Fault Max.-Level
ctd.
• Solenoid valve does not close properly. Water
level in the cylinder rises slowly even though
the solenoid valve has not been activated.
• Check solenoid valve.
• Water is supplied even thoough the steam
humidifier is switched off. Solenoid valve
remains open.
• Clean solenoid valve.
• Inlet solenoid valve is receiving a constant
electric signal. (If the unit is turned off, water
feeding stops.)
• The relay on the main PCB has
stuck. Measure voltage at PBC-
terminal 10 against N.
• Large amounts of deposits are interfering with
and disrupting the blow-down cycle. Due to
extra water entering the flushing mechanism,
the max.-level is reached during the blow-
down process.
• Clean humidifier, drain assembly
and hose to the control cylinder.

• Solenoid valve or feed line is fouled or defec-
tive.
• Clean or replace solenoid valve or
feed line.
• Defective coil. • Measure coil and replace.
• Water supply is not open. • Open water supply.
• Solenoid valve has not been electrically
activated.
- The cable connections are faulty.
- The relay on the main PCB is not operating.

• The steam hose has not been laid at enough
of an incline, causing a water pocket to form.
The steam flow is obstructed.
• Check placement of steam hose.
Remove water pocket.
