LG WM3400CW Washer Not Draining Fix
An LG WM3400CW washer that will not drain often points to a blocked filter, a kinked hose, or a worn drain pump. Because this model depends on full drainage before strong spin begins, fixing the drain issue often restores better spin performance too.
Common Symptoms
- Water is left in the drum after the cycle
- The machine pauses at drain or spin
- The pump hums but little water moves out
- Drain-related warnings appear repeatedly
