Electrolux ELFW7637AT 4.3 cu ft Front Load Washer with SmartBoost and Steam Cleaning Technology EF2 Error Fix: Excessive Suds Detected

The pressure sensor has detected excessive suds (foam) in the drum. Too much detergent or the wrong type of detergent was used. Electrolux front-load washers require HE (High Efficiency) detergent only. Using regular detergent creates too many suds which interfere with washing, rinsing, and draining. The washer will attempt to rinse away the suds with additional rinse cycles. Use only HE detergent and follow the recommended amount on the detergent package. Use less detergent for soft water areas. Run an empty hot wash cycle with no detergent to clear residual suds.
