How to Troubleshoot & Repair Sterilizers

Nina Nixon

Sometimes sterilizers fail to work properly due to incorrect water levels or cycle timing frequency. If water levels are too low, the cycle may take longer than required. If water levels are too high, the sterilizer may beep to alert you that something is wrong. The machine can also overheat if cycles run too close together. To run efficiently, it needs a chance to cool down before it cycles again. It is also important that the connection to the electrical power source is not interrupted. If you use an extension cord, it must have enough current to power the machine.

  1. Make sure that the sterilizer is operating for efficiency and longevity. Allow it to cool down for 10 to 15 minutes between cycles so that it does not overheat.

  2. Check that items are placed face down so that the steam can access all areas of the items being steamed. Use the lid during each sterilizing cycle to seal the steam in. Taking these actions should resolve sterilization issues.

  3. Check how the sterilizer is connected to the electrical power source. Extension cords vary by electrical ratings and, if you use one, its rating should be equal to or greater than the sterilizer's rating to power the appliance.

  4. Fill the sterilizer to moderate or full capacity. Small loads will take the steamer longer to complete.

  5. Check the water level if the sterilizer makes beeping noises. If there is not enough or too much water, replace it with 90 ml of water for the first cycle or mode; use 200 ml of water for the second cycle or mode.
