What is the most common cause of sterilizer overheating in units with electric steam generators?

The most common cause of sterilizer overheating in units with electric steam generators is mineral buildup or scale formation on the heating elements. When water is heated, minerals such as calcium and magnesium can precipitate out of the water and deposit onto the heating elements. This scale acts as an insulator, reducing the efficiency of heat transfer from the heating elements to the water. As a result, the heating elements must work harder to generate the required steam, leading to increased element temperature and potential overheating. In severe cases, the heating elements can overheat to the point of failure. Regularly descaling the steam generator is essential to prevent mineral buildup and ensure efficient and safe operation.
