b. Blockage or crimp in the drain hose. c. Drain pipe not vented.

2. Water on the floor. Causes: a. A leaking hose on the water inlet valve or faucet.

b. A leaking drain hose connection. c. The drain hose is coming out of the stand pipe when draining. d. Restricted drain pipe -- running beyond capacity.

3. The machine vibrates or “walks”. Causes: a. Improperly installed front feet.

b. The washer is not level. c. The shipping strap is not removed or a retaining pin is still attached to a

shipping pin on the base of the washer. d. Floor not solid. e. Rear leveling legs not set.

4. The machine doesn’t fill. Causes: a. The water faucets are not turned on.

b. There is a blockage in the hose or the fill valves. c. Drain hose siphoning -- too low or siphon break not installed.

Section One - Part B

THEORY OF OPERATION

All washers perform essentially the same four functions. They fill with water, agitate, drain the water and spin the water out of the clothing.

Water Fill

Valve

Fig. 2-1

1. Before the washer can fill, the customer makes selections that:

• Control the length of the wash cycle by turning the timer control knob

• Control the temperature of the wash and rinse water by setting the water temperature switch. The water temperature switch is identified by the dotted box in Fig. 2-2. The wash temp switch chart indicates three possible switches, depending on the model washer being used. The switch letters in the chart, H W and C are the possible water temperature selections, Hot , Warm and Cold. The first letter is the wash temperature, the second letter is the rinse temperature.

• Control the amount of water required for the amount of clothing by setting the water level or pressure switch.

2. Once the selections are made, a series of switches are closed in the timer and water temperature switch. If, for example, the customer selects the beginning of the REGULAR cycle, increment 4, and a WARM wash and COLD rinse, the following switches would be closed.

Fig. 2-2

Fig. 2-3

The water level switch is set to move from the EMPTY position to the FULL position depending on how much tension is set on the switch diaphragm.

3. When the customer pulls the timer knob out,

voltage is supplied to the hot and/or cold water inlet solenoids. In the example above, both solenoids are energized to allow water to fill the tub.

4. As the water level rises in the tub, it causes

an increase in air pressure in the air dome assembly mounted to the side of the tub. A hose between the air dome and the water level switch transfers this air pressure against the diaphragm in the water level switch, causing electrical contacts to move from V to P , (EMPTY position), to V to T, (FULL position). The washer stops filling and the water level switch is providing voltage to the timer motor and the drive motor to begin agitation.

1. Once there is power to the timer motor, the timer will start to advance. The drive motor will also

begin to turn counterclockwise in the agitation direction. The direction of current through the dirve motor start winding will determine the direction the drive motor runs. In the agitation mode, contacts 7 are closed, causing current to flow in the start winding opposite the flow in the run winding.

Fig. 2-9

2. The motor is coupled directly to the transmis-

sion and will cause the transmission shaft to turn in the agitate direction. The agitator is mounted directly to the transmission shaft and is driven back and forth to provide agitation.

3. The water pump is mounted directly to the

motor and will also turn in the agitate direction. At this point the pump is running in reverse, so water does not leave the tub.

4. During the agitation cycle, the wash water is

being pulled through a basket mounted lint filter, (if equpped), by pumping vanes molded into the underside of the agitator. Due to the shape of the filter, lint is captured on the filter fins.

5. Also, during the agitation cycle, the transmis-

sion is being set up for neutral drain to provide a pump-out prior to going into spin.

6. Once the timer has advanced to the end of

the wash cycle, contacts open in the timer causing the drive motor to stop.

1. The timer advances to the next step in the process, which is the drain cycle. This time, contacts 14

in the timer are closed, energizing the drive motor to run in a clockwise direction. The current flow in the start winding is the same as that in the run winding.

Fig. 2-13

2. The drive motor now turns the pump in the clockwise or drain direction causing the pump to drain

the dirty water out of the tub through the drain hose.

3. The weight of the water being pulled over the lint filter flushes the lint from the filter and out the

drain hose with the dirty water.

Fig. 2-14

4. After a two-minute drain, the timer contacts open momentarily , stopping the drive motor . This

momentary pause causes the transmission to reset itself for the spin cycle.

1. After the motor restarts, in the same clockwise direction, the transmission is reset for the spin

mode and the spin pinion begins to turn.

2. A clutch housing is mounted directly to the transmission spin pinion and begins to turn as well.

3. Inside the clutch housing is a clutch lining that is turned by the clutch housing by friction. The clutch

lining is an almost complete circular band that is cushioned with a spring to allow the clutch to slip as the basket is coming up to speed. This slip prevents high torque loads on the motor and allows the motor to bring this heavy load up to speed without overloading.

4. The clutch lining is designed to contact the basket drive brake cam which releases the basket

drive brakes during the spin cycle, allowing the basket drive to turn freely .

5. The basket drive is connected to the basket with a drive block and nut. The turning basket drive

causes the basket to begin to spin.

6. As the basket gets up to its full spin speed, the clutch slippage is gradually reduced until the clutch,

basket drive and basket are being driven as if they were one unit.
