OH! I love these machines!! I don't use mine regularly but it does a decent job in my opinion.
The trick with these machines is that it is not automatic... The operator of the machine controls when the machine fills, how long it washes, and when the machine drains. I'm not sure if the operating instructions came up in the Automatic Ephemera library already...
The 'basic' operation suggested was a 5-minute wash followed by 2 rinses (I think it was suggest to rinse for 2 minutes). When I used the machine, I gave dis hes a 5-minute prewash, two 4-minute rinses, a 9-minute main wash, then three 4-minute rinses. Don't forget that you'll have to add detergent manually when you want a 'wash' period in the cycle.
Oh, and there is no heated dry with this model; you just open the lid and let the dishes air-dry.
Hope this helps!!
