  Carol SuttonSep 4, 2025
  If, at the end of the cycle, the display reads “Open the door” but opening the door is impossible: * Switch the sterilizer OFF: this releases any internal pressures allowing the chamber door to be opened, if the chamber is in vacuum due to an internal malfunction. Call technical service if the problem persists. * Remove the bacteriological filter to get the pressure released and replace the filter, if the bacteriological filter is blocked. Note: The bacteriological filters need to be replaced every 400 cycles.
