Water Boiler Nefit Problem OH Code - What to do?

[johanna_W]

Hello

My name is Johanna and I have no hot water and heat since yesterday..maybe someone can help me here :)

The boiler I have is Nefit ProLine (NxT HRC 24/CW3, NxT HRC 24/CW4, NxT HRC 30/CW5 ). I also attached some pictures.
So far, I found out that OH stands for "stand by" but I have not found any instructions how to change that.

If some could guide me through the steps that I have to do - that would be amazing! :)
Or is it not possible to do it by myself and should I get a technician?

Thank you in advance!

you should ad water to the system, the pressure is 0.6 bar this should be ad minimum 1.5 and maximum 2.0 bar.
the point where you can ad water to the system is the valve with the red handle below the gasvalve with the yellow handle, sorry for my English writing.....

One more question: The blue valve should be open right? or do I have to turn it off?

You have to open the blue valve to add water to the system. Once the system has reached the right pressure, close both valves and disconnect the hose between them. (I think voor now you still need to attach the hose to the system, right under the red valve).
