It records what was actually found and changed, which is stronger evidence than remembering that the pump was serviced.
What the observation means
A recurring sound may have a different cause or arise in another part of the installation. The normal period between repairs is relevant.
A useful next step
Provide the report, dates and current symptoms separately. Do not open the unit to verify an old part number yourself. Let the previous provider review any applicable follow-up arrangement, while stopping fixture use for leaks, poor clearance or electrical warning signs.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
