What This Guide Helps With
Addresses no flow or weak flushing pressure caused by water supply, tubing, filters, or connection issues affecting proper endoscope flushing.
Step-by-Step Troubleshooting
Ensure Patient Safety First
- Confirm the device is not in use on a scope intended for patient procedures
- Remove from clinical workflow if flushing is required for reprocessing
Verify Water Supply to the Unit
- Confirm facility water supply is on
- Verify no upstream shutoff valves are closed
- Observe for normal inlet pressure if gauge is present
Inspect Inlet Hose and Connections
- Straighten any kinks
- Tighten fittings securely
- Look for leaks or damage
Check Internal and External Filters
- Remove and visually inspect filter screens
- Replace or clean filters if visibly dirty
Verify Proper Channel Hookup
- Confirm correct adapters are being used
- Ensure all connections are fully seated and not leaking
Test Flow Without Scope Connected
- Activate flushing cycle
- Observe output directly from ports
- If flow is strong → issue likely with scope or adapters
- If flow is weak or absent → continue troubleshooting
Inspect for Air in Lines or Priming Issues
- Run multiple flush cycles to purge air
- Observe for sputtering or inconsistent flow
Check for Blockage in Output Tubing or Ports
- Remove tubing and visually inspect
- Flush tubing separately if needed
Evaluate Facility Water Pressure
- Test pressure at the source
- Compare to manufacturer recommended range
If the Problem Persists
If water supply, tubing, filters, and connections have been verified, the issue is likely internal (pump, regulator, or internal valve failure).
Remove the device from service, label it Out of Service, and send for repair or bench evaluation.
Clinical Use Tip
Never troubleshoot on an active patient. Always move the patient or scope to a backup device first to maintain proper therapy and reprocessing continuity.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Scope Buddy reported to have no flow during flushing cycle."
Cause
What was observed during troubleshooting.
Example:
"Clogged inlet filter restricting water flow."
Resolution
What action was taken.
Example:
"Filter cleaned/replaced and flow restored to normal operation."
Helpful Details to Include (If Known)
- Alarm behavior or error indicators
- Accessories or tubing swapped during troubleshooting
- Power or system response during testing
- Environmental or water supply factors
- Indicator lights or system feedback
- Final device status
Final Thought
Flushing issues are almost always caused by external restrictions or supply problems. Systematically checking water supply, filters, and connections ensures safe and effective troubleshooting. Knowing when to escalate prevents wasted time and protects reprocessing integrity.
That is successful troubleshooting.
