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 sensor turns off.
A vacuum breaker installed in the inlet plumbing
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.
In 2-speed and variable-speed models, 1 dual-speed
motor drives the basket's shaft with a V-belt.
20-60 pound capacity models use 2 bearings that are
held in place by a single cast-iron trunnion that is
bolted to the frame. 80 and 125-pound capacity
models use 2 flange-type bearings that are bolted to
the frame.
Drain
Cabinet Hardmount 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.
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.
