Moldy smelling clothes
First, clean your washer with one of the front load washer cleaners on the market. (Affresh, washer magic, smellywasher cleaner, whirlaway hot tub cleaner, or Tide front load washer cleaner) Use the longest, hottest cycle your washer has, with no clothes.
Second, rewash the smelly clothes with the heavy wash cycle and a second rinse option, using no soap or fabric softener. This will remove the soap and/or fabric softener build up in the clothes which is causing the smell. Third, begin using one to no more than two tablespoons of HE soap per load, and not more than 1 teaspoon full of fabric softener if you use it. This is because top load washers used up to 45 gallons of water per load, and your front load machine is only using about 12 gallons total. If you are washing a load of bath towels (which were only used to dry off your clean body, not wipe up the floor or something like that) they are not really dirty,...... for washing "clean" towels, don't use any soap, and of course never use fabric softener on towels.
