Your water level float is probably stuck. Take a look at this video and it shows you how to basically access this component. Use CLR to clean it out. Be careful to turn off your dishwasher breaker. Electricity and water do not mix well. Your dishwasher may be slightly different but Samsung dishwashers are pretty consistent in general as far as parts go. If you have at least basic mechanical skills you should not have any problem doing this repair.
Actually, if you look closely at that Low Rinse button or emblem, you will see a little lock symbol ABOVE the words "Low Rinse", and I'll bet THAT light is the one that is on. Basically, you have the control lock (or child-lock) turned on. To turn it off, you have to press and hold the SANITIZE button for 3 to 5 seconds until that light goes off. Now your dishwasher will work!
try this , but will be a good idea to get service support from Samsung. f
your dishwasher is new--or if you have just replaced a door seal--the
door may be difficult to latch for a week or two. If the tightness
persists, though, try adjusting the latch, if it's adjustable. If it's
not adjustable, there's probably nothing you can do immediately. But try
running the dishwasher on the highest heat cycle to help the seal
conform to the door. Otherwise, the seal should compress over time God bless you

The lights that are blinking are indicating an error code--the particular code you describe is a "heater error". You will have to check the circuit for an open heater element, loose or broken wire, defective main control board. The part number for the main board is DE92-02256C. Hope I helped you!
Make sure your circuit breaker in the main breaker box has not tripped, or "poped". It will be one a little out of place and a bit loose if it has tripped. Turn it off and back on to reset. If it tripps immediately, you have a short somewhere, possibly in the dishwasher, so you will need an electrician and or Appliance tec. to find and fix.
I believe that error code indicates that you've got a leakage error, which means water has leaked down into the base of the dishwasher. You'll have to pull the dishwasher out, pull off the side panels, and dry up all the water, but then you still have the problem of figuring out where the leak came from and fixing the problem before you can use the dishwasher. The most common source of leakage in a Samsung DW is the drain pump and/or drain hose.
