Section 3
UW Theory of Operation
Starting the Machine
The door lock will not allow a cycle to be started until
the door has been closed.
Fill
The operator selects a cycle and starts the machine.
Water enters the machine through water valves that are
controlled by the microcomputer. As water fills the
basket, a column of air is trapped in a pressure bulb
and hose. The air pressure continues to increase as the
basket fills with water. When the desired water level is
reached, the water level switch triggers the
microcomputer and the water valves turn off.
A vacuum breaker installed in the inlet plumbing or a
shell overflow and air gap prevents the backflow of
water.
Supply
The operator can either connect external liquid
supplies to the machine or fill the supply dispenser
with liquid or dry supplies. The supply dispenser’s
nozzles flush the compartments with water at the
appropriate times throughout a cycle.
Wash
The basket includes ribs that lift the laundry from the
wash water. The laundry then tumbles back into the
bath.
1 dual-speed motor drives the basket’s shaft with a V-
belt.
UW35, UW60, UW80, UW100 and UW125 models
use 2 flange-type bearing that are bolted to the frame.
UW150 models use 2 bearings that are held in place
by a single cast-iron trunnion that is bolted to the
frame.
Spray-Rinse
The spray-rinse consists of a hose connected from the
hot and cold water inlet spray valves to the center of
the door glass. A nozzle on the inside of the door glass
produces a fan-shaped spray that disperses water
throughout the load.
Drain
UW washer-extractors use a normally-open gravity-
type drain system. No pump is used. When the drain
valve opens, the perforated basket allows water to
drain from it.
In the event of a power failure, the drain valve will
open automatically and the machine will drain.
UW 35 and 60 washer-extractors include a single drain
valve. UW 80, 100, 125 and 150 models include 2
drain valves. On dual drain models, the 2 drain valves
open and close together.
Extract
A final high-speed extract step removes water from the
load, which maximizes drying efficiency.
The door lock system will not allow the door to be
opened until the cycle has finished.

Section 4
Troubleshooting
To reduce the risk of electrical shock, fire, explosion, serious injury or death:
· Disconnect electrical power to the washer-extractor before servicing it.
· Close the gas shut-off valve to the washer-extractor (when applicable) before servicing it.
· Never start the washer-extractor with any guards/panels removed.
· Whenever ground wires are removed during servicing, these ground wires must be
reconnected to ensure that the washer-extractor is properly grounded.
