What This Guide Helps With
Error 353.6650 indicating linear sensor failure causing halted or inaccurate infusion due to invalid actuator position feedback.
Step-by-Step Troubleshooting
Ensure Patient Safety First
- Remove the pump from patient use immediately if actively infusing
- Transition infusion to a backup pump
- Verify therapy continues safely on an alternate device
Verify the Reported Error and Behavior
- Power on the pump and confirm Error 353.6650 is displayed
- Observe when the error occurs (startup vs infusion start)
- Listen for abnormal clicking, grinding, or stalled motor sounds
- Check if the pump attempts to run before alarming
Check Administration Set (Pump Module Setup)
- Remove and reseat the administration set
- Ensure correct BD-approved Alaris set is used
- Verify tubing is properly routed through the pumping channel
- Confirm the pump door is fully closed and latched
Inspect Pump Channel and Actuator Area
- Open the pump door and inspect for debris or dried fluid
- Check for contamination or residue from prior spills
- Ensure no obstruction along the actuator track
- Clean using approved methods if needed
Check for Mechanical Obstruction
- With no set installed, observe actuator movement during power-up if visible
- Listen for restricted or stalled motion
- Verify smooth, consistent actuator travel
Power Cycle the Pump Module
- Turn the pump off and wait 10–15 seconds
- Power the unit back on
- Check if the error clears
Test with a Known Good Administration Set
- Install a new, known-good BD Alaris IV set
- Attempt normal operation
- Observe whether the error returns
If the Problem Persists
If Error 353.6650 continues after all external checks:
- External causes have been ruled out
- The issue likely indicates internal linear sensor failure, actuator feedback issue, or calibration fault
- Remove the device from service
- Label the device Out of Service
- Send for repair or bench evaluation
Clinical Use Tip
Never troubleshoot a pump with an active patient connected. Always transfer the patient to a backup device before evaluating the issue.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"BD Alaris pump displaying Error 353.6650 (Linear Sensor output out of range). Infusion would not start."
Cause
What was observed during troubleshooting.
Example:
"After verifying proper set installation, cleaning pump channel, and testing with known good administration set, error persisted indicating internal sensor or actuator feedback failure."
Resolution
What action was taken.
Example:
"Pump removed from service, labeled out of service, and sent to Biomed/vendor for repair."
Helpful Details to Include (If Known)
- Alarm behavior
- Accessories swapped
- Power behavior
- Environmental factors
- Indicator lights
- Final device status
Final Thought
Sensor-related errors indicate the pump cannot confirm safe fluid delivery. After ruling out setup issues, prompt escalation ensures patient safety and proper device handling.
That is successful troubleshooting.
