Abstract

A dishwasher with a system for filling level recognition may be achieved which reliably determines the fluid level inside the dishwasher without the use of moving parts, whereby the dishwasher is provided with at least one capacitive filling level sensor for recognition of the fluid level of the rinsing fluid contained in the dishwasher, the electrical capacitance of which changes depending on the height of the fluid level. The fluid level in the dishwasher can thus be reliably determined without the need for moving parts and merely by the use of electronic components. The system further permits a non-contact filling level recognition, whereby the filling level sensor and the rinsing fluid do not come into contact.
