Help! My Frigidaire won’t drain after the wash cycle is complete. It was installed in 2002, I have not installed a new disposal, & the is no obstructions. I replace the drain valve & solonoid to no avail. Any ideas? 
What did you replace? I did not find the drain valve nor the solenoid on your dishwasher parts list.
I would recommend to remove the drain pump and check it and the drain hose for a clog.
Here are the break down diagrams for the Frigidaire dishwasher Model FDB635RFR5

I’m an idiot Gene! I found a blockage. Appeared to be mashed potatos! It was the drain pump I replaced (for nothing). Thanks for the help!
I’m glad you were able to fix it.

Hi Frank,
In order to provide most accurate advise I need the complete model number of the dishwasher.

Like mine, you might not see the obstruction. Take the hose off at both ends & try blowing air through the line. If you can’t, obviously you have a blockage. Don’t do what I did though! Drain as much water out of the unit before you disconnect it at the dishwasher! This way you won’t end up with water all over the floor & dripping into the basement!
