What This Guide Helps With
Error E7 Compressor Error indicating compressor failure causing loss of therapy and inability to deliver sequential compression.
Step-by-Step Troubleshooting
Ensure Patient Safety First
- Remove the device from active patient use immediately if compression therapy is interrupted
- Apply an alternate SCD unit if therapy is required
- Confirm patient continues prescribed DVT prophylaxis
Verify the Reported Error and Behavior
- Power on the unit and confirm Error E7 Compressor Error is displayed
- Observe if sleeves fail to inflate
- Check for absence of compressor sound or abnormal noise
- Note whether error appears at startup or during operation
Check Power Source and Basic Operation
- Plug into a known-good outlet
- Confirm power indicator is illuminated
- Power cycle the device (turn off, wait, restart)
Inspect Hose Connections and Sleeves
- Ensure tubing is fully connected
- Inspect for kinks, occlusions, or disconnections
- Swap with known-good sleeves and tubing if available
Listen for Compressor Activity
- Listen during startup or attempted inflation
- Check for normal compressor motor sound
- Identify clicking, humming, or complete silence
If the Problem Persists
If Error E7 remains after external checks, external and accessory-related causes have been ruled out. This indicates an internal electrical or mechanical compressor failure.
- Remove device from service
- Label as Out of Service
- Send to Cardinal Health or qualified repair vendor
Clinical Use Tip
Never troubleshoot on an active patient. Move the patient to a backup device first to ensure continuous therapy.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Unit displaying Error E7 Compressor Error and not inflating sleeves during use."
Cause
What was observed during troubleshooting.
Example:
"Compressor not operating and E7 error persisted after verifying power and accessories."
Resolution
What action was taken.
Example:
"Removed device from service and sent to manufacturer for repair."
Helpful Details to Include (If Known)
- Alarm behavior
- Accessories swapped
- Power behavior
- Environmental factors
- Indicator lights
- Final device status
Final Thought
Compressor-related errors directly impact therapy delivery. Always rule out simple airflow issues first, but recognize when internal failures require escalation to protect patient safety and ensure reliable equipment operation.
That is successful troubleshooting.
