As I have good water pressure but the flame don't come .
No it is not
Testimonial: "so how I can make flame comes as i clean copper tube with acid and its clean now !"
Acid is way too strong for cleaning on that the valve comes up on water pressure pushing up on the diaphram .which pushes up on he gas valve. You may have done to damage the water section using Acid.
Thank u Paul , I used to clean tubes with acid and water for 10 years and its going alright ,,, but this time the flame become weaker not too strong as before , any suggestion where is the problem ?? Many thanks to you !!
In the water section

SOURCE: Vaillant turbomax 28 constant hot water problem.
got your fix, its a calcium buildup in the heat exchanger, and more than likely the rest of the unit, you will need to flush the unit with about 4 gallons of vinegar, you will need to recirculate it for about 20 mins through the unit, then flush with clean water, hook it back up, it might take a couple of mins for it to run properly, but it will, I have had the same problem with Rinnai on demand hot water systems, and it worked like a charm, check the filter thats inline as well, make sure it isnt plugged, clean if needed, also if you dont have a soft water system inplace, you might want to think about buying one and having it installed, that will reduce this from happening again for alot longer period of time, hope that helps
SOURCE: I can't turn the bar pressure up on my Vaillant VCW 221 Boiler
on the pipework below there may be a silver braided hose with one or two valves on the end. turn the valve(s) so the handle is inline with the pipe this will allow water from the mains supply into the heating circuit , remember to keep an eye on the pressure gauge. fill the system to 1bar cold then shut down the valve(s). turn on the boiler and it should be ok, if you lose pressure again then you may have a leak somewhere which needs to be found.
SOURCE: Vaillant Mag 325 warm water only full pres. cold low pressure
you need a certain amount of water pressure for the water heater to turn on this is actaully one of the biggest problems that all manifactures forgot to tell anyone it is normal for the computer to shut down beings it is designed to heat water at a fast rate when you turn the water down, it's not enough pressure for for sensors to turn on to heat the water so turn on the spigot a little more and enjoy

More information is needed.
Is this new installation? Or old installation that has stopped working?
What is the product-type and model number?
Add a comment, and I can look up possible manual.
