What This Guide Helps With
Error: PUMP FAIL where the hydraulic pump runs continuously, causing unintended table movement or potential system overheating.
Step-by-Step Troubleshooting
1. Ensure Patient Safety First
- Remove the table from patient use immediately
- Ensure the table is stable and not actively moving
- Transfer the patient to a safe surface if needed
2. Verify the Reported Error and Behavior
- Power on the table and confirm “PUMP FAIL” is displayed
- Observe if the hydraulic pump runs continuously without input
- Note when the issue occurs (startup vs during operation)
3. Check Hand Control and Foot Pedal for Stuck Inputs
- Inspect all buttons for sticking or damage
- Press and release each button to verify proper function
- Disconnect hand control (if safe) and observe behavior
4. Inspect Control Cables and Connections
- Check for pinched, damaged, or worn cables
- Verify connectors are fully seated
- Ensure no contamination in connectors
5. Power Cycle the Table
- Turn the table OFF
- Wait 30 seconds
- Turn the table back ON
- Observe if the pump starts immediately
6. Verify Power Supply Behavior
- Connect the table to mains power
- Listen for pump activation during startup
- Confirm pump only runs when commanded
If the Problem Persists
If all external controls, cables, and power conditions have been ruled out and the pump continues running:
- Remove the device from service
- Label the device as Out of Service
- Send the unit for repair or bench evaluation
- Power supply or control board replacement is typically required
Clinical Use Tip
Never troubleshoot a surgical table on an active patient. Uncontrolled hydraulic movement can create serious safety risks. Always transfer the patient to a backup device first.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Table displaying Error: PUMP FAIL with hydraulic pump running continuously without input."
Cause
What was observed during troubleshooting.
Example:
"Pump continued running after verifying controls and cables, indicating internal control circuit failure."
Resolution
What action was taken.
Example:
"Removed from service and sent for repair. Power supply replaced to resolve issue."
Helpful Details to Include (If Known)
- When the pump begins running (startup vs during use)
- Results of control isolation testing
- Power cycle behavior
- Cable condition and connector status
- Any abnormal sounds or overheating
- Final device status
Final Thought
Continuous pump operation is a high-risk condition. Always rule out external inputs first, but recognize when persistent behavior indicates internal failure requiring escalation.
That is successful troubleshooting.
