■Jumbo drum
Westinghouse’s jumbo drum can wash about 40% more per
load than conventional washing machine. A bigger drum
improves the wash performance.
■Protection against wrinkles
With the alternate rotation of the drum, wrinkling in the laundry
is minimized.
■More economical by Fuzzy Logic System
FUZZY Logic System detects the amount of load and water
temperature, and then determines the optimum water level
and washing time to minimize energy and water
consumption.
■Child-Lock
The Child-Lock system has been developed to prevent
children from pressing any button to change the programme
during operation.
■Low noise speed control system
By sensing the amount of load and balance, automatical
distributes load evenly to minimize the spinning noise level.
■Auto Restart
Although the washing machine is turned off by a power failure,
it restarts automatically where it stopped when power is
supplied again. and it will be the same the machine is
unplugged and is plugged in again.
