What This Guide Helps With
Error E5 Valve Feedback Error indicates a valve malfunction within the device, preventing proper inflation and deflation of compression sleeves and interrupting therapy delivery.
Step-by-Step Troubleshooting
Ensure Patient Safety First
- Remove the device from active patient use immediately
- Apply an alternate SCD unit to maintain DVT prophylaxis
Verify the Reported Error and Behavior
- Power on the device and confirm Error: E5 Valve Feedback Error is displayed
- Observe when the error occurs (startup or during therapy)
- Check if sleeves inflate at all
- Listen for abnormal sounds such as missing or irregular valve actuation
Check Power Source and Perform Reset
- Ensure device is connected to a known-good outlet
- Power cycle the unit (turn off, wait 10–15 seconds, restart)
Inspect Tubing and Sleeve Connections
- Verify tubing is fully seated in ports
- Inspect for kinks, disconnections, or blockages
- Confirm sleeves are properly attached
Check for Obstructions or External Pressure Issues
- Ensure tubing is not compressed under bed wheels or rails
- Check sleeves for folds or improper wrapping
Swap with Known-Good Accessories
- Replace sleeves and tubing with known-good components if available
- Confirm no change in error condition
Evaluate Device Function
- Attempt to start a therapy cycle
- Observe for lack of inflation/deflation
- Confirm immediate return of E5 error
If the Problem Persists
If the error remains after all external checks, internal causes have been confirmed.
- Remove device from service
- Label as Out of Service
- Send to Cardinal Health or authorized service provider for repair
Clinical Use Tip
Never troubleshoot compression devices on an active patient. Always transfer therapy to a functioning backup device first.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Unit displaying Error E5 Valve Feedback Error and sleeves not inflating."
Cause
What was observed during troubleshooting.
Example:
"Persistent E5 error with no valve actuation after verifying tubing, sleeves, and power source."
Resolution
What action was taken.
Example:
"Removed from service, labeled Out of Service, and sent to manufacturer for valve repair. Backup unit provided."
Helpful Details to Include (If Known)
- Alarm behavior
- Accessories swapped
- Power behavior
- Environmental factors
- Indicator lights
- Final device status
Final Thought
Error codes like E5 help quickly identify internal failures. Proper troubleshooting means ruling out all external causes before escalating for repair, ensuring patient safety and efficient service handling.
That is successful troubleshooting.
