Hello! For model WFW5720RR: CHOOSING THE RIGHT DETERGENT Use only High Efficiency detergents. The package will be marked “HE” or “High Efficiency.” Low-water washing creates excessive sudsing with a non-HE detergent. Using non-HE detergent will likely result in longer cycle times and reduced rinsing performance. It may also result in component failure and, over time, buildup of mold or mildew. HE detergents should be low-sudsing and quick-dispersing to produce the right amount of suds for the best performance. They should hold soil in suspension so it is not redeposited onto clean clothes. Not all detergents labeled as High Efficiency are identical in formulation and their ability to reduce suds. For example, natural, organic, or homemade HE detergents may generate a high level of suds. If you use one of these and see a message about excessive sudsing error code appear in the display, consider using a different HE detergent. Always follow the detergent manufacturer’s instructions to determine the amount of detergent to use. Do not go over the Max line on the dispenser.
