5.6 THE LEVEL PROBE
The water inside the steam boiler is main-
tained at a constant level through the use of
a level probe inserted inside the boiler. This
probe is connected to the electronic control
unit that continuously polls the probe.
Being always exposed to high temperatures
and steam/water it is subject to encrusta-
tions which can inhibit operations.
WHEN TO INTERVENE
In case it is verified that there are no
problems upstream from the probe you
can easily access the component and
perform careful cleaning with abrasive or
descaling agents.
Make sure that the Teflon coating of the
probe is not damaged. If it is, there would
be a loss of steam and electric insulation
and the probe should be replaced.
TO REMOVE THE PROBE
Simply disconnect the red wire.
Utilizing a 17 mm cup hex wrench, un-
screw the probe from its housing.
