What This Guide Helps With
Error E6 indicating internal software failure causing device startup interruption or unreliable compression therapy.
Step-by-Step Troubleshooting
1. Ensure Patient Safety First
- Remove the device from active patient use immediately if the error is present
- Transition the patient to a functioning SCD unit
- Ensure therapy continuity with alternate equipment
2. Verify the Reported Error and Behavior
- Power on the device and confirm that Error E6 appears
- Observe when the error occurs (startup vs during operation)
- Check if therapy stops when the error appears
- Determine if the error is persistent or intermittent
3. Perform a Power Cycle (Basic Reset Attempt)
- Turn the device off
- Unplug from AC power
- Wait 30–60 seconds
- Reconnect power and restart the device
4. Verify Power Source Stability
- Plug the device into a known good outlet
- Test the outlet with another device
- Avoid using power strips or extension cords
5. Inspect External Connections and Accessories
- Disconnect all tubing and sleeves
- Inspect connectors for damage or contamination
- Check for any signs of fluid ingress
6. Reattempt Startup Without Load
- Power on the device with no accessories attached
- Observe if the error appears during startup diagnostics
If the Problem Persists
If Error E6 continues after power cycling and external checks, internal software diagnostics have detected a failure that is not user-correctable.
- Remove device from service
- Label the unit as Out of Service
- Send to manufacturer or qualified repair vendor for service
Clinical Use Tip
Never troubleshoot or restart the device while it is actively being used on a patient. Always transfer therapy to a backup device first.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Device displaying Error E6 Software Error during startup; compression therapy not initiated."
Cause
What was observed during troubleshooting.
Example:
"Internal software/processor diagnostic failure indicated by persistent E6 error after power cycle and external checks."
Resolution
What action was taken.
Example:
"Removed device from service, labeled out of service, and sent to vendor for repair."
Helpful Details to Include (If Known)
- Alarm behavior
- Accessories swapped
- Power behavior
- Environmental factors
- Indicator lights
- Final device status
Final Thought
Software-related errors like E6 represent internal system failures identified by built-in diagnostics. Proper troubleshooting involves confirming the condition, ruling out external factors, and escalating appropriately to protect patient safety and equipment integrity.
That is successful troubleshooting.
