5.4 REPLACEMENT OF THE
LEVEL GAUGE
The water inside the heater is maintained at a
constant level through the use of a level probe
inserted inside the heater.
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 encrustations which
can inhibit operations.

is not damaged. If it is, there would be a loss
of steam and the probe should be replaced.
To remove the probe simply disconnect the red
wire and unscrew the bolt with a 17 mm wrench.
NOTE
When replacing the probe it is necessary to
cover the threads with Teflon tape or liquid
sealant.
