Do not use steam cleaning unless the exact manufacturer instructions explicitly permit the task. Moisture and pressure can reach electrical or delicate components through openings.
Understanding this situation
A laundry appliance's ability to process damp clothes does not make its control panel or cabinet suitable for external steam injection. Internal cleaning and ordinary programme moisture follow different designed routes.
A useful next step
Use the stated owner-care method for each accessible part. If contamination cannot be removed that way, obtain advice. Do not steam the drum, vents or controls to disinfect a machine that has an unresolved smell or drying fault.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
