Steam escapes from the cell
The output conduit of the vapors from the cell must remain free so that the suction due to the
fan of the filters group maintains the cell in slight depression. In this way, the vapors can not
get out of the cell by any other way except through the filter group.
If during the cycle the depression fails, a leak of vapours from the seal of the cell may occur.
It is possible that excessive dust has clogged the circular filter on the lid; in this case it is
necessary to open the cell and thoroughly clean the filter and then check that the vapor
suction hole is not blocked.
Fig. 82
If even after this intervention the steam continues to exit from the cell, put the machine in
"Manual" mode and turn on the vacuum cleaner filters in the group, cut a strip of paper 4 cm
wide and 20 long and bring it close to the vapour suction hole holding it tightly ; if the
paper is not sucked into the tube it is sure thar the columns of lowering temperatures are too
clogged with limestone. In this case the intervention of specialized technicians is required ,
please contact support.
