Drip stop
The drip stop function prevents expanding water from drip-
ping from the tap during heat up. Any drips formed can leave
the tap as residual water.
Pressure stop
The appliance features pressure switch off.
The pressure switch off indicates when the tap is clogged by
limescale (low or no flow).
When water pressure exceeds 0.25 Mpa (2.5 bar) it even
detects if the appliance has been incorrectly connected with
the water line during initial installation.
The pressure switch off automatically shuts off the water
inlet and prevents rupturing of the tank.
It the pressure stop has tripped, a red pin will appear at the
top of the appliance (C1).
The fault must be corrected (see chapter “A fault, ■
what to do?”).
After the fault has been corrected, the red pin can be ■
pushed back in easily (C2). The water inlet is now free.
Please contact customer service if this occurs repeatedly. ■
Important: Do not block the path of the pin (C1) with
objects.

Clean appliance externally with a mild cleaning agent. ■
Clean the dirt and lime scale deposits in the aerator filter. ■
Descaling
Descale the outlet pipe with commercially available des- ■
caling agent or vinegar.
Please observe the manufacturers warnings when ■
descaling.
If the water flows significantly slower when the tap is fully
opened, the small water heater and tap should be descaled
by a specialist. Otherwise, the pressure stop may trip due to
an unpermissible high pressure.
