My loader is coming up with a f21 so we cleaned the pumps all out and there maybe something in the pepellier but we cant figure out how to take it off?:(

The impeller is very easy to clean. It is easiest if you disconnect the hoses and wires and remove it from the frame of the washer.

Flipping up the larger of two two rubber pads will allow you to push the pump to the right, and then up.

If you look at the pump, focus in on the part where the two round plastic pieces come together. Leave the box-like part of it alone.

The two round plastic pieces have a number of tabs and grooves. One of the tabs can be pushed aside with a small flat head screwdriver which will allow the other tabs to rotate. Rotate the pieces around 15 degrees and then you can separate them. You can then access the impeller from there. Be mindful of the o-ring.
