Max.-level (only HKDB)
Water level has reached its
maximum 5x in one single
steam production phase.
•
Excessive air pres-
sure in duct has impact
on water in steam cyl-
inder via steam hose.
Water is pressed into
drainage
•
Reduce air pres-
sure, check steam
hose for blockages
•
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 contacts on
mainboard stick. Mea-
sure voltage across
terminal 11 and N;
replace mainboard, if
required
•
Large amounts of
residues influence or
restrict cyclic blow-
down. The additional
water introduction
caused by the optional
HyFlush rinse device
may cause the max.
level fault
•
Clean steam cylin-
der, cylinder base,
water sensor tubing
and drainage system
