LG washing machine making intermittent noise — video link included

From your description, the **drain pump is a strong suspect**, especially as the noise seems to come from the **bottom right front** and appears only when a pump is running. On many LG washers that’s where the pump/filter area is. It could also be a loose mounting, debris in the pump, or less commonly the inlet valve buzzing when filling.

1. **Pin down exactly when the noise happens** Try a **drain/spin only** cycle and then a **fill/rinse** stage if possible. - If it happens when **emptying water**, suspect the **drain pump**. - If it happens when **taking water in**, the **inlet valve** may be buzzing or vibrating.

2. **Check the pump filter** **Isolate from the mains first** before inspecting anything internal. Open the little flap at the lower front and check/clean the **pump filter**. Look for coins, hair grips, bra wires, buttons, or lint. Even a small object can cause an intermittent rattling/grinding noise.

3. **Listen for vibration from the pump housing** If the filter is clear, the pump itself may have **worn bearings/impeller play** or a **loose fixing**, which can cause a buzzing/rattling noise but still allow it to pump normally.

4. **Check for foreign objects in the sump hose** Sometimes debris sits in the hose between tub and pump and only moves into contact when draining.

5. **Age-related point** At 15 years old, a pump can become noisy before it fails completely. If the machine otherwise works normally, this may be an early warning rather than an immediate breakdown.

If you confirm whether the noise is only on **drain** or also on **fill**, that would narrow it down a lot. For any internal electrical checks, or if the pump needs replacing, it’s best to use a qualified appliance engineer. Also, any mains, gas, or sealed refrigeration work should be left to a qualified engineer.

Note that it does not make the noise when it is pumping water out.
