![]() ![]() Each element has its own voltage rating, and any voltage above the required will burn the element. Power SurgeĪn element can also get burnt as a result of a sudden increase in voltage caused by a power surge or lightning. Whenever the temperature exceeds normal, the high limit switch on the thermostat is triggered, and the power will be shut down.Ī malfunctioning thermostat will fail to control the heat supplied to the water heater element, which eventually causes it to burn. The function of a thermostat is to tell the elements when to heat the water concerning different temperature levels. This can cause a failure of the water heater. ![]() If this is not done, the trapped air ‘Air Pockets’ will make the upper element to burn as it isn’t immersed in water. There is a need to bleed a line on the water to extract trapped air and sediments in the tank either once or twice a year. The heat generated by an element can burn through its copper if not transferred to the water. ![]() Trapped Air PocketsĪll water heater elements must be operated immersed in water.

Here are some of the possible reasons why your water heater element stopped working: a). These are some of the tools you should have handy before you commence your water heater element testing:Ĭauses of Failure of Water Heater Element In this article, we will show you step-by-step DIY guides on testing water elements with the use of a digital multimeter with no professional background in electrical works.
