FIRST INSTALLATION.
The service boiler has not completed the filling
within the maximum time (255 seconds).
The level probe does not detect the presence of
water.
IN OPERATION.
The service boiler has not completed the filling
within the maximum time (90 seconds).
The water in the service boiler has dropped below the
minimum level.
The service boiler has not reached the filling pressure
within the maximum time (60 seconds).
The volumetric dosing device does not perform water
count.
SOLUTION
Check for proper connection of the autosteamer probe and
replace it if necessary.
Check steam boiler heating circuit and replace burned compo-
nents if necessary.
Check heating circuit group : Group heating element; Safety
thermostat, related fuse and triac in the control unit; main
switch; phase connection for 380 V version.
if necessary replace the defective components.
