Bosch KDF3295/05_FD7911 temperature problem

Its start and works ok for approx 12 hours and after that is activate alarm and shows ER on display. First of all I need to say it was coming with capillary tube from valves disconnected. I had one similar fridge at work and I’ve connected valves in same way (KSF3200/05_7803). Now both fridges have same faults. I have tried to change electronics between them selves and have same results.

Please if you can help with directions or manual is better. (perhaps valves are not in correct connection, sensors out of order?)

Thanks’ Baron
