What type of detergent should I use in this washer?

Use only High Efficiency (HE) detergents marked with 'HE' or 'High Efficiency' on the package. Regular non-HE detergent will create too much sudsing and can result in washer errors, longer cycle times, reduced rinsing performance, and potential component failures. Follow the manufacturer's instructions for the correct amount to use, remembering that concentrated detergents like 2x will require less product. (Page 11)
