removal of faceplate to access screws to remove top panel cover

I need to access the pump to clean it out. I have removed the 4 screws at the bottom of the bottom panel but before it comes off you have to access the top screws which are under the front top panel. I cannot find how to remove the faceplate off the top panel to access the screws to remove the top panel…to remove the top screws to lift off the bottom panel. Any help out there?
