Whirlpool Dryer LF — What It Means & How to Fix It
LF on a Whirlpool HybridCare dryer means the lint filter has been removed — put the HybridCare filter back in and make sure its handle is properly seated.
What this code means
Whirlpool says an LF (Lint Filter) code indicates that the HybridCare filter has been removed. The remedy is to place the filter into the dryer with the handle properly seated.
