No. Moving debris into an unseen passage is not the same as removing it. Hidden areas may contain sharp fragments or components unsuitable for owner access.
Understanding this situation
The model's routine filter-cleaning instructions define what can be handled safely. A generic video showing a different pump arrangement should not be used as authority to reach deeper.
A useful next step
Collect accessible material only through the permitted procedure while safe. If the blockage is beyond that boundary, seek service advice. Do not pour drain chemicals into the opening or run repeated cycles to force debris onward.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
