Does Aquarius 1100 washer dryer WD61 have a thermostaat to heat water to correct temperature? I have hot and cold inlet pipes but only the cold is connected. The machine is not washing poperly. On washing cycles C & D (90 & 50 degrees temp cotton wash) the machine will not fill and just makes a zooming noise. It will fill for all the other cycles includung the 50 degree sythetic cycle. This machine worked properly on the hot & cold water system but I don't have that now. Can anyone please help me? _
