Did I ever warn you about scale?

An ECM Giotto came in with a pretty serious scale issue. The result was several leaks in various fittings, shorted out solenoid coil & needed replacement of the vacuum valve and safety valve. The E61 was also obstructed by calcium build up (see the valve body soaking in solution).

The frame had a fair amount of rust though still able to hold the unit together.

Most or maybe all of this repair would not be needed if proper descale procedure or filtered water was used.
