The openings and access arrangements can differ, and one compartment may have no owner-serviceable drain. A method suitable for one visible channel is not a universal procedure.
What the observation tells you
Pushing a tool into a freezer outlet may damage a duct or concealed part. Pouring liquid into it can create additional ice or electrical risk. Familiarity with another model does not identify the opening safely.
A useful next step
Use only the locations and methods described for the exact appliance. If water or ice persists outside those owner-care provisions, report the pattern and arrange assessment.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
