Brewing stops mid cycle

Sounds like dosage is too high and grind is too fine.

Rule of thumb with any saeco unit.

Do not grind any finer then 2 or your looking for trouble.

Open grinder, clean it out with a vac. Slapped it back on.

The reason it stops is grind is too fine, and the machine doesn't have enough pressure to pass threw the grinds, creates back pressure in the machine and the unit failsafes after a certain amount of time with and pressure.

Back pressure is what blew your boiler.
