The machine works on both washing and drying. goes through all the motions. Washer fills, rinses, empties, etc. Dryer heats up and runs etc. Problem is that throughout all of this the drum does not turn or spin. Brushes in motor appear not to stick and still have plenty of wear in them. I did use the machine quite heavily for a couple of days doing some dyeing just before the problem arose. Anysuggestions on what the problem might be?
