Replace all solenoid valves

replace them every 5 years. The electrical coil outside, and spring and Viton sealing inside the valve
are prone to wear and tear.
Replacement of the solenoid valves requires that the water mains is disconnected, pressure in the
boiler and heat exchangers is relieved, the machine is shut off, and preferably cooled down.
