How Electric Heating Elements Work

When the dishwasher enters the heating phase of the wash cycle, the electric heating element receives power from the control board or timer.

As the element heats up, it warms the water and helps the dishes dry efficiently.

Pros And Cons Of Electric Heating Elements


  • Efficient at heating water and drying dishes
  • Reliable performance with proper maintenance
  • Compatible with most dishwashing detergents


  • May consume more energy compared to other types of heating elements
  • Prone to damage from hard water deposits and mineral buildup
  • Can be more expensive to replace if they malfunction

Heating Coil Vs. Heating Element

While the terms “heating coil” and “heating element” are often used interchangeably, they refer to slightly different components in a dishwasher.

A heating coil refers to a specific shape or form of a heating element, typically found in older dishwasher models.

Other Heating Element Variants

In addition to electric heating elements, some dishwashers may utilize alternative heating elements, such as induction or gas elements.

These variants offer unique benefits and considerations, catering to specific user preferences and energy sources.

Energy Efficiency And Heating Elements

Heating elements in dishwashers play a crucial role in energy efficiency.

Understanding the impact of these elements on energy consumption is vital for making informed decisions when purchasing or using a dishwasher.
