The cylinder is constructed with four lifters or
ribs that lift the laundry from the bath solution
when the cylinder rotates at slow speed and
then allow the laundry to tumble back into the
bath. This mechanical action accomplishes the
washing function. The cylinder is perforated,
allowing the water to drain from within during
the wash and extract steps.
The spray rinse feature consists of a fiber-
reinforced clear hose connected to the center
of the door glass and to both a hot and cold
water inlet valve. A hemispherically-shaped
spray nozzle inside the door glass produces a
fan-action water spray which disperses rinse
water throughout the load.
All UWPV washer-extractors use an AC
inverter drive control which provides seven
preset motor speeds using a single motor.
The AC drive interface board converts motor
logic from the WE-6 computer to the correct
signals for the AC inverter drive. In addition,
all logic inputs to the computer are routed
through this board.
The operator can select from among 39
preprogrammed cycles. Cycle 01 is a test cycle
used to verify proper operation of the washer-
extractor. With the exception of Cycle 39, the
remaining cycles are complete wash cycles or
specialty cycles designed to handle various
fabrics at specific water temperatures and
levels. Cycle 39 is designed to test an external
chemical injection supply system.
Programmable custom cycles are another
feature of the UWPV.
The vibration safety switch system utilizes a
micro-switch mounted between the faces of
the A-frame to signal the WE-6 computer that
the load imbalance is too great for high extract

speeds. Depending on the design series, the
vibration safety switch will perform in either
of two ways. If the washer-extractor utilizes
ONLY the vibration safety switch to detect an
out-of-balance load, the switch will signal the
WE-6 computer to slow the motor speed,
allowing the load to re-distribute, and then
resume the spin speed programmed. The
computer will attempt to redistribute the load
in this manner up to three times. On the third
attempt, if an imbalance condition is still
detected, the computer will abort the spin
speed step(s) and advance to the next non-spin
speed step.
However, if the washer-extractor is equipped
with BOTH the vibration safety switch and the
inverter drive balance detection systems, the
function of the switch is slightly different. The
inverter drive will monitor load imbalance
conditions and the computer will determine the
maximum safe spin speed. During the spin
cycle, if the vibration safety switch detects a
severe imbalance, due to improper installation
or improper loading of the washer, the
computer will abort the remaining portion of
the cycle and stop the machine. The display
will flash "BAL DR" while aborting the cycle
until the door has been opened.
Water enters the washer-extractor through
electromechanical water valves controlled by
the microcomputer. The microcomputer also
controls the drain and the door lock. In
addition, it selects the water levels according
to the programmed cycle. Vacuum breakers are
installed in the water-inlet plumbing to prevent
backflow of water.
