■Jumbo drum
Jumbo drum can wash about 40% more per load than
conventional washing machine. A bigger durm improves the
wash performance.
■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, evenly
distributes load to minimize the spinning noise level.
■Auto Restart
Although the washing machine is turned off by a power failure,
it restarts automatically in its stopped process when power is
supplied again. and it will be the same when the machine
unplugged in operation is plugged in again.
