GE GFW850SPNRS 5.0 cu ft Smart Front Load with Steam MECH-ODOR Error Fix: Mold/Mildew Odor on Clothes and in Drum

Error code MECH-ODOR on the GE GFW850SPNRS 5.0 cu ft Smart Front Load with Steam means: Mold/Mildew Odor on Clothes and in Drum. A musty, mildew smell is present inside the drum and on washed clothes — biofilm (bacteria and mold) has built up in the folds of the door boot gasket, in the detergent dispenser, and in areas where water sits stagnant; GE front load models with UltraFresh Vent help prevent this; for existing buildup: run a tub clean cycle monthly with washing machine cleaner or bleach; wipe the door boot dry after each use; leave the door slightly open between loads to allow air circulation; use only HE detergent in the recommended amount (excess detergent feeds mold)
