REPlAcEMENT OF THE
lEvEl GAuGE
Water inside the heater is kept at a constant level
through the use of a level probe.
This probe is connected to the electronic unit,
which continuously checks water level.
Being always exposed to high temperatures and
steam/water it is subject to encrustations which
can inhibit operations.
WHEN TO INTERVENE
• In case it is verified that there are no prob -
lems upstream from the probe you can easily
access the component and perform careful
cleaning with abrasive or descaling agents.
• Make sure the Teflon coating of the probe is
not damaged. In case of damage, steam leaks
occur and it is necessary to replace the probe.
To remove the probe, simply disconnect the red
wire “A” and unscrew the locking bolt “B” with a
16 mm wrench.
NOTE
When replacing the probe it is necessary to
cover the threads with Teflon tape or liquid
sealant .
