Introduction Theory of Operation Pressure Switch (Located inside control cabinet) Electronic Control (Mounted to back side of control panel) 3 2 1 Mixing Valve Belt Inner Basket Outer Tub Inverter Control (Mounted to base of washer) FLW1766S Electric Drain Pump (or Drain Valve) Motor General and requires less laundry detergent and less water. This frontload washer provides some of the same principles of operation as the typical topload washers.
Introduction The agitate cycle tumbles the clothing in a clockwise direction for a period of 15 seconds, pauses for nine seconds and then tumbles the clothing in a counterclockwise direction for 15 seconds. This agitation continues until the end of the wash cycle. The machine stops agitating and turns on the pump or drain valve which removes the wash water. Upon completion of the wash cycle, the machine goes into a rinse cycle.
