I am asking for all help because my child will freeze at night! Write pls what information do you still need. What should I check ...

Give me a photo of the pump, if it works, you may need to bleed, i.e. loosen the screw in the middle until the air hisses, it is possible that the pump has stopped, set to 3 gear. , if it is spinning and you have open and the radiators and all valves are probably a check valve behind the pump jammed a frequent cause, then call a plumber and let it change only to one with a metal non-plastic plug, because again clogs can just clogged filters. The easiest way to call the service is.

Have you checked the water pressure in what? It could go down over the summer. Bleed the radiators. See if the room controller is well set.

Thanks. I don't have room drivers.
What to check the pressure ... I'm a complete layman - where can I check it? on these two tanks red and blue? If so then there is OK.
None of the radiators are even summer, so I don't suppose venting will usually help.

Usually the furnace has a pressure gauge installed where you can see the water pressure in the co. Provide the furnace model I will see

It is not on the stove, but it should be on the installation close to the stove. It says so in the instructions. Do you have one with you?

rodick · Answer

The pressure is 1.8 bar - so it's probably ok.

Pressure ok and DHW works?

rodick · Answer

Yes, it works, there is hot water on the stove and on the tray.

You write that radiators are cold and pipes going to the risers are also cold?

rodick · Answer

Yes, it's cold too.

Maybe you just have the CO valve closed

rodick · Answer

The valve is open, the pump can be heard that it is working, but behind the pump the tube is already cold.

Or maybe the pump has failed. I read somewhere about the case that the pump was supposedly working, but the pump rotor got off and the engine was running loose because the pump rotor did not spin and did not push water

The CO filter may be clogged. There may also be a problem with the three-way valve link here was the topic of this valve Added after 3 [minutes]: Or maybe a simple boiler reset will help.

rodick · Answer

Boiler reset? Any tips on how to do this? I understand that all damn settings will go?

I have not found it, unfortunately, but it can turn off the power for 3 minutes and restart. Yes, it's a divination with coffee grounds.

And wherever any tube is at least a little warm? Before the pump, around the valves? If there is no circulation, the stove will go out after a while but at least some gravitational warm water should go.

you got in the 10th wine pump.
