This demonstration guide answers one field question about inlet water above the pump’s documented temperature. Measurements come before parts, and the notes are not a generic equipment FAQ.
Diagnose before replacing parts
Start with inlet temperature at the garden-hose connection. That reading separates inlet water above the pump’s documented temperature from adjacent faults that share the same complaint.
If the measurement is out of spec, treat the packings as the primary path. If it is in spec, do not replace the packings just to complete a parts list.
Repair the failed system
The usual correction is the packings, installed to the documented spec for this complaint.
A demonstration shop records the finding so the next technician is not repeating a guess about inlet water above the pump’s documented temperature.
Stop before you make it worse
Do not feeding the pump from a hot-water tap to "clean better". That shortcut hides the original measurement and creates a second failure.
If the machine still fails after the packings is corrected, convert the visit to a broader diagnosis rather than stacking parts.
