Although this is my first time in hearing about the draining when you won't be home (to be safe, yes, I'd totally be up for it just to be safe), the drain is super easy to empty, but more importantly, it's part of your maintenance to keep your machine in top running shape! Not only is there a drain down there, but a filter too! This filter catches all sorts of gunk and grime. Both are a breeze to maintain.
Just get a saucepan, and a thick towel. Next, pull the short drain hose out from the clamp, and twist off the cap - OVER YOUR PAN!!! Hold the drain hose over the pan until it's empty. Don't be surprised at the amount of water in there, it's a good few cups!
Replace the cap, and re-secure the hose into it's spot within the clamp.
NEXT - the filter!!! Unscrew the filter and twist it out of the opening. Pull out the [plastic] filter and clean out any gunk that is trapped in that filter. It's fairly dry, but will be moist, most of it should come out without any issues, but you can give it a swish in the water being held in your pan.
Re-secure the filter by screwing it back into it's spot, and you're good to go! This should be done every SIX weeks to keep your Samsung washer running at it's best.
Just in case something wasn't worded right, here is a video presented by Samsung, on performing both jobs:
