This dishwasher was installed new 2/27/2007. It worked well up til about a couple of months ago, but hasn't been perfect in my eyes since new. I have to put 1/2 the dishes etc. in 2 or 3 times to get them clean. Our water runs very hot, i am using correct detergent and jet dry in the dispenser provided for it. Please help. My extended warranty doesn't go into effect until 2/23/09. I could call for service now, but would like to see if I can solve it myself first. Thank you.
