What This Guide Helps With
Troubleshooting waste, drain, fluid container, tubing, or liquid handling errors that may interrupt CLINITEK Novus urine analyzer operation.
Step-by-Step Troubleshooting
Ensure Patient Safety First
Confirm the CLINITEK Novus is not actively processing a patient specimen before troubleshooting the waste or fluid handling system.
If patient testing is needed immediately, have laboratory staff use another validated analyzer or follow approved downtime procedures.
Expected outcome: Patient testing is not delayed or reported from an analyzer with unresolved fluid handling concerns.
Verify the Reported Error
Ask staff what message or behavior was observed.
Check whether the issue involves:
- Waste container full
- Waste bottle not detected
- Fluid handling error
- Drain or waste line blockage
- Overflow warning
- Leaking fluid
- Analyzer stopping during sample processing
- Repeated waste-related alarms after emptying the container
Expected outcome: The failure is confirmed as a waste or fluid handling issue, not a general analyzer, power, strip, or LIS problem.
Remove the Analyzer From Active Testing
Pause additional patient testing until the waste or fluid issue is understood.
Confirm with the lab whether any specimens were interrupted and need repeat testing per laboratory policy.
Expected outcome: No questionable or incomplete patient results are released.
Check the Waste Container Level
Inspect the waste container and verify whether it is full or near full.
Empty the waste container according to facility biohazard and laboratory procedures.
Reinstall the container securely.
Expected outcome: A full-waste condition clears after the container is emptied and properly reinstalled.
If this resolves the issue, stop troubleshooting and return the analyzer to service after staff confirm normal operation.
Verify Waste Container Seating
Confirm the waste container is fully seated in its proper position.
Check that the cap, lid, fittings, or sensor contact points are aligned correctly.
Expected outcome: The analyzer recognizes the waste container and no longer reports a missing or improperly seated container.
Inspect for External Leaks
Look around the analyzer, waste container, tubing path, and nearby bench area for visible liquid.
Do not continue testing if fluid is leaking from the analyzer or collecting under the unit.
Expected outcome: No active leakage is present.
If leakage is present, remove the device from service and escalate for repair.
Check Waste Tubing for Kinks or Pinching
Inspect accessible external tubing connected to the waste container.
Look for:
- Kinked tubing
- Pinched tubing
- Tubing trapped behind the analyzer
- Loose tubing connections
- Tubing routed uphill or under strain
Correct any obvious routing issue without forcing fittings.
Expected outcome: Waste tubing is connected, unobstructed, and routed normally.
Confirm the Waste Container Is Not Overfilled After Emptying
After emptying, make sure the container is actually drained and not partially blocked by residue, foam, or debris.
Reattach it and verify the analyzer’s waste status.
Expected outcome: The analyzer shows the waste container as ready or no longer full.
Check for Dried Residue or Crystallized Waste at Accessible Fittings
Inspect user-accessible waste bottle fittings and caps for dried urine residue, crystallization, or buildup.
Clean only exterior-accessible areas using approved lab cleaning procedures and PPE.
Do not insert tools into internal ports or disassemble internal fluidics.
Expected outcome: Accessible fittings are clean enough to allow normal seating and waste flow.
Verify Reagent, Rinse, or Wash Containers if Applicable
Some fluid handling errors may involve more than waste alone.
Check that required reagent, rinse, or wash containers are present, not empty, correctly installed, and not expired if applicable.
Expected outcome: All external fluid containers required for operation are installed and ready.
Power Cycle Only When Safe
If the waste container has been emptied, tubing is clear, and no leak is present, restart the analyzer according to normal site practice.
Allow the analyzer to complete startup or self-check.
Expected outcome: The fluid handling or waste error clears after the analyzer rechecks container status.
Run a Non-Patient Verification Workflow
Have laboratory staff perform the appropriate QC, maintenance check, or non-patient verification process before returning the analyzer to patient testing.
Expected outcome: The analyzer operates without repeating the waste or fluid handling error.
Watch for Repeated Errors
If the same waste or fluid handling error returns after the container is emptied, tubing is corrected, and the analyzer restarts, suspect an internal sensor, pump, valve, tubing, or fluidics issue.
Expected outcome: Repeated errors are recognized as requiring bench evaluation or vendor repair, not continued front-line troubleshooting.
If the Problem Persists
If the waste container is empty, correctly seated, tubing is not kinked, there are no external leaks, and the error still returns, common external causes have been ruled out.
The CLINITEK Novus should be:
- Removed from service
- Labeled Out of Service
- Sent for repair, bench evaluation, or vendor service support
Repeated waste or fluid handling errors may involve internal fluidics, sensors, pumps, valves, or tubing that should not be handled through basic troubleshooting. Knowing when to stop is proper troubleshooting.
Clinical Use Tip
Do not troubleshoot waste or fluid handling errors while active patient specimens are being processed. Urine waste should be treated as biohazard material, and PPE should be used when handling containers, tubing, or suspected leaks. If testing is urgent, move the workload to another validated analyzer first.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Laboratory staff reported the CLINITEK Novus displayed a waste/fluid handling error and stopped processing urine specimens."
Cause
What was observed during troubleshooting.
Example:
"Waste container was found nearly full and not fully seated after being emptied by staff."
Resolution
What action was taken.
Example:
"Emptied and reseated the waste container, verified external tubing was not kinked, restarted the analyzer, and had lab staff complete QC successfully before returning the unit to service."
Helpful Details to Include (If Known)
- Exact waste or fluid handling error message
- Whether the waste container was full
- Whether the waste container was reseated
- Whether tubing was kinked, pinched, loose, or blocked
- Any visible leaks around the analyzer or waste bottle
- Whether reagent, rinse, or wash containers were checked
- Whether the error cleared after restart
- QC or verification result after troubleshooting
- Alarm behavior
- Accessories swapped
- Power behavior
- Environmental factors
- Indicator lights
- Final device status
- Whether repair or vendor service was required
Final Thought
Waste and fluid handling issues should be approached carefully because they affect both analyzer reliability and biohazard safety. Start with the simple external causes first: container level, seating, tubing, leaks, and accessible fittings. If the error repeats after these checks, remove the analyzer from service and document the findings clearly using CCR.
That is successful troubleshooting.
