Dishwasher

Belongs to:
Kitchenware and household appliances
Description:

A dishwasher is an electrically driven kitchen device for the automated cleaing of dishes. The alternating electric and magnetic fields at the fundamental frequency of 50 Hz resp. 60 Hz are caused by the motor rotating the rinsing nozzles and the heating process of the rinse water.

Frequency ranges:
  • 50–60 Hz
Type of field:
electric and magnetic
