An excessive or spilled product can affect the result, so more is not automatically better. Use the dispenser's limit and the model's adjustment instructions.
Understanding this situation
Streaks, foam or other changes need to be described rather than assigned to one cause by appearance alone. A dose setting and an accidental spill into the tub are also different events.
A useful next step
Measure carefully and deal with spills as instructed. Make only supported adjustments and observe ordinary safe results. If excessive foam or leakage occurs, stop and obtain guidance rather than adding another cleaner or repeatedly restarting the same cycle.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
