  • Page 4: Introduction

    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.

  • Page 6: Features

    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.

  • Page 7: Display And Controls

    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.

    WARRANTY WM2496H*M Page 8 of 58 TRAINING MANUAL...

  • Page 9: Serial Number Identification

    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.

  • Page 10: Fuzzy Logic

    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.

  • Page 11: Water Circulation

    WATER CIRCULATION The recirculation pump circulates the water during most of the cycle. During the WASH cycle, it runs continuously for the first 3 minutes and then intermittently throughout the cycle. During the RINSE cycle, it runs continuously as soon as the appropriate amount of rinse water has been added.

  • Page 12: Parts Identification (Callout)

    PARTS IDENTIFICATION The air vent on the back of the machine must be left open and clear at all times. If the washer is installed in a closet or closed laundry alcove, there must be sufficient clearance and ventilation. The closet should have a full louvered door with at least 350 square inches (0.5 m ) of open area for ventilation.

  • Page 13: Accessories

    ACCESSORIES The washer comes with the two input hoses. The blue stripe is for cold water and the red stripe is for hot water. While the hoses appear to be mechanically identical, the temperature and pressure ratings are different. It is critical to the performance of the washer to have the hot and cold hoses connected correctly.

  • Page 14: Remote Monitor And Modem

    REMOTE MONITOR and MODEM The remote laundry monitor (RLM) allows the user to monitor the progress of both washer and dryer, provided they are both equipped with a modem. Remove the cover and install the modem on the back of the washer. Save the small socket cover and screws in the event you need to remove the modem for some reason.

  • Page 15: Installation

    INSTALLATION REMOVE THE SHIPPING BOLTS. INSTALL THE WASHER ON A FIRM, FLAT SURFACE. ADJUST THE FEET TO BE LEVEL. If you’re installing the washer on a pedestal, install the pedestal now. (See next page.) WM2496H*M Page 15 of 58 TRAINING MANUAL...

  • Page 16: Pedestal

    INSTALLATION (PEDESTAL KIT) This procedure covers installing and leveling the 7½” and 13” pedestals for 27” washers, dryers, and combos. If the products are stacked, the washer must be below the dryer, and you’ll use only one pedestal. Remove the pedestal, installation hardware, and instructions form the shipping carton.
  • Page 17 PEDESTAL, continued Depending upon the model, your pedestal may have straight or curved brackets. The curved ones are to be used on the rear positions when mounting a dryer to a pedestal, but can also be used in any other position on the pedestal.

  • Page 18: Connections

    CONNECTIONS WATER Be sure the rubber washer is inside the hose end. Attach the hoses to the washer (red is HOT, blue is COLD). Tighten them firmly but don’t strip the plastic threads on the washer connections. The hoses may appear to be mechanically identical, but the hot hose is rated at a higher temperature and burst strength.

  • Page 19: Program Chart

    PROGRAM CHART This chart shows the components and their times of operation in the various wash cycles. The time estimates shown here are for the basic cycles before the fuzzy logic adjustments are made. BEFORE PERFORMING SERVICE • Be careful to avoid electric shock when disconnecting parts for troubleshooting.

  • Page 20: Dispenser

    DISPENSER The dispenser drawer is a multi-chambered reservoir that allows the user to add all the appropriate laundry additives before starting the cycle. It has a place for pre-wash detergent, main wash detergent, fabric softener, and bleach. Powdered or liquid detergents may be used, but softener and bleach must be liquids. Detergents should carry the HE designation.
  • Page 21 The dispenser works by using various solenoids to apply water to different compartments. The liquid products are dispensed from a siphon box. As the appropriate chamber is flooded, the box fills and the water flushes the laundry product into the tub. It is mixed with water before contacting the laundry to prevent spotting or damaging the fabric.

  • Page 22: Test Mode

    TEST MODE The WM2496 washer must be empty and off to enter the test mode. 1. Press and hold NO SPIN and LIGHT SOIL LEVEL. 2. Press POWER. 3. Press START/PAUSE to cycle through the test modes. (See chart.) CHECK SUMS WM2277H* 1F:81 WM2077CW...

  • Page 29: Spinsense (To Resolve Vibration Issues)

    SPINSENSE SpinSense is a software adjustment that allows a small adjustment in the spin speeds to eliminate excessive vibration, particularly vibration caused when the selected spin speed strikes a harmonic value in the floor and causes resonance. To adjust the spin speeds to eliminate this issue, apply SpinSense using the following steps.
