Self cleaning solenoid valves
Self Cleaning solenoid valves have the most simple working principle. The flow passes through a small orifice
that can be closed off by a plunger with a rubber gasket on the bottom. A small spring holds the plunger
down to close the valve. The plunger is made of a ferromagnetic material. An electric coil is positioned
around the plunger. As soon as the coil is electrically energized, a magnetic field is created which pulls the
plunger up towards the center of the coil. This opens the orifice so that the medium can flow through.
Keep in mind that whenever you change a new washing circuit with Self Cleaning solenoid valves select
the correct number of rotors in Service Menu>Washing>Number of Rotors according to the serial number
and select the washing valve type. To ensure that the oven runs the correct washing program in terms of
durations and consumptions.
