancel/
Drain before a new wash cycle can be selected.
While in operation, the control monitors all aspects of
the cycle with the use of sensors mounted in the
sump. These sensors enable the control to adjust
the length of the cycle based on soil level and water
temperature and are made as needed.
As stated earlier, a wash cycle can not be changed
after the first fill without a Cancel/Drain, options to
the wash cycle can be changed at any time up to
the point they are to be applied. If at any time after
the cycle has been started, the door is opened the
unit will stop, by closing the door the operations will
resume without pressing the Start/Cancel pad. If a
cycle needs to be terminated after the first fill has
started touching the Start/Cancel pad once sends
the unit into a Cancel/Drain for 90 seconds, this
terminates this selection. If while in a Cancel/Drain
the Start/Cancel pad is pressed a second time the
drain action stops immediately. At the completion of
a wash cycle the control lights the Clean indicator;
this indicator remains on until the door is opened.
After the wash cycle is completed and the door
opened when the Start/Cancel pad is pressed for a
new load the control will repeat the previous run
cycle, including all of the previously selected
options.
Added to the fully integrated control, the new design
offers, a new control console which is decreased in
height. The vent and door latch release handle that
had added to the height have been redesigned. The
towel bar handle once decoration now becomes the
door opening handle.
