Detailed below is a list of errors which may appear on your unit’s display. Click on an error to see the possible cause and what action should be taken.

If the DAC UNIVERSAL displays an error, you cannot be sure that a complete cycle has been carried out and therefore the instruments are not sterile – so you must start a complete new cycle.

If an error occurs during sterilisation, the display will, when the lid opens, show that an error has occurred during sterilisation. In order to clear this error and start a new complete cycle - you need to press the “M”-button together with the “C”-button (This will also be indicated in the display)

If the error light is flashing without giving an alarm signal, it is because the machine has reached 3000 cycles or it has been 24 months since the last service. Contact our service team in order to do a biennial service on the DAC UNIVERSAL autoclave. Meanwhile the machine can still be used if only the error light is flashing and no other error codes are visual in the display.

In case of an error, an alarm will sound and the error will be displayed visually.

Please note the error code before resetting the alarm. Pressing C resets the alarm.

When pressing C the lid will open for approx. 2 seconds raise and then stop, until the temperature is below 104⁰C/219.2⁰F, following which it will open completely.

Do not open if the temperature is more than 104⁰C/219.2⁰F (⁰C indicated in the display), hot steam may come out of the chamber.

If you do not find the error below or the action you take does not solve the problem, please contact our support team on 08700 10 20 46. In order to help you, have the serial number of your unit and a detailed description of the error ready.



Wipe up possible spilled water after filling.

If there is still a leakage, please call our service team on 0800 028 4749.

Note: If the water is filled into the tank too abruptly or the tank is overfilled, the water may leak onto the table. 

Water in chamber after cycle


Clean or change the filter.

Check that the drain tube is not blocked or broken.

Empty the drain tank if full.

Condensation in instruments


If the instruments are to be stored for a longer period (e.g. during the weekend), it is important that they are blown through (horizontal) manually with compressed air in order to remove condensation in the instruments - as condensation can cause corrosion in the instruments.

Note: Be sure to use compressed air at pressure-level (bar) in accordance with the user manual/instructions from the manufacturer of the instruments.

After the instruments have been blown through they must be wrapped.

Loose adapters


Tighten the adapter with the enclosed Allen key.

Wrong liquid


If liquids other than demineralised or distilled water has been filled into the water tank, then the DAC UNIVERSAL must not be used.

Call our service team on 0800 028 4749.

Sterilisation OFF Press safety ring! (simultaneously a long acoustic alarm is given)


Your DAC Universal engineer has been running a special-programme.

Very Important: Disconnect the power-cable of the DAC Universal and connect it again. If this is not done sterilisation phase will NOT take place! 

What tests do you need to perform on the DAC universal?

On a daily basis, with each cycle run, a class 5 integrator needs to be put in the clip provided to ensure that the DAC reaches the correct temperature and sterilises successfully. The code for these tests is IMS-1241.

How often should you use a Nitraclean tablet?

This should be used once every 50 cycles or once weekly. The Nitraclean tablet will degrease the internals of the DAC and help maintain its effectiveness.

How often should you change the oil filter?

The oil filter should be removed weekly and rinsed under running water. This should then be changed for a new filter once a month.

How often should the DAC be serviced?

The unit requires a service every 3000 cycles or Bi-annually. The DAC will inform you when a maintenance call is due.

How often should the DAC be validated?

HTM requires all decontamination equipment to be validated on an annual basis.

Cleaning and maintenance

After every 50 runs the DAC Universal will, for 2 seconds, give an acoustic alarm and the display will show the following information: “Remember Check & Clean – Press safety ring” - this to remind the user of the need to clean and maintain the unit.

Below please find the detailed service/maintenance schedule for the DAC UNIVERSAL.

In the table it is indicated how often cleaning/maintenance should be carried out.

If you follow the schedule below, you will ensure optimal maintenance and performance of your DAC UNIVERSAL.
