What type of detergent should I use in this washing machine?

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, and potential component failures. HE detergents are formulated to produce the right amount of suds for optimal performance.
