240 V ac applied to 120 V model!
Does the jug have an internal fuse? What is the likely damage in this case?
Browsing for this i found, after searching for '120v' in the amazon comment section that it is only made for 120v.
Also found a disassembly video on this particular thing..
Since i'm not a owner of such a thing i can't say what's inside, but if you're handy, and if it's broken, you can probably disassemble it yourself and check if there's any fuses.
