Washer-dryer combo will not drain; cycle stops with water remaining in drum and OE displayed.

Safety first: Unplug the LG washer-dryer combo and turn off the water supply before working on it. Water may spill when opening the filter—have towels and a shallow pan ready.

• 1. Check for a simple drain hose issue:
  • Ensure the drain hose is not kinked or crushed behind the unit.
  • Verify the hose is not inserted too far into the standpipe (should be about 6–8 inches) and that the standpipe is not clogged.
• 2. Clean the drain pump filter:
  • Locate the small access door at the bottom front of the machine.
  • Place a shallow pan and towels under the door.
  • Open the access door and slowly loosen the drain cap or small drain tube (if equipped) to let water out.
  • Remove the drain pump filter and clean out lint, coins, buttons, and debris.
  • Inspect the impeller inside the pump housing for damage or obstruction; it should spin freely.
  • Reinstall the filter securely.
• 3. Run a drain/spin test:
  • Plug the unit back in and run a Drain+Spin cycle with no clothes.
  • If OE returns and water does not pump out, the drain pump motor is likely faulty.
• 4. Inspect/replace the drain pump:
  • Unplug the unit again.
  • Remove the lower front panel or rear panel (model dependent).
  • Locate the LG drain pump assembly (usually mounted at the front bottom with hoses attached).
  • Check wiring connections for burns or looseness.
  • If the pump hums but does not move water, or is silent and getting power, replace the drain pump assembly.
• When to call a technician: If you are not comfortable removing panels or working around water and electrical connections, contact a qualified appliance technician.
