  • Page 3: Front Loading Washing Machine Basics

    Front Loading Washing Machine Basics 1. Front Load Theory Front loading washing machines get laundry cleaner and use less water than top load machines. Cleaning is achieved with the mechanical action of the drum lifting the laundry up and dropping it into the wash water in the bottom of the drum.
  • Page 4 rum Wa 4. Major Functions ① Washing The laundry is tumbled during the wash cycle by the rotation of the drum and the drum paddles. This process is more gentle on clothing than turning them with an agitator. ② Rinsing Rinsing cleanly washes out detergent and dirt removed from the laundry after washing cycle.

When draining is complete, 1 minute is reduced from the overall cycle. 2) Balance Spin ① Balancing the laundry : The machine will tumble clockwise and counterclockwise at 45r.p.m. During this time, the machine is calculating and trying to correct the level of unbalance in the drum based on the data from the load on the motor.
  • Page 30 rum Wa 3-4. Ending the program 1) Clothes release The motor is tumbled slowly to prevent wrinkling by loosening the laundry attached to the inner wall of drum after completion of main spin. Releasing is carried out for 30sec. 2) Ending After completion of the clothes releasing phase, the buzzer is sounded for 10 seconds and power is turned off.
