What This Guide Helps With
Error 22 during auto-load causing tubing not to seat properly, preventing feeding from starting due to motor or pump set engagement failure.
Step-by-Step Troubleshooting
Ensure Patient Safety First
- Remove the pump from patient use if feeding cannot be reliably started
- Transition to a backup feeding pump or alternate method
- Ensure no interruption to patient nutrition delivery
Verify the Reported Error and Behavior
- Power on the pump and attempt to load the tubing set
- Confirm Error 22 appears during auto-load
- Observe if the motor attempts to engage but stops
- Check if tubing fails to fully seat
Reload the Pump Set
- Open the pump door
- Remove tubing completely
- Reinstall tubing following correct routing
- Ensure tubing is properly seated in the rotor track
Inspect Tubing Condition
- Check for kinks, twists, or flattening
- Inspect cassette or tubing segment for wear or deformation
- Replace with a new pump set if any issues are found
Check for Obstructions in Pump Mechanism
- Inspect rotor area for debris or dried formula
- Ensure the rotor path is clear
- Do not force any internal components
Power Cycle the Pump
- Turn the pump off
- Wait 10–15 seconds
- Turn the pump back on
- Attempt auto-load again
Attempt with a New Pump Set
- Use a new, unopened feeding set
- Confirm proper loading behavior
- Observe if the error clears
If the Problem Persists
If Error 22 continues after tubing reload, replacement, and obstruction checks, external causes have been ruled out. This indicates a likely internal motor or mechanical failure.
- Remove the device from service
- Label as Out of Service
- Send for repair or bench evaluation
Clinical Use Tip
Never troubleshoot loading issues on an active patient. Always transition to a backup pump before attempting corrective actions.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Pump displaying Error 22 during tubing auto-load; unable to initiate feeding."
Cause
What was observed during troubleshooting.
Example:
"Motor error during auto-load. Tubing reloaded and replaced with no resolution; internal motor failure suspected."
Resolution
What action was taken.
Example:
"Removed from service, labeled out of 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
Motor-related errors like Error 22 should be approached by ruling out tubing setup and obstruction issues first. Once external causes are eliminated, prompt escalation ensures safe patient care and protects equipment integrity.
That is successful troubleshooting.
