How Your Washer Works

TLW306S

201520R6

Introduction

The cycle begins with a wash fill. The water temperature is determined by the temperature selector. While water fills the washtub, a column of air is trapped in a pressure bulb and hose. The air pressure continues to increase as the washtub fills with water until it is great enough to activate the pressure switch. The pressure switch then causes the wash fill to stop and wash agitation to begin. However, the loading door must be closed for the washer to agitate or spin.

The washer uses a reversing type motor, a special drive belt and an idler assembly. The idler assembly applies tension to the outside of the drive belt.

During agitation, the motor runs in the counterclockwise direction. The spring tension on the idler pulley applies the tension required to reduce the slack on the drive belt and maintain maximum belt to motor pulley contact. This eliminates belt slippage and ensures an efficient wash action, even with extra large loads.

The belt drives the transmission drive pulley in the counterclockwise direction. The pulley drives the helix which is splined to the input shaft of the transmission. This causes the input shaft to turn inside of a roller clutch which is pressed into the transmission cover. This roller clutch acts as a bearing in the counterclockwise direction allowing the transmission gears to operate. The transmission’s rack and pinion gear design produces a 210 degree agitation st roke at the output shaft of the transmission which drives the agitator. The brake assembly remains locked during the agitation mode since no pressure is applied to it by the transmission drive pulley.

As water is removed by the pump and the momentum of the washtub increases, the idler spring tension gradually overcomes the belt tension removing the belt slack. This eventually increases the belt to pulley contact until maximum spin speed is achieved.

The drive pulley turns clockwise riding up the ramps of the helix, exerting pressure on the brake and forcing it to release from brake pads. The helix drives the input shaft of the transmission, and when the input shaft turns in the clockwise direction the roller clutch locks onto the shaft causing the entire transmission assembly to turn. None of the gears in the transmission are operating at this time. The hub of the washtub is splined to the transmission tube and rotates with the transmission assembly. The centrifugal force created by the spinning washtub causes water to be extracted from the clothes.

Water is introduced during the first spin to “SPRAY” the garments and remove suds from them. The initial spin is followed by rinse agitation to rinse away any detergent residue. The washer fills and then agitates like the wash portion of the cycle. Following rinse agitation, a final spin extracts the rinse water from the clothes preparing them for the dryer.

After the wash agitation is completed, the timer advances into the first spin. During spin, the motor reverses turning in the clockwise direction to spin the water out of the washtub. The combination of water, washtub and load weight cause the drive belt tension on the idler side of the belt to overtake the idler spring pressure allowing the belt to become slack on the opposite side. This reduces the belt to pulley contact and allows slipping between the belt and pulley.

Section 3

To reduce the risk of electric shock, fire, explosion, serious injury or death:

• Disconnect electric power to the washer before servicing.

• Never start the washer with any guards/panels removed.

• Whenever ground wires are removed during servicing, these ground wires must be

reconnected to ensure that the washer is properly grounded.

W003

WARNING

Troubleshooting

IMPORTANT: Refer to Wiring Diagram for aid in testing washer components.

1. Low Water Level on High Fill Setting

a. If there is an instance of a low water level on the

highest fill setting, check that the high setting water level is approximately 1.5 inches below the top row of washtub holes.

b. If the water level is within .5 inch of this level

without clothes, it is performing as designed. Recent new mandates from the Department of Energy (DOE) call for certain efficiencies to be met by all washer manufacturers which require the use of a different pressure switch to meet these requirements. No modification can be made to the washer to fill higher on this setting.

2. Clicking Noise During Operation on NEWLY Installed Units

If a clicking noise is heard when first starting up a new topload washer, the noise is related to the belt taking a temporary “set” around the idler pulley . The set causes a slight bump in the belt which in turn causes the idler lever to tap the motor bracket making the clicking noise. THE BELT DOES NOT NEED TO BE REPLACED.

To correct this condition please perform the following break-in procedure:

1. After installing the unit start a fill cycle to make sure the seals have been lubricated.

2. Stop the fill cycle and place the unit into a spin cycle.

3. Run the cycle for several minutes until the belt has warmed up. This will remove the “set.”

4. Normal use will keep the belt from resetting.

5. For extended periods of non-use (three to four weeks), this procedure might need to be repeated.
