What This Guide Helps With
Error: PUMP DEF indicating loss of hydraulic pump control causing no table movement or function. This condition prevents all hydraulic positioning and can render the table unusable during procedures.
Step-by-Step Troubleshooting
1. Ensure Patient Safety First
- Remove the table from patient use immediately if movement is unavailable or unpredictable
- Transfer the patient to a safe, functioning surface
2. Verify the Reported Error and Behavior
- Power on the table and confirm Error: PUMP DEF is displayed
- Attempt table movements (height, tilt, etc.)
- Observe for lack of movement and absence of pump sound
3. Check Power Source and Battery Status
- Ensure the table is plugged into mains power
- Verify the power indicator is illuminated
- Check battery charge level if available
4. Inspect Hand Control and Foot Control Operation
- Test both hand control and foot pedal independently
- Ensure no buttons are stuck or continuously pressed
5. Check for Audible or Physical Signs of Pump Activity
- Listen for pump motor sound when commands are given
- Feel for vibration in the base
- Confirm absence of pump response
6. Inspect External Connections and Condition
- Check for visible damage to cables or connectors
- Inspect base for signs of hydraulic fluid leakage
7. Power Cycle the Table
- Turn the table OFF completely
- Disconnect from mains power for 30 seconds
- Reconnect and power ON
If the Problem Persists
If Error: PUMP DEF remains after all external checks:
- External causes have been ruled out
- The issue likely indicates internal power supply or pump control failure
- Remove the device from service
- Label the unit as Out of Service
- Send for repair or bench evaluation
Clinical Use Tip
Never troubleshoot a non-responsive surgical table on an active patient. Always transfer the patient to a backup device before attempting any troubleshooting steps.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Table displaying Error PUMP DEF with no hydraulic movement."
Cause
What was observed during troubleshooting.
Example:
"No pump activation observed after verifying power source and control inputs, indicating internal pump control or power supply failure."
Resolution
What action was taken.
Example:
"Performed external checks and power cycle. Error persisted. Removed from service and sent for repair."
Helpful Details to Include (If Known)
- Alarm behavior
- Accessories swapped
- Power behavior
- Environmental factors
- Indicator lights
- Final device status
Final Thought
PUMP DEF errors indicate a critical loss of hydraulic control. Efficient troubleshooting focuses on confirming power and control inputs before escalating to internal failure. Always prioritize safety and timely removal from service when necessary.
That is successful troubleshooting.
