What This Guide Helps With
Error 13 Timeout during buzzer test indicates the pump failed its internal audible alarm self-test. This can cause startup failure or loss of audible alarms, which are critical for detecting unsafe feeding conditions.
Step-by-Step Troubleshooting
1. Ensure Patient Safety First
- Remove the pump from patient use immediately if alarms are not functioning
- Transfer feeding to a backup pump or alternate method
- Verify patient therapy is not interrupted
2. Verify the Reported Error and Behavior
- Power on the pump and observe startup
- Confirm “Error 13” is displayed
- Listen for missing or incomplete buzzer tones
- Note if the pump halts operation
3. Perform a Power Cycle
- Turn the pump off
- Disconnect from AC power
- Remove the battery if accessible
- Wait 30–60 seconds
- Reconnect power and restart
4. Inspect for Physical Damage or Contamination
- Check for cracks or signs of liquid intrusion
- Inspect buzzer/speaker openings for debris or blockage
- Listen for faint or distorted sound during startup
5. Confirm Alarm Functionality (If Unit Powers On)
- Trigger an alarm condition (e.g., open door)
- Verify audible alarm is present and clear
- Compare volume and clarity to normal operation
6. Isolate as Internal Failure
- If error persists, internal buzzer test is failing
- Indicates inability to verify alarm output
- Likely buzzer circuit or control board failure
If the Problem Persists
External causes have been ruled out. A persistent Error 13 indicates internal failure of the buzzer system or control circuitry.
- Remove the pump from service
- Label the device as Out of Service
- Send for repair or replace the unit
Clinical Use Tip
Never troubleshoot or use a feeding pump on an active patient if audible alarms are not functioning. Always transfer the patient to a properly functioning device first.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Pump displaying Error 13 during startup; no audible alarm present."
Cause
What was observed during troubleshooting.
Example:
"Buzzer self-test timeout indicating internal alarm circuit failure."
Resolution
What action was taken.
Example:
"Power cycled unit with no change. Removed from 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
Audible alarms are a critical safety feature of feeding pumps. If the device cannot verify alarm functionality during startup, it cannot be trusted in clinical use. Prompt removal from service ensures patient safety and proper escalation.
That is successful troubleshooting.
