Tecnical Features
Security Systems
•Flowmeter:
The amount of water intake is in precise control.
•Heater safety protection:
In case of lack of water, with the help of a pressure switch, the resistance is prevented from
being in operation. So both the resistance and the machine itself are protected.
•Overflow and Leakage Protection:
The dishwasher enters overflow mode when there is too much water in the dishwasher, the
excess water gets drained. (a floater rises upwards and senses when overflow water gets
there)
It also detects leaks in the base of the dishwasher, shuts down operation and automatically
pumps out water before contact with floor.
Resettable overflow
