Electric water distiller is a kind of device that produces purified water by heating tap water. It works by heating water to generate steam, which is then condensed back into distilled water. Such equipment is widely used in sectors including pharmaceuticals, medicine preparation, and various types of laboratories and testing facilities.

As a water distiller is used over time, a thick layer of scale will form on the surface of the electric heating element. This hinders the transfer of heat, reduces energy efficiency, and leads to a gradual decrease in the output of distilled water. In such cases, the scale can be removed using either physical or chemical methods. If there is a significant drop in water output, it is likely that a heating element has burned out, resulting in a loss of power and, consequently, reduced output. You can use a multimeter—while the unit is powered off—to identify and replace any faulty heating elements. After replacement, fill the unit with water to check for leaks or seepage; only once you have confirmed there are no leaks should you reconnect the power and resume operation.
