I bought the Kitchenaid Superba dishwasher seven years ago after researching the available units on the market. I chose the Kitchenaid Superba model because of the features, price, and reliability of the brand. I needed a reliable dishwasher that was sturdy and would stand up to abuse from children and heavy washing. The Kitchenaid Superba has been very reliable so far.
We have had only one mechanical problem since we bought it in 2001. The water inlet valve is worn and needs to be replaced. This repair is inexpensive and we will be doing it ourselves after we get the part.
The dishwasher does wash dishes very well and it is easy to use. I am able to wash pots, pans, and baby bottles easily. There are several cycles available to choose from and I am able to do all types of loads from heavy washing to quick rinses. The front panel has the controls on it at the top of the door and the cycles are set by pushing buttons. The only thing I dislike about the dishwasher is the location of the on and off buttons.
They are located right on the front of the dishwasher door and are within extremely easy sight and reach of small children. If the off button is pushed while the cycle is running it resets itself and you can not turn it back on at the point in the cycle where it left off. The only option you have is to restart the dishwasher from the beginning.
Overall, I like the dishwasher and it has been reliable for our household. I would buy it again.
