LG washer code FF: frozen water lines

Fixable with care

Also shown as u51

What it means

The washer thinks water in the tub, drain hose or inlet hoses has frozen.

What to try

Unplug the washer before any step beyond a quick look, and turn the water off before touching hoses.

  1. Thaw the tub, drain hose and inlet hoses with warm water. LG gives about 122 to 140°F for the tub and below 122°F for the hoses.
  2. Run Rinse and Spin to test.

Call a technician if

  • FF appears in warm weather, when nothing could have frozen.

Resetting an LG washer

LG’s usual reset: unplug the washer for 10 to 60 seconds (LG gives different times for different codes), plug it back in and restart. If the code persists, contact LG for service.
