LG F1406 washing machine noisy on rinse with occasional small leak

The problem

An LG Steam washing machine, model F1406 TDSP/F1406, around 10 years old, was reported to make a very loud rattling noise during the rinse cycle, described as like a few bouncy balls inside the drum. A small amount of water also leaked out occasionally. When the drum was spun by hand while empty, the noise was not present, and the user did not feel excessive side-to-side movement from the top.

Likely cause

The strongest diagnosis in the discussion was that something was loose, most likely the motor or a drum weight. The leak was mentioned by the user but no confirmed cause for the leak was identified in the thread.

What fixed it

Recommended action was to disconnect the appliance from the mains, remove the lid and back panel, and listen/observe to locate the source of the noise, then physically check for loose components by shaking accessible parts. The exact repair was not confirmed in the discussion.
