Paul Berry, owner of Diamond Certified company Martin and Harris Appliances, says manufacturers are warning consumers about the importance of using the right laundry detergent with new, high efficiency (HE) front- and top-loading washing machines. If you don’t, says Mr. Berry, you might create too much sudsing and cause longer cycle times, poor rinsing, noticeable mold or mildew, and even component failures.
HE machines require HE detergents, preferably liquid ones. Manufacturers recommend against using some brands of dry HE products, which contain chemicals that can damage spindles and rear bearings. You also need to use less detergent and fabric softener, because HE systems use 65 percent less water. When you add too much, your clothes will have stains and/or a waxy build-up on them. Usually, you only need about one tablespoon of detergent or softener for a full load of laundry.
