What is a calrod in dishwasher?

A *calrod* is a heating element used in dishwashers and other appliances. It consists of a metal tube that is filled with a resistive material. When an electrical current is passed through the tube, the resistive material heats up and transfers heat to the surrounding area.

Calrods are typically made of nickel-chromium alloy, which has a high resistance to electricity and a low coefficient of thermal expansion. This means that the calrod can withstand high temperatures without becoming damaged or deformed.

Calrods are used in dishwashers to heat the water that is used to clean the dishes. The heated water helps to dissolve grease and food particles, making it easier for the dishwasher to remove them.

In addition to dishwashers, calrods are also used in other appliances such as ovens, ranges, and toasters.
