I had an error code for my Frigidaire Affinity washer that alerted us the drain filter was clogged. Set the washer on its side, cleaned out the filter and re-connected everything, then the washer seemed to not recognize that the door was closed and would click, beep, and not run. We ran a diagnostic that gave us an E91 error, which I researched to mean, "Communication error between UI board and control board. Check wiring and replace the board if the wiring is good." The problem is I can't find any sort of tutorial or service manual to describe what needs to be done, nor can I find info on what part needs to be replaced. Model number is FAFS4073NA. Any ideas?

Here's the part you need:

It's the UI in the console. Here's what Frigidaire says: Replace the user interface board. If the problem is not corrected, replace the main control board.
