Brand new, can't take back I just can' make it work
Call the manufacturer. They should have a help line.
What's not working on it? If it has never worked, I'd call the company and then take it back if they can't help you get it working.
There are several videos on YouTube here's one that might help...
Is it heating water? Are you using brand specific k ups or generics? Do you know that the k Kcups are actually instant coffee? Not brewed? I’d take it back to the store and check the coffee isle for the flavored coffees.
Does it not work on only one electrical outlet when plugged in, or on other outlets also?
The breaker on the outlet may need to be reset.
