Option selections allow the user flexibility to alter a
wash cycle to their desires. These options are the
speed of the wash motor this will increase water
pressure sprayed on the load, the temperature of
water in both the main wash and finial rinse seg-
ment of a cycle, the dry can be a no heat dry or on
some models the heated dry can actually be
extended for a longer time. This section cover
these and a delay start option.

Wash Pressure

This option allows the user to raise or lower the
speed of the wash motor which increases or de-
creases the pressure of the water used to clean the
dishes. The control will not allow this change in all
cycles because of the intent of the cycle. This
change in water pressure will effect all of the washes
and rinses in this selected cycle.
Depending on model, the option could read either
"High" or "Maxx" speed. This selection will
substitute the speed of the motor to 3400 rpm when
spraying from the lower spray arm and 3200 rpm
from the upper and center arms. This overrides the
variable speed function of the selected cycle.
Delicate Pressure limits all wash and rinse speeds
to 2800 rpm only for the selected cycle.

Wash Temperature

This option allows for the selection of a high tem-
perature wash in select cycles. The high tempera-
ture wash occurs at the end of the main wash
segment of the cycle.
The display will flash an HO on models so equipped.
This option will increase the water temperature to
140°. There is a time override for this option of not
more then 10 minute.

Sanitize Rinse

The Sanitize rinse increases the finial rinse segment
to a temperature of 155° on select wash cycles. On
models PLD4555RFC and LRDB500FEE when the
sanitize rinse option is selected this selects the High
Temp wash as well, for that reason, both the Sanitize
and Hi temp wash indicators will light. On other
models, this is a separate option. There can be up to
30 minutes delay for the Sanitize rinse when se-
lected. On models with a display, an HO will flash
during this delay period. Once the wash cycle is
completed, the Sanitize light and the Clean light are
light and remain on until the door is opened. If the
155° was not reached in the allotted time, the
Sanitize light will not come on informing the user the
criteria for this setting was not met.

Dry

This option, on all models, can disable the heating
element which gives only an air dry. There is an
active vent and fan assembly located in the top right
back corner of the tub that will be activated at the
end of all wash cycles. On select models, the Dry
option also offers a Max or a Sahara dry, this setting
lengths the dry cycle by 20 minutes to insure a dry
load. If when the dishwasher is in the dry cycle the
door is opened and stays open for more then one
minute the remainder of the dry cycle will cancel out.

Delay Start

T
his option allows for a wash cycle to be pro-
grammed into the control and the start delayed for a
set number of hours. A cycle can be delayed from 1
to 24 hours in 1 hour increments. To set a Delay
Start a wash cycle with options is selected followed
by pressing the Delay Start pad. Each time the Delay
Start pad is pressed in 3 second intervals the number
of hours to delay will increase by one hour up to 24
hours. Once the delay begins, time is decreased in
one hour segments until one hour remains, then the
count down changes to minutes. After the count
down starts pressing the Start/Cancel pad will have
no effect on the delay start, if the Start/Cancel pad is
a second time in succession this will cancel the delay
and start the selected cycle.
