Finding/cleaning the filter
Once the washer is empty, you can prop up the front of the washer. (I use a couple of canned goods.) With the front propped up, you can undo the three screws that attach the front plate at the bottom-front of the washer. Remove the plate and on your right you'll see a cylinder with an inset handle on it. This is the cover of the filter. (Before unscrewing it, lay down some old towels to absorb any water that might come out.) Unscrew it counter-clockwise. (It can be quite hard to undo, be patient.) Pull the filter all the way out. You should be able to remove any items/gunk that have become trapped. I usually wash off the filter by hand with dishwashing detergent while I have it out. Reverse the instructions to put everything back together. I have two kids and have had to do this procedure about 3 or 4 times now. Works every time.
