Operation
Cycle Execution (continued)
Each of the 30 cycles consists of 8 segments. A
typical cycle has Prewash, Wash, and Rinses
(up to six are available). Upon the completion
of the last rinse, a final spin occurs. Following
is a description of each cycle segment.
Fill
After the start key is pressed, the drain is closed
and the machine begins filling to the
appropriate water level. Each wash segment
begins with a fill. After the water level is
reached, the cycle time begins to count down
(the cycle timer is paused during fill, heat and
drain steps). If a supply is programmed during
the segment, the dispenser will be flushed
during the fill.
If the machine is connected to an external
chemical supply system, the programmed
supply will begin 10 seconds into the fill. The
supply remains on until the programmed water
level is reached, or sixty seconds have elapsed.
If the water level is not reached after 30
minutes, the display will flash Stop and Fill.
The onboard beeper will also sound for 10
seconds. The machine will then enter the stop
routine.
Wash
Standard Wash
As soon as the programmed water level is
reached (and any programmed temperature is
reached) the display begins to count down the
remaining time left in the cycle.
All except three cycles use the standard
agitation profile. This agitation profile is active
during prewash, wash, and rinses. The
standard sequence is:
> 12 seconds counterclockwise at wash
speed
> 3 second pause
> 12 seconds clockwise at wash speed
> 3 second pause
Gentle Wash
Cycles 8, 16, and 24 use a gentle agitation
profile. This profile is used in the prewash,
wash, and rinse steps. The gentle wash
agitation profile is:
> 3 seconds counterclockwise at wash
speed
> 12 second pause
> 3 seconds clockwise at wash speed
> 12 second pause
Heat
If a wash segment contains a heat step, the
heating elements will begin to heat the wash
solution after the programmed level has been
reached. If the water does not reach the
desired temperature after 30 minutes, the
machine will progress to the next step.
Drain
At the conclusion of a prewash, wash, or rinse
segment, the drain valve opens and the wash
cylinder turns clockwise at wash speed. The
machine should drain in less than 30 seconds.
If draining takes longer than this, a clogged
drain hose is usually to blame. Contact a
qualified service technician.
After the water level has fallen below the low
level, there is a fifteen second delay, during
which the computer monitors the water level. If
water is sensed, the computer waits until both
high and low level inputs show that there is no
water in the wash cylinder. Assuming no water
is detected, the drain sequence concludes, and
the computer proceeds to the next segment.
Spin
After the drain sequence, the machine
progresses to spin speed if the spin time is not
zero. The displayed time will continue counting
down. After the programmed spin time has
elapsed, the next segment of the wash cycle
begins or the stop routine begins, if the spin
was the final spin of the wash cycle.
