Washer-dryer makes a clicking or knocking noise during drum rotation at low speed.

Safety first: Unplug the appliance before reaching into the drum or removing parts.

Step-by-step checks:

• Inspect drum paddles: Check plastic lifters inside the drum for looseness. Tighten or replace if they move.
• Look for objects: Rotate the drum slowly and listen for rattling. Use a torch to look through drum holes for trapped items.
• Access foreign objects: Some Proline models allow removal of a drum paddle to retrieve objects from between drum and tub. Follow service instructions to unclip and remove the paddle, then remove the object.

When to call a technician: If the object cannot be accessed through the drum or heater opening, the tub may need partial disassembly by a professional.
