The boiler has been completely overhauled and solenoid valve clean, vibratory pump has been checked to be completely in working order and all the inlet water piping from water reservoir to the pump and from the pump to the inlet of the boiler has been checked to have no scale and clog. The outlet from the boiler to the 3 way solenoid valve has been checked to have no scale built up.
The group shower screen has been clean completely to 99% new.
After checking all, ther water dispensing from group is still very restricted.
Suspecting that the magnetic solenoid valve is not working. Could this have caused the slow to almost no dispensing of water when the brew button is engaged?
