What type of detergent must I use in the W11042232 washing machine?

You must use only High Efficiency (HE) detergents, which will be marked 'HE' or 'High Efficiency' on the package. Using non-HE detergent with this low-water washer creates excessive sudsing, which can result in longer cycle times, reduced rinsing performance, component malfunction, and over time, buildup of mold or mildew. Never exceed the Max line on the dispenser and always follow the detergent manufacturer's instructions for the correct amount to use. (Page 4)
