Plastic drum pumps with anti-drip nozzles

If your LG Smart Tumble Dryer has a plastic drum pump with anti-drip nozzles, it's likely part of the condensate drainage system in a condenser or heat pump dryer. These pumps are designed to remove water efficiently while preventing leaks. Here’s how to locate, maintain, and troubleshoot them:


1. Identifying the Plastic Drum Pump with Anti-Drip Nozzles

  • Purpose: Moves condensed water from the drum to the drain tank or external hose.

  • Anti-drip feature: Prevents residual water from leaking when the pump is off.

  • Common in:

    • LG Heat Pump Dryers (e.g., LG RC90V** series)

    • LG Vented Condenser Dryers (e.g., LG DLEX** series)


2. Where is the Pump Located?

  • Behind the bottom front panel (most common) – Remove the kickplate to access.

  • Near the condenser unit – Some models require removing the condenser first.

  • Attached to the drain hose – Follow the hose from the drum to locate the pump.

(Check your user manual for the exact location based on your model.)


3. How to Clean & Maintain the Pump

What You’ll Need:

  • Screwdriver (for panel removal)

  • Bowl/towel (to catch water)

  • Pipe cleaner or soft brush

Steps:

  1. Unplug the dryer (safety first!).

  2. Remove the lower front panel (or rear panel if needed).

  3. Locate the pump – Look for a small plastic box with hoses attached.

  4. Check the anti-drip nozzle:

    • Gently detach the hoses and inspect for clogs.

    • Clean the nozzle with warm water and a brush (avoid sharp tools).

  5. Test the pump impeller:

    • Manually spin the impeller (if accessible) to check for jams.

  6. Reassemble and run a test cycle.


4. Common Issues & Fixes

5. Preventative Tips

  • ✅ Monthly cleaning – Flush the pump with warm water.

  • ✅ Check hoses – Ensure no kinks or blockages.

  • ✅ Use distilled vinegar (occasionally) to prevent limescale buildup.


6. Replacement Considerations

If the pump is damaged:

  • Part number: Typically starts with LG 383ER... (varies by model).

  • DIY replacement: Disconnect hoses, unclip the pump, and install the new one.
