INTRODUCTION

The WM2496 washer and dryer are very similar to the previous series, with the

exception of the re-shaped front panel and the convertible dryer control. The

WM2496 machines are specifically designed to be sold as a stacked product,

and the dryer is delivered with the control panel mounted at the bottom of the

dryer. This causes the washer and dryer control panels to be adjacent when the

products are installed and stacked. Of course, they can be installed in a standard,

side-by-side configuration with the dryer controls mounted at the top of the dryer.

FEATURES

LARGE CAPACITY

The larger drum (4.0 cu. ft.) allows washing of

larger (heavier) loads and oversized items

(comforters, curtains, blankets, etc.) There is less

wrinkling and tangling of the laundry.

DIRECT DRIVE

The brushless DC motor drives the drum directly

without belts, pulleys, or transmissions. The

maximum spin speed of 1,150 RPM extracts more

water from the laundry, reducing drying times.

TILTED DRUM/LARGE DOOR

The tilted drum (10°) and large door opening allow

easier loading and unloading.

ROLLER JETS and BALLS

The baffles pick up water as the drum turns and

allow it to pour through the clothing as it tumbles.

The balls enhance the washing performance while

maintaining fabric care.

AUTOMATIC LOAD DETECTION

The microprocessor reads the current required to

turn the drum and determines the weight of the

load. This input is used to make numerous

decisions during the wash cycle.

FEATURES, continued

BUILT-IN HEATER

The internal heater helps maintain the water

temperature at its optimal temperature for

selected cycles. The SANITARY cycle kills most

common germs and bacteria.

CHILD LOCK

This allows the user to lock the controls. Children

then cannot play with the buttons and disturb the

wash cycle.

REMOTE LAUNDRY MONITOR

Available separately, the remote monitor displays

the cycle and remaining time on the washer and

dryer. It can be plugged in to any outlet in the

house.

WARRANTY

WM2496H*M Page 9 of 58 TRAINING MANUAL

SERIAL NUMBER IDENTIFICATION

The serial number is unique to each product. It gives information concerning the

time and place of manufacture. The serial number is required to be paid for

warranty service and to get the correct part in the event a running production

change was made. Some models may have four (4) letters instead of two (2) for

the product code number. The third and fourth letters are significant only to the

manufacturing facility.

This chart will help you decode the serial number.

FUZZY LOGIC

To get the best washing performance, the user selects one of the standard

cycles and sensors in the WM2496 make an infinitely variable number of

adjustments as the cycle progresses. Adjustments are automatically made for

load size, incoming water temperature, soil level, rinses required, and other

variables.

DOOR LOCK

The door has an automatic, electrically operated lock system. When the machine

is off or paused, the door can be opened by pulling it. When the machine is

operating, the electric latch keeps the door closed.

The door cannot be opened:

•When the WM2496 is operating

•When the power failed or the washer is unplugged

(until the capacitor discharges and releases the lock)

•When the DOOR LOCK light is on

•When the drum is still turning

DOOR LOCKED LAMP

The DOOR LOCK lamp lights:

•When the WM2496 is operating

•When the water level sensor frequency is lower than 22.9 kHz

•When the temperature inside the tub is over 45° C (113°F)
