Product review (3 stars): We were very disappointed in the performance of this dishwasher
We were very disappointed in the performance of this dishwasher.  We called GE customer service and they were very pleasant and forthcoming.  They advised that, because they have to meet energy efficiency standards, it's very difficult to make a dishwasher that performs as well as the older models most people are replacing. She advised us to be sure to run the hot water in the sink first to ensure that hot water is immediately being fed into the machine, and to be sure the drain is cleared before starting the dishwasher - especially if you have a garbage disposal.  I have since been letting the machine choose the setting, and my dishes are definitely getting cleaner than they were.  It doesn't dry well at all, but I just open it when it's done and let the dishes air dry.  I hope this helps other who have been disappointed in the performance of this machine.
