A5 CLEANING, CHECKING AND REPLACING THE SOLENOID
VALVE
A solenoid valve is a mechanical opening and closing device actuated by means of a solenoid.
It regulates or stops the flow of water to the head brushes. It is powered at 36 V DC directly
from the control panel, which also controls it simultaneously with operation of the brushes,
either manually or through three programs, P1, P2 and P3.
The operating principle of the solenoid valve involves a current which, when activated, passes
through a solenoid A creating a magnetic field which attracts the iron core B in the port inside
the solenoid upwards, bringing with it the membrane C which frees the normally closed port,
allowing the solution to flow out.
The solenoid valve consists of a plastic body D, a solenoid A, a tightening nut E, an iron core B
and a cap F to enable the port to be cleaned.
It is connected electrically by means of two opposite connections G.
