Sometimes it's from the motor overheating but would need to know what kind of washer and model to help further.

If you have tried to unplug from mains power and there is no difference then you will need to provide the actual model number of your dishwasher in comments field.
The Samsung error codes for Normal, Heavy , Delicate lights stuck is not listed. The closest is Normal, Heavy, Quick which relates to a Low Water level. Also confirm which lights are stuck in your case and whether these are flashing or not.

when you unplug it you're resetting the computer board just like your house computer does,so if it helped by unplugging it i would have to say the board is bad and needs to be replaced.next time send the model number off of the machine

Yours is a 2 speed motor. Does it spin in 2 different speeds. If so, then it most likely is designed with only to agitate in 1 speed. If it only spins in one speed, then your motor is defective

Sounds like a logic board problem. You may have to change the logic board!

The washer timing control is defective.

I just ran into a similar problem. Ours was stuck on Normal with 42 min. Started beeping every couple minutes last night after bad rain storm. Couldn't get it to stop. it would turn off if I hit stop and a couple minutes kater (like 2min) it would come on by itself. Left it unplugged overnight until about 6:00pm. Plugged it back in and it wnt right back to the normal mode after about 2min. HOWEVER, I keft it sit with the lid open and it beeped every couple minutes for a while then suddenly stopped. I checjked it and it is off, hasn't come back on. I haven't tried to run a load through it yet, so I don't know if it is fixed or not..

sounds like the door switch
