Typical Failure Modes
Compiled for this model from its own documentation and established engineering knowledge for this equipment class - not from a verified service record. Confirm against the manufacturer's service manual.
Fluid-volume reading inaccurate
HighSymptoms: Dial or graduation reading disagrees with the actual collected / metered volume.
Root cause: Worn or stuck metering mechanism, a float / sensor fault, or air trapped in the chamber.
Will not hold vacuum / leak
MediumSymptoms: Suction not maintained, hiss at the lid or connectors, chamber will not fill.
Root cause: Worn lid gasket, tubing, or quick-connect couplings.
Chamber / valve blockage
MediumSymptoms: Fluid not flowing through, metering stalls.
Root cause: Debris or clot in the inlet / chamber, or a stuck valve.
Overflow / carry-over into the vacuum line
MediumSymptoms: Fluid reaches the vacuum source or filter.
Root cause: Float shut-off or hydrophobic filter fault.

Troubleshooting Approach
A starting sequence for this model, compiled from its documentation and engineering knowledge for this equipment class. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Volume reading looks wrong
- Meter a known volume of fluid and compare to the dial / graduations.
- Clear any trapped air from the chamber.
- Inspect the metering mechanism / float for sticking or wear.
- Replace the metering assembly if it is inaccurate.
- Re-verify with a known volume.
Symptom: Will not hold vacuum
- Inflate / apply vacuum and watch for a steady loss.
- Inspect the lid gasket, tubing and connectors for leaks.
- Replace the leaking part.
- Confirm the float shut-off and overflow filter are intact.
- Re-test vacuum hold.
