Hello everybody, I got a call on a 1-1/2 year old Kitchenaid dishwasher model no: KUDS30FXSS0 & serial no: F04703336 that won't always run thru the complete cycle. It will shut off before the dry cycle. I ran the diag. cycle and got a 6-4 error code. Followed the tech sheet for that code, checked overflow float-OK, water valve-OK, electronic control board F9 fuse-OK. The only thing I found was that there was no drain hose loop under the kitchen sink. So I installed a drain loop as high as possible. My customer called and said the dishwasher will run all the way thru about 2 out of 5 times. If anybody has ever had this problem and could tell me what to do I would love to hear from you. Thank You very much!
