Samsung Samsung WA50R5400AW 5.0 cu. ft. Top Load Washer DOOR BOOT MOLD Error Fix: Door Boot Seal Mold Growth

Error code DOOR BOOT MOLD on the Samsung Samsung WA50R5400AW 5.0 cu. ft. Top Load Washer means: Door Boot Seal Mold Growth. Black mold has developed in the folds of the rubber door boot gasket on front-load washers. The gasket traps moisture, detergent residue, and fabric softener after each cycle, creating ideal conditions for mold and mildew growth. Symptoms include musty odor from the washer and visible black spots on the rubber. Wipe the gasket dry after every use. Clean with a 1:1 vinegar and water solution or use a gasket-specific cleaner. Run a monthly cleaning cycle with bleach or a washing machine cleaner tablet. If mold has penetrated deep into the rubber, the gasket must be replaced ($50-100 for the part).
