I found the service data sheet which shows the normal cycle water consumption is 6 gallons. The same sheet shows the timing diagram and on the normal setting there should be 5 water fills. That's about 5 quarts per cycle. I put it back in test mode and filled it with water. The water stopped close to the 87 seconds and was about 1/8 inch high on the float. I cycled the water out and manually filled it with 5 quarts. It's very close to the same height on the float. So, my water valve is ok, it heats the water fine, shiny new recirculation pump, and the system is clean. I used cascade complete liquid in the main chamber, citric acid powder in the prewash, and finish rinse aid. The result was decent, and actually cleaned a black plastic ladle free of white stains left from previous wash cycles. However, a pyrex dish that was used to cook eggs was still bad and a cookie sheet used to make enchiladas still had cheese stuck to it. Both were on the bottom rack. We have hard water and for the last year it has been full of white minerals. Before we started using the citric acid, everything was coated with a white residue that was extremely difficult to remove. This washer has never been that great, nothing close to the old whirlpool that we removed. The main control board was replaced twice under warranty and the water pump once.

Ok, I read the points. My water hardness is 23 before the water softener. I did have old powdered soap, and it's in the trash now. I'll have to find a thermometer that will read 120, however, you can't hold your hand under the hot water tap. You stated put the citric acid in the tub. That will be drained out within the first 7-1/2 minutes on the normal cycle. So, how does the prewash bin work? Does the solution placed in the prewash simply start dumping as soon as you close the main door? It looks like the dispenser solenoid fires twice, and I'm not sure why. See attachment.
