The two flahing lights are normal if the freezer is warm. It will display temperature when it gets cold. If it doesn't get cold there is another problem.
SOURCE: the freezer keeps defrosting
The evaporator coil behind the cover on the back
wall inside the freezer will ice up under normal conditions. Every 8 to 10
hours for around 20 minutes the defrost timer (or in most newer models the electronic
adaptive defrost control) will turn the defrost heater on to
melt the built up ice. There is a defrost thermostat which prevents the heater from
overheating the freezer by breaking the heater circuit when the temp reaches
close to 32 degrees F. The entire cooling system shuts off during the defrost
cycle and starts back when the timer advances through the cycle.
If this ice is not melted it will continue to
build up until the air can’t flow over the coil to circulate the cold air
through the freezer and into the fridge. The temperature change in the fridge
is usually noticed first followed by the freezer.
If the defrost thermostat is bad it can prevent the heater from
coming on OR it won’t turn the heater off when it gets too warm. It is clamped
to the evaporator coil at the top to sense the temp. If it appears to be
misshapen it is bad.
With an ohm meter it should show continuity when
cold and none when warm.
You can also bypass the thermostat to see if the
heater comes on then. If it does then you know the thermostat is bad and needs
replaced.
The defrost heater is
located on the evaporator. It is in a tube which is at the bottom and can also
go up the sides of the evaporator. On some types you can see a burnt spot if
it’s bad. With an ohm meter it should show continuity from end to end when
disconnected from the wiring in the freezer. You can also test the wiring for
voltage when it’s in the defrost mode.
If
you have a defrost
timer you
can test it. It can be located under the fridge behind the kick panel on the
front. Some are in the fridge with the controls at the top. You can turn the defrost timer till it clicks and everything shuts
down. The heater should now come on. If it does, replace the timer because that
means the timer is not running. If it
doesn't, check the heater and defrost thermostat. Turn the timer again till
everything starts back up to end the defrost cycle.
If you have an adaptive defrost control instead of a timer,
replace it if the heater and thermostat test good. It is located in the fridge
with the controls in some models and on the back in others.

You may need a man. Mine was doing the same, The sensor repair kit costs £35 the labour £60, both plus vat, so that was £109.25 in 2009.
Repair men seem thin on the ground and therefore his traveling time may add up. I believe, repair men pay for a course, and then charge like a wounded bull as they are the only ones that can do anything necessary

Hi, activating SuperFrost? 2. Does the door close properly? 3. Is the appliance sufficiently well ventilated? 4. Clear ventilation grilles if necessary. 5. Is the ambient temperature too hot? 6. Has the appliance been opened too often or left open too long? If you want to have a go yourself you will need to find a service manual. There are quite a few things that could cause the fault you have.
I'm pretty sure that the unit has a fault that will need to be looked at professionally but can you discount the following:
1. Have you put too much fresh food into the freezer without

These are quite complicated devices, and many things could be affecting the temperature. Superfrost lowers the freezer temperature to -26 deg, and that could be failing, or you could have a sensor or thermostat problem.
Put a thermometer in the refrigerator, just to check the thermostat reading- also check the freezer side. That will give you a hint if the thermostat is bad.
I would contact Liebherr support, to see what they think, or can do for you. Consult the literature that came with your unit.
Good luck, and hope this helps.
