What to do if the W&H Steriliser door won't open after cycle?
- N
  nicholas14Aug 18, 2025
  If your W&H Steriliser displays 'Open the door' at the end of the cycle but you can't open it, there might be a vacuum in the chamber due to an internal malfunction. In this case, switch the steriliser OFF to release any internal pressure, which should allow the door to open. If the issue continues, contact technical service. Alternatively, the bacteriological filter may be blocked. Remove the bacteriological filter to release the pressure and replace the filter. Remember to replace these filters every 400 cycles.

Why does W&H Steriliser door open immediately after locking?
- A
  Albert KaneAug 21, 2025
  If, when starting a cycle, the chamber door of your W&H Steriliser locks and then immediately re-opens, displaying the message 'Open the door', it could be due to a couple of reasons. First, check that the door seal is correctly and evenly inserted around the entire circumference. A seal that is sticking out can cause this issue. Second, ensure that nothing is obstructing the door, either external objects or the load itself. Remove any obstructions and make sure the door isn't pressing against the load or any of the chamber furniture.

How to prevent corrosion on instruments in W&H Steriliser?
- M
  Marcia GonzalesAug 23, 2025
  If you notice corrosion or spots on instruments after using your W&H Steriliser, several factors could be at play. Ensure instruments are completely dry before placing them in the sterilizer. Avoid using tap water or water of poor quality; instead, use good quality water. Also, make sure instruments are free from organic or chemical residues by cleaning, rinsing, and drying them beforehand. Keep the chamber, trays, and chamber rack clean. Lastly, prevent contact between instruments made of different materials by placing them on separate trays or in pouches.

Why is there water left in my W&H Steriliser after cycle?
- A
  Alice JonesAug 26, 2025
  If, at the end of a cycle, you find residual water in the chamber of your W&H Steriliser, several factors could be the cause. Ensure the sterilizer is properly leveled. Avoid overloading the chamber, and always adhere to the maximum load weight limits for each load type, utilizing the chamber rack for trays and cassettes. Check the chamber filter for clogs and clean it if necessary. Also, verify that the chamber filter cap is correctly positioned. Finally, ensure the load is placed correctly within the chamber.

What to do if W&H Steriliser is leaking water?
- M
  michelle39Aug 27, 2025
  If water is leaking at the front of your W&H Steriliser, it could be due to a leak through the chamber door seal. Try cleaning or replacing the door seal, and also clean the chamber face side. If the leak persists, it might be an internal leak, and you should call technical service.

Why is W&H Steriliser sterilization cycle taking longer?
- A
  Anthony MorganAug 30, 2025
  If the sterilization process phase of a sterilization cycle on your W&H Steriliser was longer than expected, it could be because the chamber temperature dropped below the minimum threshold, and the software successfully recovered. Allow the cycle to complete. However, if this occurs frequently, it's recommended to contact technical service.

Why are my instruments turning brown in W&H Steriliser?
- C
  Christina TannerSep 1, 2025
  If your instruments are turning brown or black after sterilization in the W&H Steriliser, it's likely due to an incorrect temperature selection. Select a sterilization cycle with a lower temperature, and always follow the instrument manufacturer's instructions.

Why does W&H Steriliser go to standby after opening the door?
- S
  Shawn PettySep 3, 2025
  If your W&H Steriliser enters standby mode immediately after you open the chamber door, it's likely because the chamber door wasn't opened after the previous cycle finished, and the standby mode delay has expired. Simply press the standby button to exit standby mode.

Why is there no pressure in my W&H Steriliser?
- K
  Katelyn RussellSep 5, 2025
  If the cycle commences in your W&H Steriliser, but there is no pressure or temperature rise, it could be due to a couple of reasons. First, the thermal overload switch might be open; try resetting it. If the issue persists, there may be an electric or electronic fault, and you should contact technical service.
