A low noise level was the key factor when purchasing my first dishwasher. I was impressed with the noise rating of the Profile Series 18 inch washer and it is very quiet.
After I bought it --but before having it installed -- I came across comments complaining that dishes do not come out dry. The owner's manual clearly states that the door must be opened immediately after the cycle is finished in order to dry the dishes.  That is what I do and I have had no problem with wet dishes.
