Miele professional dryers require 2x 208v or 3x-208v at 60hz
Professional washers are at 2x - 208v at 60hz.
At 2x (208v) we're talking 2x 30amp fuse rating and 3x same for 3x 208V.
Either way believe me when I say neither washers nor dryers have any trouble reaching and or sustaining high wash or drying temps.
