14.1 Fault codes

fault description
2 perma- The sensor at the cylinder top
nently is faulty. The actual temper-
on ature display switches from
the cylinder top sensor to the
integral sensor. The appliance
continues to heat without any
loss of comfort. The mixed
water volume cannot be
calculated and is displayed
as "- -".
4 perma- The integral sensor is faulty.
nently In the event of a faulty in-
on tegral sensor, the integral
sensor is set to the value of
the sensor at the cylinder top,
and amount of mixed water
is calculated using this value.
The appliance continues to
heat with a reduced start
hysteresis.
A mixed water volume is
still calculated, based on the
assumption that the cylinder
top temperature is reached
throughout the DHW cylinder.
6 flashing The sensor at the cylinder
top and the integral sensor
are faulty. The appliance no
longer delivers heat.
8 flashing The appliance has ascer-
tained that the DHW cylinder
has not been heated within
the maximum temperature
increase time, despite there
being a demand.

remedy
Check that the plug is seated
correctly.
Measure the resistance of the
sensor and compare it with the
resistance table.
Install the replacement sensor.
Check that the plug is seated
correctly.
Measure the resistance of the
sensor and compare it with the
resistance table.
Install the replacement sensor.
In the service menu, use param-
eter "IE" to switch to standby
mode.
Check that the plug is seated
correctly.
Measure the resistances of the
sensor and compare them with
the resistance table.
Install the replacement sensor.
In the service menu, use param-
eter "IE" to switch to standby
mode.
Check if a DHW circulation line
is installed and whether it is
insulated. The total power loss is
greater than the heating output
of the appliance.
Check if a DHW circulation pump
is installed and whether it is
controlled according to temper-
ature or time. If required, install
a corresponding control unit.
Check the refrigerant circuit for
leaks.
fault description
16 perma- A short circuit of the im-
nently pressed current anode has
on occurred or the protective
anode is faulty.
32 flashing The appliance is being op-
erated with a partially filled
DHW cylinder. The appliance
does not heat up.
The anode current is inter-
rupted. The appliance does
not heat up.
64 perma- The defrost temperature has
nently not yet been reached after
on the maximum defrost time
has lapsed. The compressor
is faulty.
The temperature of the intake
air is below the lower appli-
cation limit.
128 perma- There is no communication
nently between the controller and
on the programming unit. The
most recently selected set
values are active. The ap-
pliance continues to deliver
heat.
256 flashing Manually activated emer-
gency mode (only electric
emergency/booster heater
enabled)
E 2 flashing The temperature sensor on
the evaporator is faulty.
E 16 perma- The high pressure limiter
nently has responded. Compressor
on heating mode is temporarily
blocked. Compressor heating
mode will continue as soon as
the pressure has normalised.
E 32 perma- An electrical fault has oc-
nently curred.

remedy
Check the cables and relevant
plug-in connections of the im-
pressed current anode according
to the connection diagram and
replace faulty cables.
Check the impressed current
anode in the heating element/
anode assembly and replace if
required.
Fill the appliance's DHW cylin-
der. The fault code disappears
and the appliance starts.
Check the contacts of the im-
pressed current anode.
Check the position of the evapo-
rator sensor in the evaporator.
Wait for higher ambient temper-
atures. Ensure that values do not
fall below the application limit.
Check that the plug is seated
correctly, and if required, re-
place the connecting cable.
Replace the programming unit
PCB.
See chapter "Appliance descrip-
tion / Emergency mode".
Check that the plug is seated
correctly.
Measure the resistance of the
sensor and compare it with the
resistance table.
Replace the sensor.
No action required.
After consultation with the cus-
tomer, reduce the set temper-
ature if required. Increase the
charge level with the program-
ming unit.
Check the offset of the integral
sensor to the cylinder top sensor
and adjust if required.
Check the high pressure switch-
ing point and replace the high
pressure switch if required.
A1/X2 : Check whether the power
supply has been interrupted.
Then reset the fault with the
corresponding menu option.
