  • Page 15: 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 16 Water Circulation The recirculation pump is separate from the drain pump, but they are attached to opposite sides of the filter housing. When the sanitary cycle is used, the door will remain locked until the laundry has cooled to a safe temperature.

It liquids in place) has a place for pre-wash detergent, main wash detergent, fabric softener, and bleach.
  • Page 26 Dispenser 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.
  • Page 27 Dispenser Notice that the pre-wash and main wash fill tubes enter the dispenser at an angle. If one or the other fill valve is opened, the water goes into the appropriate detergent compartment. However, if they are opened simultaneously, the streams deflect and dispense the softener.
  • Page 28 Dispenser If liquid detergent is added to the pre- wash box, it will run immediately into the tub. This does not affect the operation of the cycle. To use liquid detergent in the main wash, place the detergent siphon box in the main wash compartment.
  • Page 29 Dispenser The siphon boxes are designed to hold a liquid laundry product until the appropriate time for dispensing into the load. When the box fills with water, it begins to discharge its contents into the washer fill stream. Once the siphon action has started, it will continue until the siphon box has emptied itself.

  • Page 58 Installation – Pedestal 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 59 Installation – Pedestal Holding the exposed adhesive away from the appliance, insert the screws and get them started. Then press the brackets to the appliance and tighten all the screws. Rub the bracket from side to side to ensure a complete bond.
  • Page 60 Installation – Pedestal Use the wrench to turn each leg of the appliance approximately ¼ turn to put a little pressure between the appliance and the pedestal. This will eliminate any rattles. It is usually easier to set the pedestal and washer into place and connect the water and drain hoses before placing the dryer on top of them.
  • Page 61 Connections 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 62 Connections The drain pipe should be firmly attached to the standpipe or the laundry tub or sink where it drains. The pump has sufficient power to cause the pipe to move around when the water is expelled. The pump can lift the drain water a maximum of 96 inches (2.4 m), but there is no minimum height requirement.
