Digital Display

The digital display is to indicate the current status of
the cycle.  The display is a two digit display so time
will read from 1 to 99 minutes.  If a cycle length is
over 99 minutes, the display will have a plus sign (+)
to the right of the numbers. This plus sign (+) will
stay light until the cycle time drops below 99 min-
utes.  The display may also have codes appear to
indicate the status of the cycle or the condition of the
dishwasher.  The most common of these codes is an
HO code which may appear and flash in the display,
this indicates that the control has delayed the cycle
to increase the water temperature. Another of these
codes is a flashing CL indicates of an open door.
This code can appear if the control is programmed
and the Start/Cancel pad is pressed before the door
is closed.  Close the door and the cycle will start.
The last of the common codes is a PF code.  This
will flash in the display on initial power up of the
dishwasher or any time power to the dishwasher has
been interrupted.  There are fault codes that can
appear in the display as well; these will be listed as
failure codes in the control test section of this
manual.

Status Indicators

The 

WASHING

 indicator is energized at the begin-

ning of any wash cycle and will remain on as long as
the vent actuator is not energized.

The 

DRYING

 indicator is energized when the vent

actuator is energized and remains on until the end of
the cycle regardless of which drying option is se-
lected.

The 

CLEAN

 indicator is energized at the end of all

wash cycles with the exception of a Rinse and hold
cycle.  The clean indicator will remain on until the
door is opened.  After the door is open, ALL indicators
will be extinguished with the exception of the “Rinse
aid low” if applicable.

The 

SANITIZE 

indicator is shown in the front display

as an “S” and will be energized at the end of any
cycle that the Santi option has been selected.  The
sanitize criteria must be completed correctly for this
indicator to come on.  This indicator will be extin-
guished when the door is opened.

The 

Rinse Agent LOW

 indicator on the keypad will

be on any time the rinse aid level in the dispenser is
low.  This light will stay on until the dispenser is filled.
The indicator can also be extinguished after 5
successive cycles have been run with out filling the
dispenser.  On select models an Lo will appear in the
front display to indicate the rinse aid dispenser is low
on agent.

Wash System

The wash system consists of

 

wash pump and motor

assembly to provide water under pressure for the
three spray arms used to clean the dishes. These
three spray arms will alternate operation starting with
the lower spray arm.  After a predetermined time the
spray will change to the center and upper spray arms
simultaneously.

Control Lock

The control lock disables the keypad so that the
settings entered into the control can not be changed.
To activate the control lock press and hold the Delay
Start pad for 3 seconds with the dishwasher door
closed.  The Control Lock indicator will illuminate
when the lock is set.  To remove the control lock
press and hold the Delay Start pad for 3 seconds
until the light goes out.  If the control lock is used, it
should be turned off after the cycle is completed and
before the door is opened.

If the control lock was used and not turned off before
the dishwasher door is opened the light will go out
with the control still locked, resulting in a non func-
tioning dishwasher.  This can be corrected by
removing power from the unit this will reset the
control.

Below the lower spray arm is the filter and soil
director this covers the complete sump.  The filter is
intended to block loosened food particles from
entering the wash sump area as they fall to the
bottom from the spray action. See Figure 4
