What This Guide Helps With
Addresses overheating, visible steam or water leakage, and water-on-floor conditions requiring immediate safety action and controlled external inspection.
Step-by-Step Troubleshooting
1. Stop Use and Protect Personnel
If the sterilizer is overheating, leaking steam or hot water, producing a burning odor, or creating water on the floor, stop clinical use immediately.
Keep personnel clear of hot surfaces and fluids. Address slip and electrical hazards according to facility safety procedures. Do not open the door while the chamber may be pressurized.
Expected outcome: Personnel are protected and the unsafe condition is contained.
2. Remove the Sterilizer From Service
Cancel operation using normal controls when it is safe to do so. Disconnect power only when this can be performed without entering standing water or creating another hazard.
Tag the sterilizer Out of Service if the source of the condition is not immediately identified and corrected safely.
Expected outcome: The malfunctioning sterilizer is no longer available for clinical processing.
3. Identify the Type and Location of the Problem
Determine whether the condition is excessive external heat, steam leakage, water leakage, chamber overflow, drainage backup, or water originating from nearby plumbing or another device.
Do not assume water on the floor came from the sterilizer without checking the surrounding area.
Expected outcome: The general source and nature of the hazard are identified.
4. Check for External Plumbing or Drainage Causes
When safe, inspect accessible water connections, drain routing, hoses, reservoirs, and nearby plumbing for disconnection, kinks, overflow, or leakage.
Expected outcome: External infrastructure is either identified as the source or ruled out.
5. Inspect the Door and Accessible Seal
After the sterilizer is cool, depressurized, and safe, inspect the door gasket and sealing surfaces for debris, visible displacement, contamination, or damage.
Expected outcome: An obvious external door-seal problem is either corrected safely or ruled out.
6. Inspect Chamber and Accessible Drainage Areas
Check for debris, excessive retained water, or an accessible drain obstruction that could contribute to overflow or leakage.
Expected outcome: The chamber drainage path is visibly clear of simple external obstruction.
7. Examine for Evidence of Electrical or Thermal Damage
Inspect accessible areas for melted material, discoloration, burning odor, damaged power connections, or abnormal heat.
If any evidence of electrical or thermal damage is present, do not energize the sterilizer again.
Expected outcome: Unsafe electrical or thermal damage is identified before additional testing.
8. Perform a Controlled Leak Check Only When Safe
If a simple external cause was corrected and no electrical or thermal hazard exists, perform an approved controlled operational test while observing for renewed leakage or abnormal heating.
Do not leave the unit unattended during the test.
Expected outcome: The sterilizer remains dry externally and operates without abnormal heat. If leakage recurs, stop immediately.
9. Perform Complete Functional Verification
When the condition has been corrected, complete the required operational and sterilization-process verification. Confirm there is no water accumulation, external steam leakage, abnormal temperature condition, or recurrence.
Expected outcome: The sterilizer operates safely and all required process checks pass. Troubleshooting can stop.
10. Escalate Any Unexplained or Recurrent Condition
If the source of overheating or leakage is not clearly external and correctable, or the condition recurs during testing, do not continue troubleshooting in place.
Expected outcome: The unit is removed from service for controlled bench or manufacturer-supported evaluation.
If the Problem Persists
Accessible plumbing, drainage, door sealing, and environmental causes have been checked. Remaining causes may involve internal plumbing, valves, heaters, pumps, temperature or pressure sensing, control systems, insulation, or other service-level failures.
Remove the sterilizer from service, label it Out of Service, and send it for repair or bench evaluation. Use appropriate Tuttnauer documentation and approved test equipment. Internal repair or configuration should be performed only by qualified personnel.
Following repair, complete leak checks, operational verification, electrical safety testing when appropriate, and all required sterilization-process checks before return to service. Knowing when to stop external troubleshooting is proper troubleshooting.
Clinical Use Tip
Treat steam, hot-water leakage, and unexplained overheating as immediate personnel-safety concerns before considering equipment uptime.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Sterile Processing reported water collecting beneath the Tuttnauer T-Edge 10 during operation."
Cause
What was observed during troubleshooting.
Example:
"Clinical Engineering found an accessible external drain hose kinked and restricting normal discharge."
Resolution
What action was taken.
Example:
"The hose routing was corrected, the area was dried, and the sterilizer completed a monitored verification cycle without leakage before return to service."
Helpful Details to Include (If Known)
- Overtemperature, steam leak, water leak, or floor-water condition
- Exact leak location
- Chamber state when condition occurred
- External hose and drain condition
- Door gasket condition
- Evidence of burning odor or discoloration
- Whether water contacted electrical components
- Results of controlled verification
- Recurrence during testing
- Required process-verification results
- Final device status
Final Thought
Overheating and leakage demand immediate attention to personnel and electrical safety. Confirm simple external plumbing, drainage, and sealing causes only after the sterilizer is safe, and escalate promptly when the source is internal, uncertain, or recurrent.
That is successful troubleshooting.
