First check visible food containers and packaging without assuming the liquid comes from the appliance. A spilled drink or raw-food package requires a different response from clear recurring condensation.
What the observation tells you
Colour and smell are clues, not a safe chemical identification method. Avoid touching an unexplained substance unnecessarily or tasting it. If there is a strong chemical odour, damage or cooling failure, stop the investigation and obtain advice.
A useful next step
Protect unaffected food, follow suitable hygiene and appliance-cleaning instructions, and note the liquid's location. A photograph taken safely before cleaning can help distinguish a local spill from a recurring water path.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
