Note
The diaphragm in the valve is broken if the solenoid valve continuously beats in the air.
The diaphragm must be exchanged.
If the solenoid valve does not open, i.e. does not admit any air into cleaning system, check the

If it is clogged, blow it out and bring a refit diaphragm into the solenoid valve.
In the case that the valve still does not release the opening, change the coil (pos. 7).
