Maintenance and care

4.3.2 Emergency mode

If the appliance is faulty, you can use the emergency mode to
activate the electric emergency/booster heater.
The compressor shuts down if, following a DHW demand, no tem-
perature increase is captured for 13 hours (52 intervals of 15 min-
utes each, during which the temperature increase is <0.25 °C re-
spectively). The "service/fault" symbol flashes on the display and
a fault code indicates that the appliance is not heating.
In this case you can activate emergency mode by pressing the
"Quick heat-up" key. After the "Quick heat-up" key has been
pressed, the indicated fault code increments by a value of 256,
as the fault codes are added together (see fault code table in
the "Troubleshooting" chapter). "Service/fault" symbol continues
flashing. The electric emergency/booster heater is activated.
The current set temperature (set temperature 1 or set tempera-
ture 2) is ignored. In emergency mode, the appliance operates
with a fixed set temperature of 40 °C. Following one-time enabling
of this function by means of the "Quick heat-up" key, this function
remains enabled for 7 days.
Following 7 days of emergency operation the electric emergency/
booster heater is disabled. The fault code shown on the display
decrements by 256.
If you press "Rapid heat-up" again within the 7 days of emergency
heating mode, the 7-day runtime for emergency heating mode
will restart.
If the 7-day runtime for emergency heating mode has expired,
you can restart emergency heating mode for a further 7 days by
pressing "Rapid heat-up".
Pressing the "Quick heat-up" key only enables emergency mode if
an error with fault code 8 occurred previously. In standard mode
pressing the "Quick heat-up" key only triggers one-time heat-up
of the DHW cylinder.
Emergency mode is disabled by an interruption of the power sup-
ply. The appliance tries again to heat with the heat pump. Fault
code 8 is only set after 13 hours. Only then can emergency mode
be manually re-enabled via the "Quick heat-up" key.

f Interrupt the power supply by unplugging the appliance from f
the mains or by tripping the MCB.
f Shut off the cold water supply. f

Maintenance work, such as checking electrical safety,
must only be carried out by a qualified contractor.
Appliance Care and maintenance tips
components
Casing Use a damp cloth to clean the casing sections. Never use
abrasive or corrosive cleaning agents.
Air intake Clean the air intake grille and air discharge grille every six
grille / air dis- months. Cobwebs or other kinds of contamination can re-
charge grille strict the air supply to the appliance.
DHW cylinder The DHW cylinder is equipped with a maintenance-free im-
pressed current anode to safeguard it against corrosion. The
power supply must not be interrupted while the appliance is
filled with water to enable the impressed current anode to
provide protection. Otherwise there is a risk of corrosion.
Electric emer- Have the electric emergency/booster heater descaled from
gency/booster time to time. This will extend the service life of the electric
heater emergency/booster heater.
Appliance Have the safety assembly and the evaporator checked regu-
larly by a qualified contractor.
Condensate Undo the condensate drain. Check that the condensate drain
drain is clear and remove any dirt from the condensate drain
connection.
Scaling
Almost every type of water will deposit limescale at high tem-
peratures. This settles inside the appliance and affects both the
performance and service life. A qualified contractor who knows
the local water quality will tell you when the next service is due.
f Check the taps regularly. Limescale deposits at the tap out- f
lets can be removed using commercially available descaling
agents.
f Regularly activate the safety valve to prevent it from becom- f
ing blocked, e.g. by limescale deposits.
