What to do if the door of my W&H Med Lisa VA131-22 Laboratory Equipment won't open?
If your W&H Med Laboratory Equipment displays 'Open the door' at the end of the cycle, but you cannot open it, switch the sterilizer off to release any internal pressures. If the problem continues, contact technical service. Also, the bacteriological filter may be blocked; remove it to release the pressure and then replace the filter.
What to do if W&H Med Lisa VA131-22 Laboratory Equipment display reads “Open the door” but opening the door is impossible?
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.
