1. Check limit set for b6
2. Turn the machine off and
clean the water conductivity
probes
3. If the problem persists,
change the source of supply
water or install a suitable
treatment system
(demineralization, even
partial).
Note: the problem will not be

Lack of water
1. Check that the fill pipe from
the main to the humidifier and
the internal pipe are not
blocked or bent and that there
is sufficient pressure (0.1-0.8
mpa, 1-8 bar)
2. Check the operation of the
fill valve
3. Check that the steam outlet
is not working against
excessive back-pressure,
preventing the flow of water
into the cylinder by gravity
4. Check that the steam outlet
pipe is not is kinked and that
there are no sags.
