3.14 – If steam delivery is requested, the pressure switch shows zero
pressure and the steam delivery stops immediately.
Possible reasons:
1 - Electronic station faulty.
2 - The solenoid valve (e3) (fig.48) stays in its locked open position, and
water flows out into the steam tank. (Due to this problem, the steam boiler
could get completely full, considerably reducing thus the area for the
steam).
3 – Anti-depression valve locked closed (this reason is valid only for the
first steam delivery request).
