RESET THE SAFETY THERMOSTAT

The sterilizer is fitted with a safety thermostat to prevent it from overheating. If the safety thermostat operates because of too high
temperatures, the error 240 or a timeout error is displayed. The thermostat must be reset manually. Proceed as follows:

1

Wait for the sterilizer to finish the error reset phase and follow the instructions on
the display.

2

Switch the sterilizer OFF and remove the mains cable.

3

Wait for the sterilizer to cool down.

4

Open the sterilizer door.

5

Unscrew the cap and push on the reset button of the thermostat switch.

6

A click sound indicates that the thermostat switch has been reset.

7

Screw the cap.

8

Connect the mains cable and switch the sterilizer ON.

Note: If the thermostat operates repeatedly, call technical service.
