What the symptom can mean
A sound following the drum can indicate contact or a rotating component, while cabinet resonance can imitate it. Inspection is needed before selecting a replacement part.
Place the sound in use
Say whether it occurred from the beginning, started only after warming or continued after tumbling stopped. Include the load and whether the cabinet itself vibrated against anything nearby.
Keep the result too
A noise with normal drying performance differs from a noise followed by a stop or warning. Mention either outcome and leave covers and the fitted position undisturbed for assessment.
