Liquids can expand during freezing, so use a suitable container and the headspace recommended for that food and container. Filling to the brim can damage a lid or vessel.
What the observation tells you
A leak may freeze around a drawer and later look like water entering from the appliance. Rigid glass needs particular care: being reusable for cupboard storage does not establish freezer suitability. Do not force a distorted lid shut after freezing.
A useful next step
Use freezer-rated packaging, keep it upright where required and leave room without blocking vents. If a container breaks, protect yourself and other food from fragments and follow safe cleanup rather than chipping it free.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
