Pipe a dedicated line to the dishwasher?? Not happening here--I live in Florida, slab foundation & very large house where water heater is located in garage & dishwasher is in 'pass-through' between kitchen & family room at the rear of the house.
Besides, I think I found at least a good part of the problem---I decided to take my own advice (if you want it done right....). I just turned the dishwasher on to do a load overnight & decided to open it to see how warm the water was (after running the faucet to hot again & checking the dishwasher line & feeling that it got very warm too). Strangely enough, even though the water supply hose for the dishwasher was very warm, the water in the dishwasher was cold (72*) immediately after it filled. But I noticed that the water didn't cover the heating element & in fact was about 3/4" below the element! I don't know why it wouldn't fill any more than this---the float didn't even lift off the bottom.
It is the heating element that heats the water in the dishwasher, is it not? There wouldn't be any other heater inside that would heat it would there?
Now the dishwasher has drained & filled twice & the water has been cold after filling every single time & it has not reached the heating element on any of the 3 fills.
Thanks again,
