Sud and F35 Error still.

We have a Maytag 5000 series washer, MHWE500VW11. Recently we had the error message Sud followed by F35 when attempting to do a load of laundry. In the past year, we had this and the drain had stuff in it. This time, the drain was empty. Based on other posts, I ordered the water level switch and the hose for it as well. Installed it earlier this evening, and still had the same error codes. Tried to run a diagnostic and it didn’t get past C:00, error F35 came up. The pump appears to be working ok since the water comes out with a fair amount of force when the machine empties out the water. What other parts might need to be checked or replaced?
