Washer-dryer combo drum turns but makes a rhythmic thumping noise, especially with light loads.

Safety first: Unplug the unit before reaching inside the drum to check for loose parts.

Step-by-step checks:

• 1. Inspect drum interior: Rotate the drum slowly by hand and listen for clicking or thumping. Check each baffle for looseness or cracks.
• 2. Check for foreign objects: Look for coins, buttons, or other items stuck in the drum holes or under the baffles.
• 3. Tighten or replace baffles: If a baffle is loose, access its mounting screws from inside the drum or from the outer tub (depending on design). Tighten or replace with an OEM Monogram drum baffle.
• 4. Verify leveling and feet: Ensure the unit is level and all feet are firmly on the floor to minimize resonance.

When to call a technician: If the noise persists and no obvious cause is found, internal drum or tub issues may require professional inspection.
