Cannot refill boiler

[trixta99]

Hi All

Hopefully somebody here can help me as my regular plumber keeps letting me down

I have a Vaillant ecotec plus 837 boiler and I caanot get it to refill. I emptyed the system to install a new radiator valve but when I tried to refill the system its not doing anything.

I have turned both of the grey switches under the boiler but I cannot get it to refill. I could not hear the water going into the boiler so I disconnected the silver flexi pipe on the filling loop and turned the right grey switch and water came through. When reconnecting the silver flexi pipe, the water does not seem to be going into the boiler.

I have not had hot water for 4 days now as my plumber keeps saying he will try and make time (he is the one who installed this boiler which is now about about 4 yrs old)

Also not sure if this is connected to this issue but on my control unit (in living room) it also has a message saying "service heat genrator" - this message was not showing before.

Is there any thing I can try to do myself to fill system or am I at the mercy of my plumber and when he has time for me

Any help would be greatly appreciated.

Hi trixta,

Perhaps you are just turning the knobs instead the valve.
You could take both handles off via a chrome cross headed screw and try then with a spanner to turn you should then here water filling.

Maybe you could also upload a picture of the filling loop

Firstly as Matchless.plumb says you could be just turning the plastic and not the valve. Try turning a quarter turn with a spanner. Unfortunately sometimes the valve its self can become blocked. If that happens you will have to get a Gas Safe Engineer to look at it. The message saying " service heat generator" is your boiler. Have you had it serviced recently? if you have get them to pop back and reset the service schedule. If not your boiler needs servicing.

Thanks Moonlight & Matchless for your quick replies

It is due a service in July but will get it done asap

I took off both handles and tried with a spanner but unfortunatley no joy!

I have uploaded pics of my filling loop.

which end of the flexi did you disconnect? Left hand as we look at the picture or the right? Just re-read your post. Ignore this

Have you turned off any other valves?
do you get water from your hot and cold taps?
Any pressure showing on the boiler gauge?

Moonlight - left hand and water came out wen i turned the handle on the right.

Scott- it saying 0.4 bar on the digital display and I get water from hot and cold taps (although hot tap water is not 'hot')
I havnt touched any othet valves.

Have you ever topped it up before?
Could it be you just have poor water pressure and its very slow to fill or 0.4 is the max you can get?
