What This Guide Helps With
This guide addresses Error 23 Motor failsafe timeout, which indicates the pump has lost motor or encoder feedback. This condition stops feeding and prevents the pump from operating safely.
Step-by-Step Troubleshooting
1. Ensure Patient Safety First
- Stop the pump immediately if in use
- Transition feeding to a backup device
- Confirm patient feeding continues without interruption
2. Verify the Reported Error and Behavior
- Power on the pump and observe the display
- Confirm Error 23 is present
- Note when the error occurs (startup, priming, or feeding)
- Observe if the pump attempts to run before failing
3. Perform a Power Cycle
- Turn the pump off
- Disconnect AC power if connected
- Wait 10–15 seconds
- Restart the pump
4. Check Pump Set Installation and Rotor Area
- Remove and reinstall the feeding set
- Ensure tubing is properly seated in the rotor
- Inspect rotor area for debris or obstruction
5. Inspect for Physical Resistance or Damage
- Listen for abnormal sounds (grinding or clicking)
- Check for stiffness when loading tubing
- Inspect for signs of impact or contamination
6. Attempt Operation Without Load
- Power on the pump without tubing installed
- Observe if the error appears immediately
- Compare behavior with and without load
If the Problem Persists
If Error 23 continues after completing all external checks:
- External and setup-related causes have been ruled out
- This indicates an internal motor or encoder failure
- Remove the device from service
- Label the unit as Out of Service
- Send for repair or bench evaluation
Clinical Use Tip
Never attempt to troubleshoot or restart a pump with a motor error while connected to a patient. Always switch to a functioning backup device first.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Pump displaying Error 23 and stops feeding during use."
Cause
What was observed during troubleshooting.
Example:
"Motor failsafe timeout indicating loss of encoder feedback; issue persists after power cycle and setup verification."
Resolution
What action was taken.
Example:
"Removed from service, labeled out of service, and sent for repair evaluation."
Helpful Details to Include (If Known)
- Alarm behavior
- Accessories swapped
- Power behavior
- Environmental factors
- Indicator lights
- Final device status
Final Thought
Error 23 reflects a failure in the pump’s motor control system. Once external causes are ruled out, escalation is the correct action. Proper documentation and timely removal from service ensure patient safety and efficient repair handling.
That is successful troubleshooting.
