General

This frontload washer provides some of the same

principles of operation as the typical topload washers.

It senses water level, it dispenses the desired laundry

detergent, agitates the clothes for good cleaning action,

pumps the water out of the washer and spins the

clothing in preparation for the dryer.

The difference in operation is primarily the rotational

washing agitation created for the horizontal basket and

drum. This agitation tumbles the clothes in a clockwise,

pause, and counter-clockwise direction. This reversing

tumbling action provides an efficient washing process

and requires less water.

The cycle begins by pressing the start button, which

locks the loading door after the vend is satisfied. The

type of cycle and water temperature are determined by

the temperature selector switch and the cycle select

switch.

The inner basket starts agitating during the wash water

fill. A column of air is trapped in a pressure bulb and

hose. The air pressure continues to increase as the inner

basket fills with water until it is great enough to

activate the pressure switch which then causes the wash

fill to stop.

The regular and perm press agitate cycle tumble the

clothing in a clockwise direction for a period of 15

seconds, pauses for nine seconds and then tumbles the

clothing in a counterclockwise direction for 15

seconds. This agitation continues until the wash cycle.

The machine stops agitating and turns on the pump

which removes the wash water.

Upon completion of the wash cycle, the machine goes

into two rinse cycles. Fresh cold water is brought into

the inner basket via the mixing valve until the pressure

switch shuts off the water while agitating. The rinse

cycle consists of agitation for a predetermined amount

of time, then a spin mode with the pump running while

the machine goes into a series of 4 short 500 RPM

spins.

After all the rinse cycles have been completed, the

washer goes into a final high spin cycle to extract as

much water as possible from the clothing to prepare

them for the dryer. The spin speeds and duration of

this final high spin cycle are determined by the type of

wash cycle selected (refer to Table 1 or Table 2).

NOTE: Washer may not reach 1000 RPM because

of an out-of-balance condition. Control may limit

speed to 850, 650 or 500 RPM depending on severity

of out-of-balance condition.

Technical

The basic operational system of this washer consists of

the control, temperature switch, inverter control,

pressure switch, water valves, electric pump, A.C.

motor and cycle select switch.

The control performs all timing functions like the timer

in a topload washer.

The inverter control uses a speed sensor on the motor

to measure the drum RPM. Before entering any spin

step, the inverter control measures the RPM of motor to

sense out-of-balance. The inverter control will try to

redistribute the clothes if an out-of-balance condition

exists; the inverter control will limit the spin speed to

several speeds depending on the severity of the out-of-

balance condition. If the out-of-balance condition is

severe enough, the inverter control will limit speed to

90 RPM and will not spin.

NOTE: An out-of-balance switch is used to detect

any out-of-balance condition during spins. If this

switch opens during a spin step, the inverter control

immediately stops and then restarts the spin.
