inlet valve will open automatically once the system
reaches maximum level. If water level is still lower than the
minimum water level 10 minutes after, it indicates faults of the

Auto heating up by sections: generator will compare the
measured room temperature with the setting temperature and
Auto water supplementing: if the water level is lower than
the desired level when operating, auto water supplementing
function will be on and open the inlet valve. Once the water
level reaches the desired level, auto water supplementing

the pipe line regularly according to the local water quality and
usage of the steam generator.
and remove the element access cover when the generator
completely cools down. Label the wires connect to the heating
elements which need to be replaced and plug out the wires.
Screw the heating elements out. Clear the scale in the water

5. Replace the main board:
when the generator completely cools down. Label the three
wires which connect the upper part of the main board to the
water level sensor and the source, drain valve and water inlet
solenoid valve in the bottom part of the main board. Unplug
these wires and remove the main board (be careful with yellow-
green ground wire under the screws of the circuit board). Install

when the generator completely cools down. Unplug all the wires
on the sub-board. Label all the wires on the relay and remove

and water supply. Remove the water inlet, steam outlet and
draining pipelines after the generator completely cools down.
Then please lean the steam generator to remove the base
so that the faulty valve could be removed. Finally please install
the replacing valve carefully.
8. Replace the water level sensor:

of the plastic nut reaches the same height as the old one. Finally
TROUBLESHOOTING
more services or technical helps please contact the dealer.
Model steam generator has self-diagnose function, and some
common faults will be displayed on the screen if occur.
• Code -L
Meaning:
Temperature measured by temperature sensor is below 6°C.
Diagnose and Solution:
should disappear after the room temperature reaches 6°C.
• Code -H
Meaning:
Temperature measured by temperature sensor is higher than
60°C.
Diagnose and Solution:
should disappear after the room temperature drops below 60°C.
Diagnosing procedure:

temperature is more than 2°C above the setting value with
the indicator on, carefully test the relays on the sub-board
and change the faulty ones, or change the whole sub-board.
• Please refer to the circuit and connection diagrams for
diagnosing and repair.
