Manufacturers sometimes cover several versions in one manual. Optional features and illustrations need to be matched to the actual model and installed fittings.
What the observation tells you
A missing control is not automatically evidence that a component has been removed. Searching for an illustrated drain, filter or button on the wrong variant can lead to unnecessary dismantling. Notes such as 'depending on model' matter when interpreting the instructions.
A useful next step
Check the full reference and the applicable diagram before following a procedure. Ask the manufacturer if the variant remains unclear. Use only functions and user-accessible fittings that genuinely exist on the appliance.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
