Residual water can refreeze when the appliance restarts and recreate sticking or local ice. Drying the permitted accessible surfaces is part of completing the process.
What the observation tells you
Water trapped under a removable fitting may be missed even when the main liner looks dry. Do not dismantle fixed components to chase moisture. Check that any owner-operated drain plug and baskets are refitted as instructed before loading.
A useful next step
Follow the startup guidance and confirm suitable storage conditions. If ice returns quickly despite correct completion, record its location and timing instead of repeating defrosting indefinitely without assessing the cause.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
