#4 is best if you run the dishwasher frequently, have not too hard water, and good quality tabs (or whatever these cleaning agent thingies are called).
We had to exchange the dishwasher three times in 20 years (each time, a model from the lower end of the price range with good independent test results). I have tried repairing it two times; one success (the pump thing is cheap). Mostly the pump breaks down—presumably from too much of the wrong stuff.
