flashing
The appliance has ascertained
that the DHW cylinder has not
been heated within the maxi-
mum temperature increase time,
despite there being a demand.
You can temporarily contin-
ue to use the appliance by
pressing the "Rapid heat-
up" key to activate emer-
gency heating mode. See
chapter "Appliance descrip-
tion / Emergency mode".

A short circuit of the impressed
current anode has occurred or
the protective anode is faulty.
Immediately notify a qual-
ified contractor, as the
appliance is not protected
against corrosion if the
impressed current anode
is faulty.

flashing
The appliance is being operated
with a partially filled DHW cyl-
inder. The appliance does not
heat up.
Fill the appliance's DHW
cylinder. The fault code dis-
appears and the appliance
starts.

perma-
nently
on
The defrost temperature has not
yet been reached after the max-
imum defrost time has lapsed.
The compressor is faulty.
The fault is reset automat-
ically once the evaporator
temperature has risen to the
defrost end temperature.
The temperature of the intake air
is below the lower application
limit.
Wait for higher ambient
temperatures. Ensure that
values do not fall below the
application limit.

The high pressure limiter has
responded. Compressor heating
mode is temporarily blocked.
Compressor heating mode will
continue as soon as the pressure
has normalised.
Wait until the pressure has
normalised.
E 32
perma-
nently
on
An electrical fault has occurred.
Notify a qualified contrac-
tor.
E 64 flashing Evaporator temperature < mini-
mum evaporator temperature
Notify a qualified contrac-
tor.
E 128
flashing
A permanent pressure switch
fault has occurred. A pressure
fault occurred multiple times
within a defined pressure fault
evaluation time.
Notify a qualified contrac-
tor.
If several faults occur, the fault codes are added up.
Example: If both the cylinder top sensor and the integral sensor
are faulty, the display shows fault code 6 (= 2+4).
Application scenarios for emergency mode
If the appliance shows fault code 8, you can manually activate
emergency mode. If a different fault occurred previously, but did
not cause the appliance to switch off, the display may show a
fault code that is the result of several faults added together. Listed
below are the fault codes which will allow you to enable emer-
gency mode.
