Miele Washer Smells Bad: Honeycomb Drum Cleaning and Mold Prevention

Quick Answer

Miele washers are LESS prone to mold than other front-loaders due to the Honeycomb drum design that allows better drainage and the higher-quality door boot seal. However, they can still develop odor from low-temperature washing. Miele recommends running the Sanitize cycle (95C/203F) monthly to kill bacteria and mold. This is hotter than any consumer brand's clean cycle.

Miele washers are LESS prone to mold than other front-loaders due to the Honeycomb drum design that allows better drainage and the higher-quality door boot seal. However, they can still develop odor from low-temperature washing. Miele recommends running the Sanitize cycle (95C/203F) monthly to kill bacteria and mold. This is hotter than any consumer brand's clean cycle. If odor persists: clean the door boot seal fold (same as other front-loaders), run the drum clean program with Miele descaler or white vinegar, and leave the door ajar between washes. Miele's specific advantage: the Proactive Water Management system drains residual water from the sump after every cycle, reducing standing water that causes odor.
