What This Guide Helps With
Use this guide for fluid-related faults involving accessible waste, fluid containers, leaks, tubing connections, or other external fluid-management conditions.
Step-by-Step Troubleshooting
1. Protect Staff, Specimens, and Equipment
Stop patient testing if a fluidics fault could affect specimen processing or if leakage is present.
Use appropriate laboratory precautions for any biological or chemical material. Do not handle unknown leakage without required PPE and laboratory safety procedures.
Expected outcome: Staff and patient testing are protected before equipment troubleshooting begins.
2. Confirm the Exact Fault
Determine whether the problem involves:
- Waste status
- Fluid supply status
- Leak indication
- Repeated fluid-handling fault
- Drainage problem
- A general fluidics message
Record the exact message and when it occurs.
Expected outcome: The failure is narrowed to a specific fluid-management function.
3. Inspect Accessible Fluid and Waste Containers
If the system uses externally accessible containers in the affected workflow, verify they are:
- Present
- Correctly installed
- Properly seated
- Not visibly damaged
- Not leaking
- At an appropriate physical condition for operation according to laboratory procedure
Do not overfill or manually defeat level-detection systems.
Expected outcome: External fluid and waste containers are correctly installed and physically intact.
4. Inspect External Tubing and Connections
Inspect accessible fluid lines and connectors for:
- Kinks
- Pinching
- Disconnection
- Leakage
- Cracks
- Compression by nearby equipment
- Incorrect routing
Do not remove internal tubing or open protected fluid circuits.
Expected outcome: External fluid paths are connected and unobstructed.
5. Check for Leaks or Spills
Inspect around and beneath the analyzer for moisture, dried residue, or active leakage.
If an active leak appears to originate inside the equipment, stop troubleshooting, disconnect power when safe, and remove the system from service.
Expected outcome: No uncontrolled leak or contamination hazard is present.
6. Verify Waste Routing
Where external waste routing is used, verify the line is not elevated, kinked, blocked, compressed, or improperly positioned relative to the approved installation.
Do not alter facility drains or plumbing without coordination with the appropriate department.
Expected outcome: External waste routing permits normal drainage.
7. Verify Normal System State
Confirm the analyzer completed initialization and that the fluidics fault is not secondary to another startup, positioning, or sensor problem.
If a normal operator-accessible reset or recovery step is available to trained personnel, it may be performed once after an obvious external cause is corrected.
Expected outcome: The system recognizes normal fluid and waste conditions.
8. Observe One Controlled Functional Test
After correcting an external condition, perform an appropriate approved functional check.
Watch for:
- Repeat leak
- Fluidics message
- Abnormal sound
- Failure to clear waste
- New alarms
Expected outcome: The fluidics system completes normal operation without recurrence.
If the fault clears and verification is successful, troubleshooting can stop.
9. Perform Final Functional Verification
Verify the analyzer remains dry, no abnormal fluidics messages recur, containers and tubing remain properly positioned, and laboratory-required verification is completed.
Expected outcome: Fluid handling is stable and suitable for return to use.
If the Problem Persists
If external containers, tubing, waste routing, leakage, system state, and accessible connections have been verified, common external causes have been ruled out.
The remaining problem may involve an internal pump, valve, tubing path, leak sensor, level sensor, fluid-control mechanism, or other service-level condition.
The device should be:
- Removed from service
- Labeled Out of Service
- Sent for repair or bench evaluation
- Evaluated using appropriate manufacturer documentation and approved test equipment
- Repaired or configured only by qualified personnel
Do not bypass leak detection, level sensing, or internal fluid controls. Knowing when to stop external troubleshooting is proper troubleshooting.
Complete leak checks, functional testing, and applicable laboratory verification before return to service.
Clinical Use Tip
Any unexplained internal leak or recurring fluidics fault warrants removal from service because contamination and unreliable sample processing may occur together.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Laboratory staff reported a recurring waste-related fault on the bioMerieux VITEK 2 Compact."
Cause
What was observed during troubleshooting.
Example:
"Clinical Engineering found the accessible external waste line kinked behind the analyzer."
Resolution
What action was taken.
Example:
"Corrected the external waste-line routing, verified there was no leakage, completed a functional check without recurrence, and returned the system for laboratory verification."
Helpful Details to Include (If Known)
- Exact fluidics or waste message
- Fluid or waste container condition
- External tubing condition
- Leak location if present
- Waste-line routing
- Recent cleaning or maintenance
- Whether the analyzer was moved
- Abnormal sounds
- Fault behavior after correction
- Final leak check
- Final analyzer status
Final Thought
Start with visible containers, tubing, routing, and leaks before assuming an internal fluidics failure. Remove the analyzer from service when leakage or repeated faults cannot be safely resolved externally.
That is successful troubleshooting.
