3-1. LOAD SENSING
1) Deciding the water level
ῡ
Normal, White, Eco-White Course will be followed by this process.
ῢ
Check the water level with dry laundry at the starting wash.
ΰ
Check the water level by using motor output data during 20 sec, 65rpm.
2) Deciding Spin Starting Step.
ῡ
Check after finishing washing step with wet laundry.
ῢ
Checking by using motor output data during 20 sec, 65 rpm.
ΰ
The Decided data is different depending on loading condition.
3-2. Balance Spin
1) Motor running during balance spin
ῡ
Spreading the laundry : Rotating the same 45 rpm with left and right direction alternatively.
ῢ
Unbalance checking point : first step, sheck the U.B at 95 rpm, 160 rpm second step, check the U.B
at 95 rpm 350 rpm.
Third step at 300 rpm. If the unbalance data is over the criterion
This process will be repeated.
ΰ
After drain, check the unbalance data again. This is so-called balance spin step.
3) Property of balance spin
ῡ
Conducting 20 times maximum.
ῢ
If the washer can not pass balance spin step during 20 times, then water will be supplied.
