Laundry should not obstruct the appliance's documented ventilation or safe access. A basket, folded towels or hanging fabric can cover areas that need to remain clear.
Understanding this situation
The exact clearances depend on the model and fitting. Soft items should not be used to muffle an unfamiliar sound, and storage should never block the ability to isolate the appliance safely.
A useful next step
Keep the surrounding area arranged according to the instructions. If unusual heat or smell develops, stop use and report it rather than merely moving the basket and assuming the cause is resolved. Avoid reaching behind an operating machine.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
