If you do this, water supply will start immediately and it should operate as set.
However, like the automatic mode, it takes time to detect the laundry and supply water.
There are times when the water supply is low and the washing starts, so you have to come in the middle and set it again.
Because of this, it is very inconvenient to use and I do not want to use the Samsung washing machine due to stress.
At home, Samsung tries to condone this problem and move on.
It's very disappointing why large corporations don't take action on this issue.
