the boiler does not start

Ah OK. Sorry buddy

I'm hearing solenoid energise and a brief second of ignition before flame fails. The only time you will experience smoke/gases coming back through air intake is if the pressure inside chamber and flue is greater than atmospheric.
Of course there could be more going on but I'm willing to bet the attending technician will find a blocked chamber or flue.
Please do not keep trying to ignite the boiler, find a decent engineer to thoroughly look over it.
From what I can see in the video the bearings will definitely need replacing soon, the oil flexi looks in a bad way and could perish at any time, plus anything else that I can't see in the video.
Put your immersion heater on for now so you at least have hot water.

Hi, very accurate diagnosis. There was a plumber at my place and he found a blocked chimney. Thanks again

Hello. I will refresh the topic. the boiler after cleaning the chimney worked well for 1 day. After this time, he works as in the attached movie. After opening the lid, it starts working normally, after closing it works, pauses, works and the sound changes. Maybe the flue is not well cleaned? I feel the exhaust fumes more in the room. I am asking for suggestions. Thank you.

I'm concerned by what you've written. I cant make out anything in that video. For demonstration purposes only please upload another video showing the whole boiler and flue please. I only want you to fire it up once, you say you can feel POC's (products of combustion) in the room? This is EXTREMELY dangerous and is an immediate risk if that is the case.

@robert-o1978 can you update me please? I fear you may have been running the boiler

Hi I'm sorry I didn't write back. The problem was poorly cleaned flue. The whole problem is that the chimney flue is clean at the top while it is dirty at the bottom. The boiler is permanently in the wall and cannot be moved. At the top of the boiler is a permanent chimney knee. I had to use an industrial vacuum cleaner that pulled out a lot of ash. The boiler is now working normally. I hope this helped. The plumber had cleaned it before but he didn't do it right.
