Mention the spill and its visible path, but do not assume there is a normal route between compartments. Cabinet designs and drainage arrangements differ.
What the observation tells you
Liquid may travel along an exterior edge or an accessible fitting, while ice inside the freezer may have another source. Pouring more water to reproduce the path can create damage. Fixed panels should remain in place during household observations.
A useful next step
Clean the spill using the approved method, protect food and record any recurring ice independently. An engineer can assess the relationship if the pattern continues.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
