What type of detergent must I use with the W10873891 washing machine?

You must use only High Efficiency (HE) detergents, marked 'HE' or 'High Efficiency' on the package. Using regular non-HE detergent with this low-water washer creates excessive sudsing, which will likely result in longer cycle times, reduced rinsing performance, component failures, and noticeable mold or mildew. The Load & Go™ dispenser only supports liquid HE detergent, not powder. (Page 4)
