What This Guide Helps With
Error 5 indicating battery level not detected, causing power status issues, inaccurate battery readings, or potential unexpected shutdown during use.
Step-by-Step Troubleshooting
Ensure Patient Safety First
- Remove the pump from patient use if actively infusing
- Transition feeding to a backup pump if required
- Confirm nutrition delivery continues without interruption
Verify the Reported Error and Behavior
- Power on the pump and confirm Error 5 is displayed
- Observe if error appears at startup or during operation
- Check if battery indicator is missing or inaccurate
- Determine if pump only runs on AC power
Check AC Power Source
- Plug into a known-good outlet
- Confirm stable power to the device
- Observe if pump operates normally on AC
Inspect Power Cord and Connections
- Inspect AC adapter for damage or fraying
- Ensure secure connection at pump and outlet
- Verify no loose connections
Check Battery Installation and Condition
- Remove and reseat the battery (if removable)
- Inspect for swelling, leakage, or damage
- Confirm correct battery type is installed
Perform a Power Cycle
- Turn off the pump
- Disconnect AC power
- Wait 30–60 seconds
- Reconnect power and restart
Evaluate Battery Charging and Detection
- Observe battery indicator while connected to AC
- Disconnect AC briefly to test battery operation
- Confirm whether battery is detected and supports operation
If the Problem Persists
If Error 5 continues after verifying power, connections, and battery condition, external causes have been ruled out. This indicates failure of the internal battery monitoring circuitry or ADC signal.
- Remove device from service
- Label as Out of Service
- Send for repair or board-level evaluation
Clinical Use Tip
Never troubleshoot a feeding pump while it is actively connected to a patient. Always transition to a backup device before attempting diagnosis.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Pump displaying Error 5 with no battery level indication and unable to confirm battery status."
Cause
What was observed during troubleshooting.
Example:
"Battery monitoring failure due to loss of ADC interrupt signal; battery reseating and power cycling did not resolve issue."
Resolution
What action was taken.
Example:
"Verified AC power and connections. Attempted reset and battery checks. Error persisted. Device 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
Battery monitoring errors directly impact device reliability and patient safety. Always rule out simple external power and battery issues first, then escalate quickly when internal sensing failures are identified.
That is successful troubleshooting.
