No. Panels may conceal electrical equipment, pipework or other services. Use records and known safe owner-access points first.
What the observation means
A sound behind a wall does not prove which panel gives access. Removing finishes can create damage without identifying the correct unit.
A useful next step
Tell the service team what is known and what remains uncertain. Provide an existing floor plan or installation record if available. Do not drill exploratory holes, reach into concealed spaces or operate extra fixtures to trace the pump by noise.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
