No. Owner-accessible clearing points and approved tools are model-specific, and some appliances do not provide the same arrangement. Do not insert a tool into an unidentified hole or apply force based on a video of another model.
What the observation tells you
The presence of a supplied key does not replace the full safety and isolation instructions. It also does not establish that a particular stoppage is a mechanical jam. A leak, electrical trip or burning smell changes the next step.
A useful next step
Check the full model manual. If it does not explicitly support the proposed owner procedure, leave clearing and diagnosis to an engineer.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
