Got exactly the same problem with mine. Manual says f28 = fault in gas supply, gas pressure too low. Boiler will ignite but goes out within minutes? HELP!
After trying many combinations of various button pressing on the front of the boiler a friend of mine suggested checking that the gas meter was ok and after realising the boiler went off around the same time I'd put the hoover back under the stairs (where the gas meter lives) I noticed that I'd simply knocked the lever into the off position.......Der !

I had the same problem and instead of the hoover it was a shoe in the shoe cubbord. The gas leaver was turned off by accident and Vailant shut itself down for safety. Turned the gas leaver on again and all is back to normal. I was definately worth the try. Thanks.I had the same problem and instead of the hoover it was a shoe in the shoe cubbord.

Thank you Regmeister for your advice about checking the Gas lever,, mine is not clear when it is on or off, I was getting the F 28 and F29 on my new Combination Valiant Ecotec Boiler, But after reading your post, I went back and started the boiler without changing the lever and it worked...Thank you again, you saved me stress and money, I hope there is no other faults and that it will work fine, I will make a note of the on and off positions of the Gas lever, not to make the same mistake again...
