Use the capsule exactly where its maker and the appliance instructions permit. A product designed to dissolve among the laundry should not be assumed suitable for a drawer passage or an automatic-dosing reservoir.
Understanding this situation
Drawer compartments deliver products at particular stages and through restricted routes. A capsule, powder or thick gel placed in the wrong section can behave differently from the product for which it was intended. Opening or puncturing a capsule to make it fit also creates unnecessary exposure to concentrated detergent.
A useful next step
Check both sets of instructions before the next wash. If the wrong product has already been used, stop adding further detergent and seek the specified cleaning guidance once the machine is safe and cool. Keep laundry products away from children, and treat any exposure or ingestion as a separate urgent matter requiring appropriate professional advice.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
