What This Guide Helps With
Error 8 indicates a failure in downstream occlusion detection. This prevents the pump from identifying blockages, which can lead to unsafe pressure buildup or interruption of enteral feeding.
Step-by-Step Troubleshooting
Ensure Patient Safety First
- Stop the feeding pump immediately
- Remove from active patient use
- Transition to a backup feeding pump or method
Verify the Reported Error and Behavior
- Power on the pump and confirm Error 8 is displayed
- Observe whether the error appears at startup or during feeding
- Note if the pump stops immediately or alarms during operation
Perform a Power Cycle
- Turn the pump off
- Disconnect from AC power if connected
- Wait 10–15 seconds
- Power the unit back on
Inspect Feeding Set and Downstream Path
- Remove and reseat the feeding set
- Check tubing for kinks, clogs, or closed clamps
- Ensure proper loading of the set in the pump
Try a Known-Good Feeding Set
- Replace with a new, compatible feeding set
- Reload and attempt to run the pump
Observe for Additional Symptoms
- Listen for abnormal motor sounds
- Check for additional error codes
- Observe display responsiveness
If the Problem Persists
If Error 8 continues after power cycling and verifying external components:
- External and setup-related causes have been ruled out
- The pump cannot reliably detect downstream occlusions
Remove the device from service, label it Out of Service, and send for repair or replacement.
Clinical Use Tip
Never troubleshoot or continue using a feeding pump on an active patient. Always transfer the patient to a properly functioning device before troubleshooting.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Pump displaying Error 8 and not detecting downstream occlusions; feeding interrupted."
Cause
What was observed during troubleshooting.
Example:
"Internal ADC/sensor failure for downstream occlusion detection confirmed after power cycle and setup verification."
Resolution
What action was taken.
Example:
"Removed pump from service and sent for repair; provided backup unit for patient use."
Helpful Details to Include (If Known)
- Alarm behavior
- Accessories swapped
- Power behavior
- Environmental factors
- Indicator lights
- Final device status
Final Thought
Error codes involving detection systems are critical safety indicators. Once external causes are ruled out, continued use is unsafe and escalation to repair is required.
That is successful troubleshooting.
