Hi, can anyone tell me the location of the filling loop on a Vaillant EcomMax 835? I have just removed a radiator and need to top the system up, but I am unsure where the loop is. Thanks for any help you can provide.
Standing in front of the boiler, right hand side, underneath at the front. 2 very small black isolating taps either end of approx 6mm pipe. You will have to look up to see them.
You will have to remove plastic decorative cover under boiler first if fitted.
You are an absolute star!! Everything now back to normal - I had tried each of those taps, but, didn't realise you needed to do them both together. Thanks for your help.
