Dishwasher power usage

Dishwasher power is often confused with energy consumption. In fact, these are two different concepts, and knowing both is fundamentally important.

Dishwasher power is a value in watts, expressing the rate of energy conversion of the system per unit of time. It is measured in watts (W). Simply put, power determines how efficiently, how fast, and at what power the technique is capable of working.

If the power usage of the system is not enough to run the dishwasher, the appliances will not work properly and in some cases, it is a fire hazard. Theoretically, the more powerful the dishwasher, the more power it consumes. You can also find out more information about this topic.
