Tools You Will Need
To test your LG washing machine drain pump, you’ll need a few tools.

- Bucket
Steps to Test Your LG Washing Machine Drain Pump
Step 1: Disconnect Power and Water Supply
Safety should always be your first concern. Turn off and unplug your washing machine, and disconnect the water supply.
Step 2: Locate the Drain Pump
Usually, the drain pump is located at the bottom of the machine. Refer to your LG washing machine’s manual to be certain.
Step 3: Access the Pump
Use your screwdriver to remove any screws securing the access panel. Be prepared with towels or a bucket to catch any water that may spill.
Step 4: Identify and Disconnect Wires
The drain pump is usually connected by two or more wires. Take note of their placement before disconnecting them.
Step 5: Use a Multimeter
Set your multimeter to the ohms setting. A functional pump should read between 20 and 30 ohms. If the reading is zero or infinite, the pump is likely faulty.
| Multimeter Reading | Condition of Drain Pump |
|---|---|
| 20-30 ohms | Likely Functional |
| Zero or Infinite | Likely Faulty |
Step 6: Physical Inspection
Also, look for any visible signs of wear or damage like cracks or burns. If you spot any, you’ll probably need to replace the pump.
Step 7: Reassemble and Test
After the tests, reconnect everything and run a drain cycle to check if the problem persists.
When to Call a Professional
- Complex electrical issues
- Structural damage to the pump
- Inability to determine the issue even after testing
If you find yourself in any of these situations, it’s probably best to consult a professional for an expert diagnosis and repair.
