I never thought about the baffles being smaller would account for the more space. They way they word it, is that they actually made the drum grew larger.
I really can't see any reason for the 240 volts. There is a test run that you can do with these washers. I did it on mine. It is a service test sequence that you do with the buttons, that turns it into a service mode. When you do this, it only puts in cold water. Then the tub only turns in one direction through the entire test with cold water in the tub. Then the heater kicks on, and heats to the sanitary temp. It took only about 12 minutes the two times I ran the test, for it to get to that temp. Then it drains, and goes directly into the high spin.
