Section 2 Introduction

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, tumbles the clothes for good cleaning action, pumps the water out of the washer and spins the clothing for preparing for the dryer.

The difference in operation is primarily the rotational washing cycle that tumbles the clothes in a timer controlled clockwise, pause and then a counterclockwise direction. This reversing cycled tumbling action provides a much more efficient washing process which requires less laundry detergent and less water.

The cycle begins by locking the loading door with a wash fill command from the timer. The water temperature is determined by the temperature selector.

While water fills the inner basket, 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. The pressure switch then causes the wash fill to stop and starts the reversing rotational washing cycle.

The reversing rotational cycle tumbles the clothing in a clockwise direction for a period of 20 seconds, pauses for 9 seconds and then tumbles the clothing in a counterclockwise direction for ten seconds. This action continues until the completion of the wash cycle selected on the timer.

Upon completion of the wash cycle, the machine goes into a rinse cycle. The rinse cycle consists of a spin mode that removes the majority of the detergent water from the clothing and also activates the electric water pump which removes the wash water. Fresh temperature selected water is brought into the inner basket via the mixing valve, the pressure switch shuts off the water and then a rinse cycle starts. The rinse cycle consists of a tumble reversing action similar to the washing cycle for a pre-determined amount of time, a spin mode, and includes water being pumped out and fresh water being brought into the washer. Several of these rinse cycles will take place, based upon the operator timer wash type selection.

After all the rinse cycles have been completed, the washer goes into a 1059 rpm final spin cycle for 90 seconds to extract as much water as possible from the clothing, preparing them for the dryer. When this fast spin cycle is completed, the washer goes into a fluff tumble mode similar to agitate, only without water. Operation stops and the loading door interlock is deactivated allowing operator entry into the washer.

Technical

The basic operational controls of this washer consists of the motor control logic board, timer, pressure switch, temperature switch, D.C. motor and electric pump.

The principle of operation remains the same as other washing machines. The door locks and starts the timer. The timer starts the machine process by first having the electronic control activate the dual water inlet mixing valve which starts to fill the washer via the dispenser mixing valve. The water temperature is determined by the operator selected temperature switch position, which selects the hot, cold or both mixing valves. The second step is adding the detergent and other washing ingredients. This process continues until the air pressure, via the pressure bulb and hose, activates the pressure switch, which overrides the timer fill command.

The timer continues its rotational cycle, which then sends the command to the motor control board to start the timer rotator. The tumble rotating action is a specific wash cycle rotation, pause and then reverse rotation. This process continues for an operator’s selected period of time.

The next command mode the timer signals to the motor control board is to start the rinse cycle. This cycle signals the electric pump to turn on and direct the wash water out of the washer. The motor control board then commands the motor to go into a faster spin cycle in an attempt to remove a reasonable amount of water out of the clothing. The spin cycle stops and then adds fresh rinse water into the washer via the inlet mixing valve and dispenser hose. After the pressure switch shuts off the water inlet mixing valve, the motor control board commands the motor to start the normal wash rotational, pause, reverse direction process for a timer controlled amount of time. This rinse cycle is completed twice.

The next portion of the wash cycle is the spin cycle. In this cycle the control board turns the electric pump on to remove the rinse water from the tub. The washer will spin at a distribution speed of 90 rpm until the pressure switch is satisfied as empty. The washer then goes to a 500 rpm spin for 30 seconds and returns to the 90 rpm distribution speed for another 30 seconds. This allows the motor control board to “sense” the outof-balance condition of the load. This sequence is repeated any time the washer attempts to go to a spin speed. At this time the washer then goes into a final spin mode of 650 rpm for approximately 5 minutes and ramps up to 1059* rpm for the remaining 90 seconds.

*(For Regular and Rinse and Spin cycles only).

Washer Troubleshooting

WARNING

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.

1. NO SPIN CONDITION – MODELS THROUGH SERIAL NO. 9811005968 A “no spin” condition could be the result of an open circuit in the wire harness or out-of-balance switch.

a. Check that the harness is still connected to the out-of-balance switch. The wiring diagram may show the out-

of-balance switch as a normally open switch which is incorrect. The switch is a normally closed switch. b. To test the electrical circuit, disconnect electrical power to the washer. c. Remove the “H3” connector from the motor control board. d. Use an Ohm meter and check the black/white to violet/white wires. Circuit should read closed, an open

reading indicates a bad switch or wire harness problem. e. Flex the harness at the plastic retainer and test the switch and if okay, the base wire harness has an open

circuit and MUST be replaced.

f. After replacing the wire harness, tape the harness wires to the left front shock 1 ½ inches from top of shock.

Refer to Figure 1.

W003

IMPORTANT: Leave a minimum of 8 inches of slack between tape on shock and the plastic wire retainer on the out-of-balance switch mounting bracket. Refer to Figure 1.

2. TROUBLESHOOTING KNOCKING NOISE

If a frontload washer produces a noise similar to a knock on a door, it might be due to a flat spot on the belt. The knocking sound is made when the flat spot hits the pulley. The knocking may occur during a pulse spin and fade after reaching a higher RPM.

To correct this condition, replace the washer belt.

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.

3. NO MOTOR ROTATION, OR DRIVE FAILURE CODE “E:DF” ON ELECTRONIC DISPLAY UNITS

NOTE: Verify that motor is receiving proper voltage. Disconnect electrical power to washer.

TEST PROCEDURE

a. At the rear of the washer, remove the lower access panel. b. Reach in through the access panel opening and disconnect motor wire harness from motor. c. Using an Ohmmeter, measure resistance at the terminals on the motor. Refer to Tab le 1.

Motor Resistance Values

TACH INPUT Terminals 6-7 Approximately 15 Ohms

W003

BRUSHES Terminals 4-5 Less than 70 Ohms

WINDING Terminals 1-3 Approximately 1.1 Ohms

WINDING Terminals 1-2 Approximately 2.0-2.4 Ohms

WINDING Terminals 2-3 Approximately 3.4 Ohms

NOTE: Resistance values may vary depending on type of Ohmmeter used.

Tab le 1

d. Replace motor if there is an open circuit on tach input (terminals 6-7) or winding circuits (terminals 1, 2 and

3), or if there is continuity between any terminal and the motor housing.

e. An open circuit between terminals 4 and 5 indicates a stuck or worn brush. Refer to appropriate service

procedure below.

SERVICE PROCEDURE: STUCK BRUSHES

a. Remove motor from washer. b. Using a flashlight, view brushes through holes in motor end shield. Refer to Figure 2. c. Inspect both brushes to determine if either brush braided wire is binding the brush movement. The braided

wire might be snagged on the seam in the corner of the metal brush holder. Refer to Figure 2.

NOTE: The copper braided wire should be located in the center of the brush assembly. If the braided wire has fallen to the bottom of the brush, it will cause binding.

d. After determining which brush assembly is binding, carefully use the tip of a small screwdriver to unsnag

and reposition the braided wire. Refer to Figure 3. Make sure spring is making unobstructed contact with the end of the brush. Rotate armature by hand to assure that brushes are seated.

e. Recheck resistance between motor terminals 4 and 5 to verify the brush position has been corrected.

f. Reinstall motor in washer.

g. Run washer through cycle to verify proper operation.
