What This Guide Helps With
Use this guide when chamber water or condensate handling is abnormal, drainage is incomplete, or expected process levels are not achieved.
Step-by-Step Troubleshooting
1. Protect Patient Care and Prevent Water Hazards
Do not process clinical loads when chamber filling or drainage is unreliable. If water is overflowing, leaking, or accumulating outside the sterilizer, stop operation and isolate the area as needed.
Expected outcome: Clinical loads are redirected and any immediate slip, electrical, or water-damage hazard is controlled.
2. Confirm the Exact Fluid-Handling Problem
Determine whether the chamber does not receive expected water, fills too slowly, fails to drain, retains condensate, or repeatedly stops during a fluid-related phase.
Document any displayed message and the phase where the problem occurs.
Expected outcome: The symptom is clearly identified rather than treating all fill and drain problems as the same failure.
3. Verify Facility Water Availability
Confirm required water supplies are available and that accessible facility valves associated with normal operation have not been unintentionally closed.
Coordinate with Facilities when the building supply is questionable.
Expected outcome: Required water service is available. If restoring an external supply corrects the problem, complete cycle verification and stop troubleshooting.
4. Inspect Accessible Supply Connections
Check external water hoses, piping interfaces, strainers accessible under approved maintenance procedures, and connections for kinks, leaks, obvious blockage, or damage.
Do not disassemble internal valves or piping assemblies.
Expected outcome: External supply paths are intact and unrestricted. If correcting an accessible restriction restores normal operation, verify and stop troubleshooting.
5. Inspect the Chamber Drain Area
When the chamber is cool and safe, inspect accessible drains and screens for debris, packaging material, labels, lint, or other obstruction.
Remove only material accessible without invasive disassembly.
Expected outcome: The drain path is visibly clear. If removal of debris restores drainage, perform an appropriate test cycle and stop troubleshooting.
6. Verify Facility Drainage
Check for evidence of backed-up building drains, slow drainage, nearby plumbing problems, or standing water at the sterilizer drain interface.
Coordinate suspected infrastructure issues with Facilities.
Expected outcome: Facility drainage accepts discharge normally. If a building drain condition is corrected and normal operation returns, verify a complete cycle and stop troubleshooting.
7. Check Loading Conditions
Confirm racks, containers, and load items are positioned normally and are not blocking drainage paths or causing excessive retained water.
Expected outcome: Load configuration is not interfering with chamber drainage or condensate movement.
8. Run an Appropriate Test Cycle
After supply and drain conditions are verified, run an approved test cycle and observe fill, conditioning, drain, and exhaust behavior.
Expected outcome: Chamber fluid handling progresses normally without standing water, repeated interruption, or abnormal leakage. Troubleshooting can stop after acceptable verification.
9. Escalate Persistent Fill or Drain Problems
If external supply, drain, chamber obstruction, and loading conditions are normal but the problem persists, remove the sterilizer from service.
Expected outcome: Internal fluid-control problems are referred for qualified service evaluation.
If the Problem Persists
Common external causes have been ruled out. Remaining categories may include internal valves, level sensing, pressure sensing, drain controls, piping, control outputs, or other service-level fluid-management components.
The sterilizer should be:
- Removed from service.
- Labeled Out of Service.
- Sent for qualified repair or service evaluation.
- Evaluated using manufacturer documentation and approved test equipment.
- Repaired or configured only by qualified personnel.
- Required to complete appropriate functional and process verification before return to service.
Stopping before unnecessary internal plumbing or component disassembly is proper troubleshooting.
Clinical Use Tip
Standing water or incomplete drainage can affect the sterilization process, so do not release loads from a cycle with unresolved chamber-fluid abnormalities.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Sterile Processing reported standing water remained in the Getinge GSS67H chamber after cycles."
Cause
What was observed during troubleshooting.
Example:
"Clinical Engineering found debris obstructing the accessible chamber drain screen."
Resolution
What action was taken.
Example:
"Clinical Engineering removed the debris, verified the drain path was clear, completed an approved test cycle, and confirmed normal chamber drainage."
Helpful Details to Include (If Known)
- Fill, drain, or level symptom
- Cycle phase affected
- Exact displayed message
- Water-supply status
- External valve position
- Visible hose or piping condition
- Drain-screen condition
- Facility drain behavior
- Evidence of leakage
- Test-cycle results
- Final device status
Final Thought
Start with safe isolation, facility water, drainage, accessible connections, and chamber obstructions before considering internal fluid-control faults. Verify normal operation with an appropriate cycle and document what changed.
That is successful troubleshooting.
