VAILLANT ECOTEC PLUS F22

[georgeegee]

Lost about a pint of water through loose radiator connection. Now error F22 but have no tap heads underneath to refill (there are valves on flow/return which can be turned with pliers but am unsure whether to turn these). I read the following on forum:

'Ecotec plus range needs the boiler/pcb to purge the system/heat exchanger of air by setting 'P 0' on turn on. Failure to do this could end up with an F76 fault and the only way out of this is a new primary heat exchanger'

and would like to know how i then set P 0 on turn on.

Hope someone can help...

you need to repressurise your boiler before you do anything else, there are two grey knobs underneath your boiler, open them and you will see/hear your boiler fill by the pressure guage, when you get to 1 bar ,(the needle should be about the 9 o,clock position) turn the knobs back where they were, you shouldent need to do anything else.

there are valves on flow/return which can be turned with pliers but nothing that i can turn on by hand. is it these valves that i should turn??

you have to stick your head right under the boiler, you will see the grey handles(they look like a small T ) I will see if I can find a picture of them.

I am assuming this is a combi is this right ?

all i know is that it is a valiant ecotec plus 637 R1 condensing system boiler. the diagram shown doesn't match my boiler (i have fewer pipes.) and there are certainly no grey valves for manual turning

sorry I was assuming it was a combi there should in that case be one of these somewhere in you house.

Try looking in the airing cupboard next to the hot water cylinder.

There may even be another pressure gauge with it as well.

Christmas Eve 5am...Woken by my better half to be told "boiler not working"..."panic".... realised there was no pressure.....I searched through my instructions but was unable to find out how to manually increase the pressure, so I "googled it"....and got your answer....

Thanks very much.....I will keep an eye on it, to see if it drops......I became a member after reading your post......so if you have a "referal system"....its one for you.....

What if you can't find the filler pipe?
