What This Guide Helps With
Error: 12 Stopcock timeout indicates a failure of the internal valve or stopcock mechanism to actuate within the expected time. This can interrupt feeding and prevent the pump from delivering nutrition safely.
Step-by-Step Troubleshooting
1. Ensure Patient Safety First
- Remove the pump from patient use if actively infusing
- Transition feeding to a backup pump or alternate method
- Confirm feeding continues without interruption
2. Verify the Reported Error and Behavior
- Power on the pump and confirm “Error: 12” is displayed
- Note when the error occurs (startup or during feeding)
- Listen for internal movement or lack of mechanical actuation
3. Perform a Power Cycle
- Turn the pump off
- Wait 10–15 seconds
- Power the pump back on
- Observe if the error clears
4. Inspect Pump Set and Loading
- Remove and reinstall the feeding set
- Ensure tubing is properly seated in the pump channel
- Verify a correct and compatible Kangaroo set is being used
5. Check for Obstructions or Resistance in Flow Path
- Inspect tubing for kinks or occlusions
- Ensure all clamps are open
- Verify formula is able to flow freely
6. Observe Mechanical Function
- Start a feed cycle
- Listen for normal internal valve or motor movement
- Note any abnormal sounds (clicking, grinding, or no movement)
If the Problem Persists
If Error: 12 continues after all external checks:
- External causes have been ruled out
- The issue likely indicates internal stopcock or valve control failure
- Remove the device from service
- Label the unit as Out of Service
- Send for repair or replace the unit
Clinical Use Tip
Never troubleshoot a feeding pump with internal control errors while connected to a patient. Always transition to a functioning device first to prevent interruption in nutrition delivery.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Pump displaying Error 12 Stopcock timeout and unable to deliver feeding."
Cause
What was observed during troubleshooting.
Example:
"Error persisted after power cycle, proper set loading, and tubing checks, indicating internal stopcock/valve control failure."
Resolution
What action was taken.
Example:
"Removed pump from service after external checks; 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
Error: 12 reflects a timing failure in a critical internal flow control component. After verifying setup and flow conditions, timely escalation prevents unnecessary troubleshooting delays and ensures patient safety.
That is successful troubleshooting.
