What This Guide Helps With
Pump not running or inconsistent flushing flow due to power, tubing setup, fluid supply, or blockage issues.
Step-by-Step Troubleshooting
Ensure Patient Safety First
- Do not troubleshoot while a scope is in use on a patient. Remove the scope and use an alternate flushing method if needed.
- Expected: No patient is connected during troubleshooting
- Why it matters: Prevents contamination risk and ensures proper reprocessing workflow
Verify Power to the Unit
- Confirm the unit is plugged in and powered on. Check outlet and power cord.
- Ensure power switch is ON
- Test outlet with another device
- Inspect power cord for damage
- Expected: Unit powers on and indicators illuminate
- Why it matters: No pump activation occurs without proper power
Confirm Pump Activation Behavior
- Attempt to activate the pump using the control interface.
- Press start/activate control
- Listen for pump motor engagement
- Observe for any indicator lights or alarms
- Expected: Pump motor engages and begins flow
- Why it matters: Determines if this is a control issue vs flow issue
Check Fluid Supply Source
- Ensure adequate fluid is available and properly connected.
- Verify fluid container is not empty
- Confirm intake tubing is fully submerged
- Check for kinks or disconnections
- Expected: Continuous fluid supply to pump
- Why it matters: Air intake or empty supply will cause no flow or inconsistent flow
Inspect Tubing and Connections
- Check all tubing for restrictions or improper setup.
- Verify tubing is correctly routed
- Look for kinks, twists, or compression points
- Reseat all quick-connect fittings
- Expected: Tubing is unobstructed and securely connected
- Why it matters: Flow inconsistencies are commonly caused by partial blockages or loose connections
Check for Air in the System (Prime Issue)
- Air in the line can prevent proper pump operation.
- Prime the system per normal operation
- Observe for air bubbles in tubing
- Expected: Steady fluid flow without air gaps
- Why it matters: Air interrupts consistent pump flow and pressure
Inspect Filters or Inline Components (If Equipped)
- Some setups include filters or check valves.
- Inspect for clogging or saturation
- Replace if visibly obstructed
- Expected: Clear, unobstructed flow path
- Why it matters: Blocked filters restrict or stop flow entirely
Evaluate for Blockage at Output/Scope Connection
- Disconnect the scope and test flow directly.
- Run pump with output disconnected from scope
- Observe flow rate
- Expected: Strong, consistent flow from output
- Why it matters: Determines if blockage is in scope vs device
Listen for Abnormal Pump Behavior
- Mechanical issues may present as sound changes.
- Listen for grinding, clicking, or silence when activated
- Expected: Smooth, consistent pump sound
- Why it matters: Abnormal sounds suggest internal pump or motor failure
If the Problem Persists
If power, tubing, fluid supply, and external flow restrictions have been ruled out, the issue is likely internal (pump motor, control board, or internal blockage).
Remove the unit from service, label it Out of Service, and send for repair or bench evaluation.
Knowing when to stop prevents unnecessary risk and improper reprocessing.
Clinical Use Tip
Never attempt to troubleshoot or flush a scope while it is connected to a patient. Always use a backup system to maintain proper infection control standards.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Scope Buddy pump not activating and inconsistent flushing reported by staff."
Cause
What was observed during troubleshooting.
Example:
"Intake tubing partially kinked and air present in line causing intermittent flow."
Resolution
What action was taken.
Example:
"Corrected tubing routing, re-primed system, and verified consistent flow restored."
Helpful Details to Include (If Known)
- Outlet tested and verified
- Pump activation response (yes/no)
- Tubing condition and routing checked
- Fluid level verified
- Presence of air bubbles
- Flow observed with scope disconnected
- Any abnormal pump sounds
- Final operational status
Final Thought
Effective troubleshooting starts with simple external checks—power, fluid, and tubing—before assuming failure. Maintaining proper flow is critical for safe endoscope reprocessing, and escalation at the right time protects both patients and equipment.
That is successful troubleshooting.
