What This Guide Helps With
This guide addresses Error 7, which indicates a failure in the pump’s ability to detect upstream occlusions or an empty feeding bag. This can result in interrupted feeding or unsafe continuation of feeding without proper monitoring.
Step-by-Step Troubleshooting
1. Ensure Patient Safety First
- Remove the pump from active patient use if feeding is interrupted or unreliable
- Transition feeding to a backup pump or method
2. Verify the Reported Error and Behavior
- Power on the pump and confirm Error 7 is displayed
- Attempt to start a feeding cycle
- Note when the error occurs (startup or during feeding)
3. Check Feeding Bag and Setup
- Ensure feeding bag contains formula and is not empty
- Verify the bag is properly hung and not collapsed
- Confirm tubing is correctly loaded into the pump
4. Inspect Tubing for Occlusion or Restriction
- Check tubing from bag to pump for kinks or clamps
- Ensure there is no blockage or pinching
- Re-seat tubing properly in the pump channel
5. Power Cycle the Pump
- Turn the pump OFF
- Wait 10–15 seconds
- Power ON and attempt operation again
6. Swap with Known Good Setup
- Use a different feeding bag and tubing set
- Attempt to run the pump
- Determine if the issue follows the accessories or remains with the device
7. Determine Device Condition
- If all external checks pass, suspect internal sensor or ADC failure
- This condition cannot be corrected through external troubleshooting
If the Problem Persists
All external causes have been ruled out. The issue is likely due to internal failure of the upstream occlusion or bag-empty detection system.
- Remove the device from service
- Label Out of Service
- Send for repair or replace the unit
Clinical Use Tip
Never troubleshoot a feeding pump while it is connected to a patient. Always transition the patient to a backup device before performing any troubleshooting steps.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Pump displaying Error 7 and not detecting empty feeding bag during use."
Cause
What was observed during troubleshooting.
Example:
"Internal failure of upstream occlusion/bag-empty detection sensor after verifying proper setup and tubing."
Resolution
What action was taken.
Example:
"Tested with known good accessories and power cycled unit. Error persisted. Removed from service and sent for repair."
Helpful Details to Include (If Known)
- Alarm behavior
- Accessories swapped
- Power behavior
- Environmental factors
- Indicator lights
- Final device status
Final Thought
Error 7 reflects a failure in the pump’s ability to detect critical feeding conditions. Proper troubleshooting focuses on ruling out setup issues quickly and escalating when internal faults are confirmed. Accurate detection is essential for safe patient care.
That is successful troubleshooting.
