LG & Samsung Washers: Why the Door Seal Grows Mold First
By Vent Pro NYC · · 4 min read
Half the calls we get start with a brand name. “My LG has black spots on the door seal.” “My Samsung smells musty no matter what I do.” And underneath the question is usually a worry: did I buy a bad machine? So let’s settle that first — no. LG and Samsung are simply the two front-loader brands we see most in Brooklyn laundry rooms, so their gaskets are the ones we’re most often elbow-deep in. The mold isn’t a defect. It’s front-loader physics, and every watertight door on the market plays by the same rules.
What these machines have in common
A modern high-efficiency front-loader seals its door with a deep, multi-fold rubber boot and washes with far less water than the top-loaders most of us grew up with. Both are genuinely good engineering — better cleaning, lower bills — and both feed the same side effect: low-water cycles leave more detergent residue behind, and deep gasket folds hold onto a little water, lint, and that residue after every load. Damp, dark, and fed is mold’s whole wish list, and it’s the same list on an LG, a Samsung, or anything else with a watertight door — here’s the full mechanism.
The manuals quietly agree
Dig into the care section of either brand’s owner’s manual and you’ll find the same advice we give at the end of every visit: wipe the door seal, leave the door ajar between loads, run the tub-clean cycle regularly, and use HE detergent in the right dose. The manufacturers know exactly how their gaskets behave — the instructions just live on a page most owners never reach until the smell shows up.
What actually fixes it
Exactly what fixes it on any front-loader. A light case is a DIY job — soapy water, a soft brush, and every fold, walked through in our DIY guide. An established colony that keeps coming back is our job: one focused visit, our four-step treatment worked into every fold, and the 20-second habit that keeps it from starting over. We clean LG and Samsung gaskets the same way we clean every other brand’s — thoroughly, without harsh chemicals that dry out the rubber, and with an honest read on what staining will and won’t fade.
