Write to the company asking if they make a 220 volt version. If so, then they might sell you a new motor you can fit yourself.

At almost $400 dollars for the unit it'd be worth it.

Is it possible to get a dedicated 110 volt line in a European home (that would be hot/neutral/earth)? The 220 volt lines for low-amp stuff (15/20) here in the USA are hot/hot/earth.
