Actually the 155 is not a compact. It was Miele's biggest wringer washer, they are bigger than the Maytag wringer washers. There is a compact, that's the 65. Then there is a model that came out later and was available with all kind of options. That model is the 75. Options were a heater, a pump and on the TOL model there was the 75T, that had a timer controlled by the thermostat. The machine started agitating as soon as the desired temperature was reached.
