I’ve never done this but I heard about it. Instead of totally removing the end cap and discharge hose, you can poke a hole in your discharge flex hose. Then go through the hole with the garden hose or any other soft flexible ram. You can then snake it up the onboard plumbing. If you are successful in breaking up the blockage, the hose is still hooked up and will prevent a huge mess. The downside is the discharge hose will be junk once you cut a hole in it. Could save a lot of cleanup if it works.
