We've been a bit spoiled, our laundry is behind a closed door in a mechanical room. We thought it was fairly obvious with our LG front loaders that the door would have to remain open when not in use. Yes, that could be an issue if you don't have them behind a closed door with kids or pets. Like @LMichaels we use softened water. It does pay to watch closely what detergent you use. We'd been using Costco's house brand HE detergent, and discovered that it still had some non-solubles that caused minor leaks somewhere. Switching to a name branded detergent has completely eliminated that issue. We also use far less detergent than you'd expect, but being a couple of professionals, our cleaning requirements are a good deal lighter than say a mechanic.
