What This Guide Helps With
This guide addresses Error 51 Graphic Display Timeout (Auto Mode Data Write Failure), which can cause the feeding pump to freeze, become unresponsive, or stop operating due to failed communication between internal components.
Step-by-Step Troubleshooting
1. Ensure Patient Safety First
- Stop the feeding pump immediately
- Transfer the patient to a backup feeding pump or alternate method
- Verify feeding continues without interruption
2. Verify the Reported Error and Behavior
- Power on the device and confirm Error 51 is displayed
- Observe if the error appears at startup or during operation
- Check for frozen screen or unresponsive controls
3. Perform a Power Cycle
- Turn the pump OFF
- Disconnect AC power
- Remove and reinsert the battery (if accessible)
- Reconnect power and restart the pump
4. Check Power Stability and Connections
- Verify AC outlet is functional
- Inspect power cord and adapter for damage
- Ensure battery is properly seated
5. Inspect Physical Condition of the Device
- Check for cracks or moisture on the display
- Inspect housing for impact damage
- Confirm buttons respond normally
6. Attempt Operation in Different Modes
- Try running the pump in different feeding modes
- Observe if the error occurs only in auto mode
- Note any consistent failure patterns
If the Problem Persists
If Error 51 continues after external troubleshooting, internal communication between the display and control board is likely failing.
- Remove the device from service
- Label as Out of Service
- Send for repair or board-level evaluation
Clinical Use Tip
Never troubleshoot a feeding pump while connected to a patient. Always transfer the patient to a backup device before beginning troubleshooting.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Pump displaying Error 51 with frozen or unresponsive screen during feeding."
Cause
What was observed during troubleshooting.
Example:
"Confirmed Error 51 persists after power cycle; suspected internal communication failure between display and control board."
Resolution
What action was taken.
Example:
"Removed pump from service and sent for repair after unsuccessful reset and external checks."
Helpful Details to Include (If Known)
- Alarm behavior
- Accessories swapped
- Power behavior
- Environmental factors
- Indicator lights
- Final device status
Final Thought
Error 51 indicates a communication failure within the pump system. While power cycling and external checks should always be performed first, persistent errors require escalation. Acting quickly protects patient safety and ensures efficient troubleshooting.
That is successful troubleshooting.
