What type of detergent should I use in my Wfw9250Ww 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, result in washer errors, longer cycle times, reduced rinsing performance, and may cause component failures and mold or mildew. HE detergents are made to produce the right amount of suds for best performance.
