What This Guide Helps With
This guide addresses Error: 0 Internal Timer Stopped, which indicates a failure in the pump’s internal timing system. This condition can cause the pump to shut down and prevents safe and reliable enteral feeding delivery.
Step-by-Step Troubleshooting
Ensure Patient Safety First
- Stop the pump if actively infusing
- Transition feeding to a backup pump or approved alternative method
- Verify patient feeding continues without interruption
Verify the Reported Error and Behavior
- Power on the pump and confirm Error: 0 is displayed
- Observe if the error occurs at startup or during operation
- Note if the pump is completely non-functional or intermittent
Check Power Source and Basic Operation
- Verify AC power connection is secure
- Inspect power adapter for damage
- Test operation on both battery and AC power
Perform a Full Power Cycle (Primary Corrective Step)
- Turn the pump off
- Disconnect from AC power
- Wait 30–60 seconds
- Reconnect power and restart the device
Observe Post-Reset Behavior
- Allow the pump to run briefly if safe
- Monitor for recurrence of Error: 0
- Confirm stable operation without faults
Stop if Resolved
- If the error clears, return the device to service
- Monitor closely during initial use
If the Problem Persists
If Error: 0 Internal Timer Stopped continues after power cycling, external causes have been ruled out and an internal control or timing failure is likely.
- 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 while actively connected to a patient. Always transition to a backup pump first to maintain continuous nutrition delivery.

Final Thought
Error: 0 Internal Timer Stopped indicates a critical internal system failure. Proper troubleshooting involves confirming the fault, attempting a safe reset, and escalating appropriately to maintain patient safety and device reliability.
That is successful troubleshooting.
