FIELD: personal use articles.
SUBSTANCE: dishwashing machine comprises a washing tank (10) with a tray (12), at least one spray nozzle installed inside the washing tank, a facility for fresh water supply into the tray, a circulating pump (14) for process water supply from the tray (12) to the spray nozzle and a sensor of electroconductivity (24) to measure electroconductivity of fresh and/or process water. To make it possible to use a single sensor of electroconductivity for measurement of electroconductivity of both fresh and process water, the electroconductivity sensor (24) is installed in the fresh water supply pipeline for supply into the tray (12), and additionally there is a bypass pipeline (34), which provides process water flow through the sensor (24) of electroconductivity during operation of the circulation pump (14).
EFFECT: simplified design of dishwashing machine, possibility to measure electroconductivity of both fresh and process water.
