Rinse

Cycles

The control can add an additional 5 rinse cycles.

Customer makes normal selections and presses the START pad. Any time after that if the customer presses the “OPTIONS” pad the display will show a 1. Pressing the “OPTIONS” pad again will change to 2. The customer can scroll up

to 5 rinse cycles

. Once the customer stops scrolling, the display will automatically add additional cycles and time to the Est Minutes Remaining. (Each additional cycle adds approximately 15 minutes to the overall time)

Note that 1 is the normal 1 rinse cycle. (In this example the total cycle time is 50 minutes)

For this example 2= 66 minute,

3= 82 minutes, 4= 98 minutes, 5= 2h (114 minutes)

Page 15

Control- Features

Spin

Cycle

The control can add or subtract spin time by scrolling through the OPTIONS pad

after the Spin cycle has been initiated.

The increments are smaller and the logic is different. Customer can increase spin time up to 16 minutes, and decrease down to 5.

Page 16

Control- Features

ULTRA CLEAN

Maximizes detergent efficiency by adding water in steps and slowly diluting the detergent to the standard level. The machine partially fills, (appx 75%) then begins to agitate for approximately 30 seconds. Pauses and continues fill for about 10 seconds, then agitates. It repeats this process, in varying degrees and stages, 4 times before the tub is at the correct water level and the machine completes the wash cycle. Display alternates between

UC and time remaining. (It is the only cycle with a pre-programmed 2

rinse)

TEMP

Warm setting will highlight both COLD and HOT indicator lights

HEAVY DUTY

Adds 5 minutes to selected wash cycle.

Page 17

CONTROL

LOCK

Only locks the control “during” a cycle. Does not lock the control in the standby mode.

Press and hold “LOAD” and “OPTIONS” pads simultaneously for 3 seconds while machine is in a cycle. Display alternates between CL and

time remaining.

Control- Features

START PAUSE

OPTIONS led flashes while operating, and stays constant during “Pause”.

Page 18

Control- Features

LOAD SENSING When the control is first powered on, it defaults to “LOAD SENSING”

fill. (No “LOAD” size LED lights are lit at this time) The customer can change any of the TEMP, OPTIONS, or CYCLES selection and load sensing remains active. If the customer selects a specific LOAD size

manually, LOAD SENSING is deactivated

and the pressure sensor fills accordingly. If the customer leaves load sensing active and presses the START pad, the machine calculates the load while all of the load size lights alternate turning on. Once calculated the appropriate load size LED will be displayed. (The Pulsator rotates in both directions approximately 3 times to calculate load weight.)

Page 19

Load Sensing

Weight Recognition Function (Load sensing)

• The weight recognition function measures the washing load before water is supplied.

• The weight recognition function is canceled when water level key is pressed prior to the completion of weight recognition function.

• If the current water level is above the lowest level at the beginning of weight sensing, it is automatically set as a high level.

• If you change wash cycle after sensing weight, the high water level is automatically selected regardless of the water level decided by the sensing of weight.

• The pump runs whenever the washer is in the spin function of a cycle.

• The drain pump runs if water reaches overflow level and the washer is plugged in.

• The pump is capable of eliminating 4 gallons (15 liters) per minute

• The pump motor has an approximate resistance value of 11.8 Ω.

Page 52

Drive Motor & Belt

The motor assembly consists of a reversible, AC motor. The motor drives the shaft assembly pulley with a V-belt.

If the outer tub is not removed as an assembly, to access the belt, the washer can be carefully placed on its front or side.

The drive motor is attached to the platform with two 13-mm bolts. To replace it requires removing the belt, two 13-mm (33/64” SAE equivalent) bolts, and the Phillips-head screw that attaches the motor wire harness to the platform. The motor can then be lifted from the platform.

To the remove belt, loosen two motor bolts, and slide the motor toward shaft assembly

Page 53

Drive Motor

On the motor plug, check for approximate resistance values:

• Blue to white and yellow - 5.5 Ώ

• Red to white and yellow - 5.5 Ώ

• Blue to red - 11 Ώ (Can also be measured at PCB CN4 to CN5)

Blue wire is for the start winding.

Red wire is for the run winding.

The drive motor utilizes a 42 µF condenser. The condenser is a start capacitor. If the condenser is open; the motor will hum, but not start.

The condenser is attached to the platform with 2 Phillips-head screws.

Page 54

Drive Motor - Testing

Motor voltage and resistance can be tested at the PCB.

• Test for 120VAC from yellow to blue

• Test for 120VAC from yellow to red

If the output voltage is present at the board, when the motor should be running, the PCB is operating properly.

Page 61

Brake Motor

During a normal spin mode that is not interrupted, the basket will coast to a slow stop without the use of the brake control motor.

However, if the lid is opened during a spin cycle, or power is lost, the 120 VAC to the brake control motor is stopped, the gear engaged, and the basket stops immediately.

Diagnostic tip: The brake control motor and pump are always energized at the same

time. Therefore, if the pump is running, the board is working properly and supplying 120 VAC to the brake control. An open brake control motor will allow the pulsator to turn during spin, but the basket will remain stationary. This will result in wet clothes at the end of the cycle.

The brake control motor has an approximate resistance value of 1.4K Ώ

Note: Before weight sensing test is initiated, make sure that no water remains in the

washer. If water is remaining in the washer, inaccurate data will be displayed, or the

test will not proceed. To pump out, repeatedly press START/PAUSE pad until S

appears in the display.

With no clothing in the tub, when placed in the HA test, the following occurs:

1) Weight sensing begins.

2) Weight sensing ends, only the appropriate load light stays lit, and the display

shows corresponding weight sensing data.

The load light will indicate load size. Adding additional dry clothing, (not water) will decrease the data number as weight is increased. Data readouts are approximate

Extra Small = 97 and higher,

Small = 89-96,

Medium = 82-88,

Large = 76-81,

Extra Large = 75 or lower.

If the Soak light remains lit, 100 will be added to the display number.
