What This Guide Helps With
Error 114 Sensor disparity (slow) indicating motor slowdown, causing inaccurate infusion delivery or pump stoppage.
Step-by-Step Troubleshooting
Ensure Patient Safety First
- Remove the pump from patient use immediately if actively infusing
- Transition infusion to a backup pump
- Ensure therapy continues without interruption
Verify the Reported Error and Behavior
- Power on the pump and confirm Error 114 Sensor disparity (slow) is displayed
- Observe when it occurs (startup, priming, or during infusion)
- Listen for sluggish or inconsistent motor movement
Check Cassette and Set Installation
- Remove and reinstall the IV set/cassette
- Ensure proper seating and full latch engagement
- Verify there is no resistance when closing the door
Inspect IV Set and Fluid Path
- Check tubing for kinks or occlusions
- Ensure all clamps are open
- Assess for high resistance in the fluid path
Check for Mechanical Resistance
- Run the pump without a cassette and listen for smooth motor operation
- Reinstall cassette and observe for motor strain during priming
Try a Known-Good IV Set
- Replace the IV set with a new Baxter-approved set
- Reattempt operation
Check Environmental and Physical Condition
- Inspect for debris in cassette area
- Check for signs of fluid ingress
- Look for physical damage or wear
Power Cycle the Pump
- Turn the pump off
- Wait 10–15 seconds
- Restart and observe for error recurrence
If the Problem Persists
If Error 114 continues after all external checks:
- External causes have been ruled out
- The issue likely indicates internal motor degradation, drive mechanism wear, or sensor feedback mismatch
- Remove the pump from service
- Label Out of Service
- Send for repair or bench evaluation
Clinical Use Tip
Never troubleshoot a pump with motor-related errors on an active patient. Always transition to a backup device first to ensure safe and accurate medication delivery.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Pump displaying Error 114 Sensor disparity (slow); infusion slowing or stopping during use."
Cause
What was observed during troubleshooting.
Example:
"Verified cassette placement and tubing condition; replaced IV set with no change. Motor operation sluggish, indicating internal resistance or sensor mismatch."
Resolution
What action was taken.
Example:
"Removed pump from service and sent to Biomed for repair and evaluation."
Helpful Details to Include (If Known)
- Alarm behavior
- Accessories swapped
- Power behavior
- Environmental factors
- Indicator lights
- Final device status
Final Thought
Motor slowdown conditions directly affect infusion accuracy and should be treated as high-risk issues. Always rule out external resistance first, but escalate quickly when performance is inconsistent. Proper removal from service and clear documentation protects both the patient and clinical team.
That is successful troubleshooting.
