3.7 – During the steam boiler water level renewal phase, the pump
goes on working for a maximum time of 2 minutes, leading to
safety stopping of the machine.
Possible reasons:
The solenoid valve (e3) stays in its locked closed position and the water,
instead of flowing into the steam boiler, overcomes the restriction of the by
pass (c1) and flows into the water tank.
Operations:
Clean the solenoid valve (e3) if dirty, or replace it if faulty (see fig.28).
