I have a similar dishwasher to this, except it's an Inglis and has electronic controls. I restored it after it had been sitting in a barn for many years. Had to unseize the motor and eventually rebuild the pump, but it works pretty good now. The only complaint I have with it is the upper rack-I find it doesn't wash as good as it should, and it leaves particles of food on stuff, especially my cereal bowls. The lower rack cleans anything I throw at it, but the upper rack suffers the consequences. I've had some improvement by adding salt into the detergent dispensers with the detergent, which softens my very hard water, but I'm wondering the same thing that Kenmore71 is in that if more water would get to the upper rack if it weren't for the center tower distribution system. I do use rinse agent and my water is hot enough I think (even if I use the heated water cycles, it doesn't seem to make a difference).
