What This Guide Helps With
Channel detection errors, failure to recognize connected scope channels, or inconsistent flushing due to connection or setup issues.
Step-by-Step Troubleshooting
Ensure Patient Safety First
- Do not troubleshoot while the scope is intended for patient use
- Remove the scope from service and use an alternate device if needed
- Ensure no patient care is impacted during troubleshooting
Expected: No risk to patient care during troubleshooting
Why it matters: Prevents use of improperly flushed or non-functional equipment
Verify the Reported Error and Behavior
- Power on the unit
- Observe for channel detection errors or missing channel indicators
- Note if issue occurs immediately or after connection
Expected: Error is reproducible or clearly displayed
Why it matters: Confirms a true detection issue vs user setup error
Check Channel Tubing Connections (Most Common Cause)
- Disconnect all channel tubing
- Reconnect each line firmly to the correct port
- Ensure proper port-to-channel matching
Expected: Channels are recognized after reconnecting
Why it matters: The system relies on proper pressure and flow paths to detect channels
Inspect Channel Adapters and Fittings
- Inspect O-rings, connectors, and fittings for wear or cracks
- Replace any visibly damaged adapters
- Ensure correct adapters are used for the scope type
Expected: Secure, airtight connections
Why it matters: Leaks or poor seals prevent proper pressure sensing
Verify Scope Compatibility and Setup
- Confirm correct scope model is being used with appropriate adapters
- Ensure all required channels are connected
- Verify no unused ports are left open if required to be capped
Expected: System recognizes all connected channels
Why it matters: Incorrect configuration can mimic detection failure
Check for Blockages or Kinks in Tubing
- Inspect tubing for kinks or bends
- Flush tubing manually if possible
- Replace tubing if blockage is suspected
Expected: Free flow through all lines
Why it matters: Flow restriction can prevent the system from sensing channels properly
Perform a System Reset (Power Cycle)
- Turn off the unit
- Disconnect power for 10–15 seconds
- Power back on and reconnect channels
Expected: System resets and may properly detect channels
Why it matters: Clears temporary sensor or control errors
Test with a Known-Good Scope or Setup
- Connect a different scope or verified working setup
- Observe if channels are detected correctly
Expected: Proper detection with known-good equipment
Why it matters: Helps isolate whether issue is with the unit or accessories
If the Problem Persists
If all external connections, tubing, and adapters have been verified and the issue continues, the problem is likely internal (e.g., pressure sensors or control system fault).
Remove the unit from service, label it Out of Service, and send for repair or bench evaluation.
Clinical Use Tip
Always complete troubleshooting and verification before using the system for scope reprocessing. Do not troubleshoot on an active patient. Move the patient or scope to a backup device first to ensure therapy continuity and safe reprocessing.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Scope Buddy Plus not detecting connected channels during setup."
Cause
What was observed during troubleshooting.
Example:
"Loose channel tubing connection causing improper pressure sensing."
Resolution
What action was taken.
Example:
"Reconnected tubing securely and verified proper channel detection."
Helpful Details to Include (If Known)
- Channel ports tested and verified
- Tubing condition (kinks, damage, replaced)
- Adapter condition and type used
- Indicator lights or error messages observed
- Known-good scope testing results
- Final device status
Final Thought
Effective troubleshooting starts with simple external checks like connections and tubing integrity. Most channel detection issues are setup-related. Escalate only after these are ruled out, and always prioritize safe reprocessing practices and accurate documentation.
That is successful troubleshooting.
