General (Dryer)

The dryer uses heated air to dry loads of laundry.

When the motor is started, the exhaust fan pulls fresh

air in through louvers at the rear of the dryer and over

the heat source (burner flame for gas and heating

element for electric). The heated air moves through the

heater duct and into the cylinder, where it circulates

through the wet load. The air then passes through the

lint filter, air duct and exhaust fan, where it is vented to

the outdoors.

General (Washer)

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, removes 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 laundry detergent

and less water.

The cycle begins by pressing the start button, which

locks the loading door. The type of cycle and water

temperature are determined by the cycle select switch

and temperature selector 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 cycles 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 toTable 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 (Washer)

The basic operational system of this washer consists of

the control, temperature switch, the 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 additional 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.
