Theory of Operation
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.
8 802748

Introduction
This reversing tumbling action provides an efficient washing process and requires less laundry detergent and less water.
The cycle begins by locking the loading door after the vend is satisfied. The type of cycle and water temperature are determined by the appropriate pads on the electronic control.
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 agitate cycle tumbles 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 or drain valve which removes the wash water.
Upon completion of the wash cycle, the machine goes into a rinse cycle. 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 where the machine goes into a series of 4 short 500 RPM spins. Two of these rinse cycles will normally take place with a third extra rinse cycle being optional. 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 (Washer)
The basic operational system of this washer consists of the electronic control, the inverter control, pressure switch, water valves, electric pump (or drain valve) and A.C. motor.
The electronic control performs all control and timing functions like the timer in a topload washer. The electronic control sends simple speed and output commands to the inverter control via serial communication. The electronic control powers the door lock, pump (or drain valve) and the inverter control.
The inverter control powers the A.C. motor and performs all motor control functions. The inverter control also powers the water and dispenser valves and passes the pressure switch status to the electronic control. The inverter control is powered through the door switch, door lock switch and electronic control. The inverter control also alerts the electronic control to any errors in the motor.
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 the drum 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.

6. No Spin (Washer)
A no spin condition is not caused by intermittent operation of the motor or motor control (inverter assembly). DO NOT replace these components for no spin complaints if the unit passes the following procedure:
General Troubleshooting
To reduce the risk of electric shock, fire, explosion, serious injury or death:
• Disconnect all electric power to the machine and accessories before servicing.
• Close gas shut-off valve to gas dryer before servicing.
• Never start machine with any guards/panels removed.
• Whenever ground wires are removed during servicing, these ground wires must be reconnected to ensure that the machine is properly grounded.
• Washer motor not grounded! Disconnect electric power before servicing motor.

WARNING
No spin.
FLW1789S
Allow unit to go
through complete
final spin cycle.
Does unit spin at
high speed?
Motor and motor control board are operating properly. Do not replace them.
Yes
With no load, rapid advance to final spin or select spin only cycle. Close door and start washer.
BEFORE replacing the motor control board, conduct the following tests.
No
Is pressure
switch or pressure
switch wiring
inoperative?
Is load
out-of-
balance?
Unit makes three attempts to re­balance out-of­balance loads. If all attempts fail, final high speed spin is aborted. ONLY proper loading can correct problem.
Yes
Is there a slow
drain, clogged
pump or
oversudsing
condition?
Pressure switch must register an "empty" condition before unit will enter spin. Clear drain or pump.
Yes
Replace switch and/or wiring.
No
No
Does unit spin now?
No
Check for broken out-of­balance switch wires. Refer to

WARNING
7. Troubleshooting Shock Absorbers
A squeaking noise, oil seen on the base of the washer, or an out-of-balance condition may mean one or more shock absorbers need to be replaced.
To determine if there is an inoperative shock:
1. Remove front access panel.
2. Check height of rod or rod spacing above shock. If all four shocks are uniform and have about two inches of rod showing when basket is empty, shocks don’t need replacing. Refer to Figure 12. If one or more shocks is showing less than two inches of rod, then an internal spring has broken and all four shocks should be replaced.
3. Check base of washer below shock absorbers for grease or oil. Shocks are not oil filled. Any oil is from grease used internally to lubricate damper of shock. A small amount of grease/oil on base is normal and doesn’t indicate failure. A large amount of grease/oil indicates a shock that might fail soon. Do not replace shock until the internal spring has broken as described in Step 2.
