We tried cleaning out the filter and it clogged with a huge amount of gunk. We removed the gunk, scrubbed the filter, and tried running the dishwasher, but still no water.

Once the replacement arrived, I checked it and the flood switch rattled, confirming that it should work properly. I spent 30-45 minutes installing it, plus the filter assembly and racks I had to remove to access it. Ran the dishwasher and everything came out sparkling clean.

This indicates they both were working fine and no need for replacement. Next step would have been to swap the elements would have been ... Read more simple. Tried to replace main board as well, still not the issue so giving up and replacing the dishwasher. It wasn't the high temp cut off thermostat either incidentally and no error codes in maintenance mode. Check continuity of your existing element before ordering to save aggravation.
