Which of the following is a potential cause for an electric steamer to not heat properly?

A faulty heating element is indeed a potential cause for an electric steamer to not heat properly. The heating element is responsible for converting electrical energy into heat, which is essential for generating steam. If the heating element is damaged, burned out, or malfunctioning, it will not be able to produce the necessary heat to raise the water temperature, leading to inadequate steaming performance.

In a professional kitchen, ensuring that heating elements are functioning correctly is crucial for maintaining food safety and quality, as improper heating can result in undercooked foods. Regular maintenance and inspection of heating components help prevent issues related to heating failures.
