Maintenance Drum Pump Standard

If your LG Smart Tumble Dryer (especially a condenser or heat pump model) is not draining, the issue could be related to the Maintenance Drum Pump Standard (often referred to as the drain pump or condensate pump). Here’s how to locate and maintain it:

1. Where is the Drain Pump Located?

In most LG condenser/heat pump dryers, the drain pump is located at the bottom of the machine, behind the kickplate or lower access panel.

• Front-access models: Remove the small panel at the bottom front (may require a screwdriver).

• Rear-access models: You might need to tilt or lay the dryer on its back to access the pump.

(Note: Some models integrate the pump with the condenser unit.)

2. How to Check & Clean the Drain Pump

Tools Needed:

• Flathead screwdriver

• Towel or bowl (to catch water)

• Soft brush or cloth

Steps:

1. Unplug the dryer (safety first!).

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

3. Locate the pump – It’s a small, rectangular unit with a hose connected.

4. Check for blockages:

• Detach the drain hose and inspect for lint/debris.

• Remove the pump cover (if possible) and clean out any buildup.

5. Test the pump manually (if accessible, spin the impeller to check for jams).

6. Reassemble everything and run a test cycle.

3. Common Issues & Fixes

• Pump not working? → Could be a failed motor or clog.

• Still not draining? → Check the drain hose for kinks or blockages.

• Error codes (like OE or UE)? → May indicate a pump failure.

4. Preventative Maintenance

✔ Clean the lint filter after every use
✔ Check the drain pump every 3-6 months
✔ Ensure the drain hose is not bent or clogged
