Low Water Flow

What it means

This code appears on Whirlpool washers built for North America, usually shown as Lo FL on the display, and means water is entering more slowly than expected. It is more a warning than a failure, and the machine may pause until the flow improves; the same number can mean something else on other brands. This meaning applies to Whirlpool models built for North America, such as Duet and Cabrio; Whirlpool washers sold elsewhere use different codes, so check your manual.

Models covered: Whirlpool washing machines sold in North America (e.g. Duet front-load, Cabrio top-load); Whirlpool models from other regions use different codes.
