Frigidaire Model:FFBD2411N

Last week, my dishwasher would not drain. Checking first for a clog, I pulled out the end of the drainpipe and blew into it to try to clear out any clogs. It took a while but eventually it made it through to the dishwasher basin. But it still didnt drain.

I then removed the drainpipe and re-attached. I never found anything that would clog it. But when I reassembled it, it worked. But again yesterday it stopped draining again. But I would try to re-attach some of the wires and it would eventually work. But sometimes would stop in the middle of running, with two lights flashing or it all would go dark. Again, I'd "play" with the wires underneath a bit and it would eventually run through. I have no idea if any of my write-adjusting is having an effect or not.

Based on my search here, it may need a drain pump assembly replaced, but is there any other troubleshooting I can do before I go that route to be sure that is the issue?

Thank you for your time - I appreciate the assistance.
