Greetings!
Yes, the light indicators on this Samsung washing machine will turn on when in operation. The light will indicate which part of the wash cycle the machine is currently on, which temperature the water is set to, how much rinse, spin power, etc. The washing machine has a display screen where it will provide information codes if a situation occurs like when the door is open. When the door is open, the code DC will show on the display screen.
