it washes and spins according to the sensors.  i make sure all my clothes are in the washer evenly, nothing balled up. clothes are very clean and it spins very dry.
i use cold to wash everything…please note, samsung’s cold water adds hot water.  but it works for me.
i read the instructions and follow them and i have no issues.
you have to put your detergent in first, i use liquid and i pour it into the machine and put the clothes on top.  very big and deep tub.
this is a very good purchase.
