Unit / s with series error, service underground

Cooling equipment of the brand Liebherr rushes you know, the call requires that they belong to the best quality.
The is in the case of KTP 1554 unfortunately not so. The 4 star refrigerator compartment makes frozen food labbe engined biowaste and at USN since the purchase in early November of 2010.

The device has been "repaired" after several days of temperature measurement and since it has not cooled properly, then replaced.
But even the exchanged device displays the same error.
Our refrigerator is incidentally quite correct in a normal heated / ventilated room and can dissipate the heat over a grid in the countertop, so nothing unusual.

Unfortunately spoiled food is also reflected in the Service Liebherr stubborn German unkulant and rejects regarding a concession. Outright.
We will now convert the unit and refrigerator made in the Eastern Bloc to buy, which is much cheaper to boot.
The money saved will be put aside and then just a little more set us a new device.
This saves us time and money, but get angry about the fact that our money any more German companies benefit.
