Excessive air pres-
sure in duct has impact
on water in steam cyl-
inder via steam hose.
Water is pressed into
drainage
•
Reduce air pressure
•
Solenoid valve clos-
ing action imperfect.
Cylinder water level
rises though solenoid
valve is not energised
•
Check solenoid valve
•
Solenoid valve is per-
manently energised
(water intake stops
when unit is switched
off)
•
Relay on main PCB
stuck. Measure volt-
age across terminal 11
and N. Replace PCB,
if required
•
Large amounts of
residues influence or
restrict cyclic blow-
down. The additional
water introduction
caused by the optional
SuperFlush rinse
device may cause the
max. level fault
•
Clean steam cylin-
