What This Guide Helps With
Error 109 PIC Encoder Error indicating pump motor position feedback failure, resulting in loss of accurate infusion control or pump stoppage.
Step-by-Step Troubleshooting
Ensure Patient Safety First
- Remove the pump from patient use immediately
- Transfer the infusion to another functioning pump
Verify the Reported Error and Behavior
- Power on the pump and confirm Error 109 PIC Encoder Error is displayed
- Observe when the error occurs (startup, during infusion, intermittent)
Perform a Power Cycle
- Turn the pump off completely
- Disconnect from AC power if connected
- Wait 10–15 seconds and power back on
Inspect Pump Door and Cassette Area
- Open and close the pump door fully
- Check for obstructions, debris, or dried fluid
- Inspect for misalignment or resistance
Check for Cassette/Set Issues
- Remove the current IV set
- Inspect for improper loading or damage
- Load a new, known-good Baxter-approved IV set
Listen and Observe Motor Behavior
- Listen for clicking, grinding, or no movement
- Observe if the pump attempts to actuate
Check for Physical Damage
- Inspect housing and door for impact damage
- Look for signs of fluid ingress
If the Problem Persists
If Error 109 PIC Encoder Error continues after external checks and IV set replacement, internal encoder, motor, or control circuitry failure is likely.
- Remove the pump from service
- Label the device as Out of Service
- Send for qualified repair or bench evaluation
Clinical Use Tip
Never troubleshoot on an active patient. Always transfer therapy to a backup pump before addressing encoder or motion-related errors.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Pump displaying Error 109 PIC Encoder Error during startup; unable to initiate infusion."
Cause
What was observed during troubleshooting.
Example:
"Error persisted after power cycle and IV set replacement; no mechanical obstruction noted, indicating internal encoder or motor feedback failure."
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
Encoder errors represent loss of positional feedback, which is critical for accurate infusion delivery. Always rule out external causes, but escalate promptly when control accuracy is compromised.
That is successful troubleshooting.
