Autoclave Repair Tips

The Water Outlet Strainer on your Tuttnauer EZ series should be cleaned on a monthly basis.

Tuttnauer’s design engineers made cleaning the Water Outlet Strainer on you EZ Autoclave easy.  No need to remove the cabinet to gain access.  No tools or Service Technican required

Just a few simple steps:

Start by unplugging your Tuttnauer autoclave from the wall outlet and allowing the autoclave to cool down before proceeding (the Strainer Cap is located on the exhaust line and gets extremely hot). 

Make sure there is no water or pressure remaining in the Tuttnauer autoclave chamber. 

The Water Outlet Strainer is located on the back of the Tuttnauer autoclave.  There are 4 components to the water strainer:

1. The Strainer Cap
2. A Gasket
3. The Strainer Element
4. The Strainer Housing     

To remove the Strainer Element for cleaning, turn the strainer clamp counter-clockwise.  Remove the cap and the gasket.  Pull the Strainer Element out.

Rinse the Strainer Element under running water.  Use a brush if necessary (a tooth brush works very well).  After the Strainer element is clean, reinstall it, along with the gasket and Cap

Tuttnauer EZ Series Autoclave Troubleshooting

The Low Water Message
(Includes the Tuttnauer EZ9 Tuttnauer EZ10 & Tuttnauer EZ10K)

Possible Causes

• A dirty or shorted Water Electrode
• A clogged water pump or water pump filter
• A clogged water line
• Tuttnauer is improperly leveled
• The Air Outlet Valve is stuck closed
• A leaky door gasket, door bellows, solenoid valve, safety valve, or the air jet is allowing steam to escape at a higher than normal rate
• A power down has occurred and on power up the water electrode tip is dry

Replacing The Tuttnauer EZ9 Autoclave HEPA Filter, Requires Only A Screw Driver And A Few Minutes To Complete

Your Tuttnauer EZ9 autoclave is equipped with an air compressor, which allows you to thoroughly dry your sterilized instruments with the door closed.

The way it works is during the drying stage, the compressor forces air through a HEPA filter and forces the air to circulate through the heated Tuttnauer EZ9 autoclave chamber. 

This process removes any moisture from the wrapped instruments, allowing you to put them to work immediately.

The HEPA filter is a bacteriological filter, which delivers clean, bacteria-free air to the compressor.  How often the autoclave is used and the surrounding environment determine how often the filter should be changed on your Tuttnauer EZ9 Autoclave,

A good rule of thumb is to replace the Tuttnauer EZ9 Autoclave HEPA filter at least every 12 months to ensure maximum efficiency.  Replacing the filter regularly not only insures clean, bacteria free air, it also helps to extend the life of the air compressor

The Tuttnauer EZ9 Autoclave HEPA Filter is mounted in an opening on the right sidewall of the autoclave cabinet; this is to allow easy access for replacing it (See picture above) and something you can easily do

To replace the Tuttnauer EZ9 HEPA Filter, just follow these simple instructions:

1. Remove the securing screws and then the filter cover by turning the cover counter-clockwise until the handle is at a vertical position.

2. Pull out the cover with the filter attached.

3. Disconnect the flexible tube from the filter

4. Replace the filter with a new one connecting it to the flexible tubing.

5. Reassemble the cover and lock it into position by turning it a ¼ turn.

6. Fasten the securing screws.

Tip:  Remove all of the guesswork:  Place a small piece of tape or a label next to the cover of your Tuttnauer EZ9 autoclave with the next scheduled replacement date

Having heat problems with your  Tuttnauer 2540M Autoclave?   Wondering if it could be the heating elements?  Now you can know for sure

How To Test The Tuttnauer 2540M Heater Element

This test consists of measuring the amount of resistance in the Tuttnauer 2540M Heating Element. To do this, first, turn the Tuttnauer autoclave off and unplug it from the wall

WARNING: CURRENT MUST NOT BE PRESENT WHEN MEASURING RESISTANCE.

Remove the cabinet from the Tuttnauer 2540M to give you access to the heating elements.  Then test each one.  Do not stop after you have found a defective element, test each one.

Set your volt/ohm meter on 200 ohms (200 NOT 200k). The ohms range is located within the Omega ( O )(look for this symbol) section of your meter. It is also the area with “k” ranges (ie: 2000k,. 200k, 20K and then 2000, 200).

Disconnect the wires from each heating element before testing to keep from getting a false reading. 

Place a probe from the volt/ohm meter on each terminal of the 2 terminals on the Tuttnauer 2540M element (it really doesn’t matter which color probe goes where).

For the Tuttnauer 2540M 120v model, heating element to be good, it must  measure  between 36.9 and 45.1 ohms .   If your reading is outside of this range, then it is defective and needs to be replaced.

Replacing the Heating Elements on the Tuttnauer 2540M is not difficult and does not require any special tools.  And it is something you can do.
