5. Troubleshooting
Observe chapter „Recalibrating the sensor“ to restore the factory
settings.
Problem Cause Remedy
Water does not run. The sensor does not rec-
ognise black objects.
Select an object with a
different colour.
The sensor is flashing.
The sensor is dirty.
Clean the sensor (see
chapter "Cleaning and
care").
Reflection in the wash-
basin.
Remove the object or
carry out recalibration.
Short spray of water at
the tap outlet.
The power supply is in-
sufficient.
Restore the power supply
or replace the battery.
The sensor is dirty. Clean the sensor.
The tap switches inde-
pendently.
Reflections in the wash-
basin trigger the flow of
water.
Recalibrate the sensor.
The water flow is too low. The aerator is blocked. Clean/replace the aer-
ator.
The tap switches off.
An object is within range
of the sensor for approx.
90seconds without
moving.
The tap automatically re-
calibrates the sensor.
If you cannot remedy the fault, notify your qualified contractor.
To facilitate and speed up your enquiry, please provide the serial
number from the type plate on the cold water supply (000000-
0000).
5.1 Recalibrating the sensor
Your settings will remain unchanged after recalibration. The sen-
sor is automatically recalibrated to the washbasin.

Touch the touch area for 2sec-
onds. The green LED lights up

prox. 5 seconds until the LED
has flashed red four times. Do
not reach into the sensor area.

Note
The sensor tap is powered by a lithium battery.
Remove spent batteries. Leaking batteries cause damage
which is excluded from any warranty. Non-rechargeable
batteries must not be recharged.
Never use rechargeable batteries.
If the sensor tap is not going to be used for an extended
period, remove the battery.
Battery disposal
Never dispose of batteries with domestic waste. Spent
batteries may contain noxious substances that can be det-
rimental to the environment and human health. Dispose
of batteries through your dealer or via a central recycling
point for special waste.
5.3 Supplement “Touch settings and
programming” on the internet
Note
You can also find separate instructions for
"Touch settings and programming" for the
sensor tap on the internet. To view this,
scan the QR code or paste this link into
your browser: www.stiebel-eltron.de/
sensorarmaturen
We recommend that you:
Print out the instructions and laminate them.
Position the instructions close to the sensor tap.
6. Cleaning, care and maintenance
Never use abrasive or corrosive cleaning agents or abrasive
sponges.
If the sensor tap is dirty or covered in limescale, clean it with
soapy water or diluted domestic vinegar, then rinse with
plenty of clean water. Dry the sensor tap with a cloth.
For descaling, remove the aerator from the fitting. To avoid
inadvertently triggering the flow of water, activate a draw-off
pause; see chapter „Extended settings/ Setting the draw-off
pause/ Activating the draw-off pause“.
