This issue has only recently arisen, and it occurs during all wash cycles. If "Quick Rinse" is chosen, the unit DOES fill with water. I measured the voltage at the fill valve during the rinse section of the wash cycles, and it is 114 VAC. When the unit fills with water as it should, the fill valve receives 118VAC during "Quick Rinse." During the balance of the time, the unit fills and drains normally. I manually filled the machine with water, and the rinse cycle continued as usual, pumping and emptying.
I didn't think a 4 volt voltage difference would prevent the fill valve from working normally? According to what I've read, insufficient voltage at the fill valve is caused by a faulty control board. Is it conceivable that I have a faulty control board as well as a faulty fill valve?
Thank you in advance for your feedback and suggestions!

Before removing the bottom access panels, make sure the dishwasher is turned off. I have to believe the drain pump is stuck or defective based on your symptoms and data. Remove the front bottom access panels and inspect the drain pump for any obstructions. If your drain pump hums instead of operating and pumping water out, it's most likely because it's not getting enough electricity (120). It is simple to remove the drain pump and inspect it for any blockages. Check the fill valve as well.
If it looks like everything is in order. There's also the issue with the control board. We can fix control boards that have malfunctioned.
I hope you find this information helpful.
