Small valves and channels can be sheltered from ordinary spray, and some parts require a specific cleaning method. A dishwasher-safe bottle body does not establish that every assembled passage is cleaned.
Understanding this situation
Follow the product's instructions for removable components, brushes or other permitted care. Do not use an improvised basket arrangement that allows small pieces to fall into the appliance.
A useful next step
Place only approved components securely and reassemble as directed after checking them. If an item is lost, stop and inspect safely rather than running another cycle to recover it. The dishwasher is not a universal substitute for product-specific cleaning.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
