OK, I am embarrassed to say that the reason why I thought the rinse cycle was anemic was because I was turning the dial too far past the cycle start indicator. So what was happening was I was passing the period where the valve was opening to let the water enter. The gurgling was the pump just trying to spray an inadequate volume of water that was left from a previous cycle I guess. I was wondering why dishes were still getting clean if the inlet water valve was faulty.
Here is how I discovered my error. Based on all of the advice given, I did the ohm meter check and it read OK at ~1200ohms. I then went back and while doing one of my door bypass checks I actually caught the beginning of the cycle and saw the water entering from the side of the dishwasher wall. The video was key to letting me know where to look.
I then did a test where I positioned the dial at the beginning of each cycle and every time, after less than a minute, I could hear the inlet valve open and water hissing in. Shortly after I could tell a full volume of water was being sprayed around. this confirmed that everything was working fine and the problem was operator error.
Thanks folks for all of your help and sorry for the false alarm. Hope someone will read this and learn from my mistake.
