This washer is designed for use with only HE (High-Efficiency) detergents.

HE detergents produce fewer suds, dissolve more efficiently to improve washing and rinsing performance, and help to keep the interior of the washer clean. Using detergent that is not HE may cause oversudsing and unsatisfactory performance which could result in error codes, cycle failure, and washer damage.
This machine requires very little detergent. For proper wash performance, always use the dispenser and measuring device provided with the machine.
The manual dispenser holds a maximum of 2 teaspoons (10 g / 10 cc) of HE detergent. Most normal loads require only 1 teaspoon (5 g / 5 cc) of detergent, or filling the dispenser to the halfway line.

Max load: 2 teaspoons (10 g / 10 cc)
Normal loads: 1 teaspoon (5 g / 5 cc)
For proper wash performance, always measure detergent using the measuring device provided. For an average load, use half of the recommended maximum. Use less detergent for soft water, light soil, or smaller loads.
Never use more than the maximum amount of detergent recommended. Using too much detergent can lead to oversudsing, poor rinsing, detergent buildup in clothing, and residue buildup that can contribute to odors in the washer.
Use extra care when measuring 2X and 3X concentrated detergents because even a small amount of extra detergent can lead to problems.
Detergents designated as HE-compatible may not provide optimal results.
