Not really. In most jurisdictions, only gambling type sweepstakes (ie a random draw) are governed that tightly. Fan voted things like this are more or less unregulated. Plus, you have to read (and understand) the legalese fingerprint fine print to determine legal responsibilities. I’d be surprised if there weren’t language in there a that absolves them of almost all legal responsibility.

Also, there’s nothing in there that seems to be anywhere near an actual legal problem.

Assuming my setup is typical, the dryer is on a 240V circuit. The washing machine is on a 15A 120V circuit.
