A:Answer210 to 240 volts,[ depending where you live ]@ 30 Amps. Same for all full size electric dryers. Ether a plug with 3 prongs or 4 prongs if it has a ground.
A:AnswerIts very quiet. Just make sure you level it well. Otherwise it can be pretty loud. took a few tries to get perfect leveling.. now its very quiet
A:AnswerGreat question- we allowed 10" however 6-8" would have worked for our configuration. The added water (steam) hookup via a splitter and venting are the largest space takers.

You can use an app for your phone that, in combination with the dryer, will display trouble codes to help you diagnose a malfunction.
