  • Page 7: Out Of Balance Switch

    The Out of Balance Switch controls the motor operation during the Catalyst Cleaning portion of the cycle, as well as during the spin. If an out of balance condition occurs during Catalyst Clean, the motor circuit is interrupted. The motor will stop momentarily to allow the load to settle, then restart. If the Out of Balance Switch is actuated four times, the Electronic Control will skip the Catalyst Clean cycle and jump to the wash increment.
  • Page 8: Balance Ring

    The additional ballast is required to counteract the clothing load during the Catalyst Cleaning mode. The ring is attached to the spin basket and is not available as a separate component.
  • Page 9 The dispensers allow the additives to be introduced to the laundry load at the proper time in the cycle. A diverter is molded into the tub ring to push the dry clothing into the basket during the Catalyst Clean- ing portion of the cycle.

    Section Two THEORY OF OPERATION CONTROL PANEL Fig. 2-1 OPERATING THE CLOTHES WASHER Choosing Cycles Use the SELECT CYCLE keypads to choose the wash cycle for the type of fabrics being washed. Fig. 2-2 GENERAL INFORMATION The Electronic Control allows the consumer to add or subtract agitation time in all cycles. •...
  • Page 12 WHITEST WHITES Detergent and bleach are dispensed at the proper time for the best possible performance. This cycle introduces liquid chlorine bleach sooner to the load than the other cycles for improved whitening of heavily soiled white fabrics. The default motor speeds for agitation and spin are both high speed.
  • Page 13 Use the OPTIONS control to select the desired options for the wash cycle. CATALYST CLEANING™ CATALYST CLEANING™ allows detergent to soak and penetrate the entire load giving im- proved stain and soil removal. This option will last one (1) to five (5) minutes depending on the cycle selected.
  • Page 14: Water Level

    WATER LEVEL Up to five (5) different water levels can be selected ranging from SMALL LOAD to LARGE LOAD. In most cycles, reducing the water level will result in the motor operating at a slower agitation speed. See chart on page 9. WASH/RINSE TEMP CONTROL This allows the selection of four (4) different wash and rinse water temperature combinations based on the type of load being washed.
  • Page 15: Operating Controls

    Operating Controls Press the START keypad to start the washer after a cycle has been selected. Press the PAUSE/CANCEL keypad to pause or stop the washer at any time. Press the START keypad to complete the cycle from where it was stopped. Press the PAUSE/CANCEL keypad twice to turn the washer off.
  • Page 16 • If Spin Only is added to any cycle, it becomes an additional 4 minutes of spin. • Soak will provide both some agitation and spin. • Catalyst Clean is selectable in all cycles except Quick Wash and Hand Wash.
