Do not pour boiling water onto the liner or into openings. Sudden heat and uncontrolled water can damage materials or reach unsuitable areas.
What the observation tells you
Some manuals permit a carefully placed container of warm water during a specific procedure; that is not the same as pouring boiling water over the cabinet. The exact method and temperature matter. Do not transfer instructions between models without checking applicability.
A useful next step
Protect the food and follow the prescribed process. Collect meltwater as directed and keep electrical parts dry. If the approved method is unclear, wait for guidance rather than escalating heat or force.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
