kenmore elite dishwasher not getting enough water
My Kenmore Elite dishwasher 665.16912001 is getting only about 1/2 inch of water. The load runs but there is still powder in the cup and the dishes are not clean. I had my local repair guy in and he cleaned the water inlet valve, which was pretty mucky, but no improvement. If I stop during the fill and add about two quarts of water it works fine. I asked him about other repairs and he said that dishwashers today are almost disposable because they have only two major parts each of which cost $350 or more plus labor so most people do not want to spend that money on a dishwasher that is more than a few years old.
The dishwasher was working perfectly until a few weeks ago so it seems a shame to dump it just because we can't figure out what the problem is.
I have done the reset. On my machine is was-sani-rinse, air dry, 2x. A number 88 appeared in the timer area, all the lights lit up and then it checked several of the different settings for 10 minutes and shut off but there was no improvement.
