Anyone removed the splendide combo from an older Fleetwood?

Had a odor problem behind my washer in a 04 Southwind. The vent valve was ok. The problem was the drain hose had worked it's way down the drain pipe into the pea trap which did not allow water to stay in the trap to block odor, as soon as I poured water down the drain the odor when away. Repositioned the hose and solved the problem. I was lucky on my model and was able to slightly open a panel behind the unit. May not be your problem but something else to check.
