Do not push improvised wire into an appliance opening. Use only the owner-cleaning method and tool specified for the identified drain on your exact model.
What the observation tells you
A concealed channel may change direction or sit close to components that should not be probed. A rigid wire can push debris deeper, damage material or enter the wrong opening. An online photograph of a similar fridge is not enough to establish a safe route.
A useful next step
Check the manual and clean only the accessible part it describes. If that does not restore normal drainage, stop extending the procedure. Record whether water returns after ordinary use so an engineer can assess the underlying restriction safely.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
