Different deposits require different permitted care approaches. A product intended for mineral deposits is not automatically the right answer to grease or trapped food.
Understanding this situation
Identify what is visible and review the model's cleaning instructions. The smell of the machine or the broad local water description alone does not specify a universal chemical treatment.
A useful next step
Choose an approved product for the actual maintenance task and use it as directed. Do not mix cleaners or repeat them aggressively. If ordinary care does not resolve a programme fault or poor results, provide the symptoms for assessment.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
