The features that make HE washers more efficient also make them more vulnerable to odor-causing residue.
- Each wash cycle requires less water, so more dirt and detergent may be left behind.
- HE washers deliver outstanding cleaning in cold water, but dirt and grease are not fully dissolved and are more likely to leave a residue on the interior of the washer. It is important to use hot water cycles with appropriate loads of laundry to better dissolve soils and grease and to help combat odor-causing residue.
- If the washer door is left closed when not in use, the washer remains sealed, preventing the machine from fully drying out between cycles and increasing the potential for the development of odor-causing bacteria and mold.
