Well it appears that no one knew the answer to my question. The good news is that I broke the code and found the elusive screw on this particular part that controls the water level.
After searching the internet, I saw a short post from a parts rep that told a customer that the adjustment screws are under the wax seals. Armed with that knowledge and knowing that the four exposed screws didn't control the water level, I returned them back to their original settings.
Below is a picture of the part with an arrow indicating the seal where the water level screw is located. I removed the seal and turned the screw one full turn (clockwise). Voila!!!! The washing machine adds an additional 5 gallons of water during the wash and rinse cycles.
more water means...
- cleaner laundry with no funky smells
- the extra water fully flushes out the hoses and drain reservoir so no residue and no stagnant water is cycled back through my laundry
- Pa-pow! my work here is finished
