How frequently does my autoclave need preventative maintenance?

The Center for Disease Control (CDC) requires Preventative Maintenance to be conducted on a routine basis. The organization states: “Perform preventive maintenance on sterilizers by qualified personnel who are guided by the manufacturer’s instruction.”

Following preventative maintenance, Duraline can provide a certification label for each autoclave it services – this is a necessary requirement when an inspection is conducted.

Autoclave manufacturers typically recommend that Preventative Maintenance be carried out every 6-12 months, depending on the make/model or how frequently the autoclave is used.

This information can be found in the Operators Manual that is included with the equipment. Advanced autoclaves, such as the Tuttnauer EZ9Plus and EZ11Plus, include an LCD screen on the control panel that alerts users when a simple maintenance check is needed.

Duraline Systems calls to remind its customers when an autoclave preventative maintenance is due.   

Why do autoclaves need preventative maintenance?

Just as it is necessary to change the oil on a car regularly and have annual services, the same is true of an autoclave as proper maintenance extends the life of the machine.

Preventative maintenance ensures:

  1. The autoclave will operate at 100% performance
  2. Instruments are being properly sterilized with each and every cycle
  3. Reduced need for emergency service calls
  4. Risk to patients and staff is decreased
  5. Medical offices are in compliance and following best practices

What happens in routine maintenance?

Preventative maintenance is conducted by Duraline’s certified biotechnicians, which include:

  • Clean the reservoir, chamber, trays and door
  • Clean and inspect the sensors, valves and condenser coils
  • Electrical safety checks and safety inspections
  • Provide a comprehensive service report
  • Replace filters and gaskets as needed
  • Verify temperature, test and calibrate the sterilizer

What maintenance is required by staff?


Clean door gasket and cassette seal with soft cloth or sponge and mild detergent.


The autoclave chamber (or StatIM cassette), trays and door gasket must be cleaned and thoroughly rinsed each week using a mild detergent and water. A Duraline cleaning kit offers the recommended cleaner and scrub pad.

Use the appropriate autoclave cleaner for descaling the autoclave’s chamber, copper tubes and reservoir.   Technicians recommend DuraClean as the most effective cleaner for descaling an autoclave.

For StatIM’s, use Stat-Dri to coat the interior of the cassette every ten cycles.

For Tuttnauer autoclaves, the air jet and water sensor should be cleaned weekly, as well as cleaning the oil door pins and the tightening bolt.


Each month, drain and refill the used distilled water in the reservoir. Clean and check the safety valve and clean the chamber’s strainer. Take out the rack and trays for cleaning and use a mild detergent to clean the chamber thoroughly and then rinse the rack, trays and chamber with water.


To facilitate the appropriate supply of clean air throughout the drying cycle, it is necessary to change the HEPA air filters on StatIM’s and Tuttnauer autoclaves. For StatIM’s, the air filter, cassette seal and biological air filter must be replaced every 500 cycles or 6-months (whichever comes first).


The door gasket should be replaced annually - or as necessary. The majority of autoclave parts are easy to replace; Duraline stocks thousands of parts and can help you replace the part with a quick telephone consultation.

Users can contact Duraline to have a professionally certified biotechnician carry out the replacement.
