The dishwasher heating element helps in drying the dishes after they have been washed. As the air inside the dishwasher is heated, the dishes are dried. Over time, the heating element in a dishwasher may become worn out or damaged due to regular use. If your dishes are not drying properly or are producing a burning smell, it's time for a dishwasher heating element replacement. https://partsfe.com/dishwasher-parts/heating-element
