Explain whether the interruption occurred during washing, spinning, drying or cooling, and whether water or heat may remain. Those details affect safe recovery.
Understanding this situation
A blank display or still drum does not establish that the door can be forced. Do not use a generic emergency-release method from another machine, particularly after heating or when water is visible.
A useful next step
Leave the appliance in a safe condition and contact the service team with the model and last display. Avoid repeated restarts if the interruption involved tripping, burning or leakage. Existing observations can guide the appropriate next step.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
