High Efficiency (washing machines)

"High Efficiency", or "HE" for short, is a term now being used by the Soap and Detergent Association. The term refers both to newer washing machines, which apparently use components more sensitive to damage by detergent suds, and to detergents (and possibly non-detergent soaps, though their site seems to avoid admitting that one can use anything but detergent for doing laundry in a washing machine) which are suitable for use with those machines.

Machines labeled using the "HE" logo often require the use of HE-compliant detergents; the use of non-compliant detergents voids the warranty.
