Bolier problems

[callay1920]

I am having problems with my vaillant ecotec combi boiler. It is currently flashing f.22 at me. Afetr reading the manual, i have discovered that means there is no water in the boiler. I was wondering if anyone knew how to fill it up as the maunal does not indicate this?

There must be a filler loop underneath the boiler, it's a small flexible pipe that's a silver colour. Turn on the valve and wait til the pressure gauge says 1bar, this should do it....

I agree with the above but,why has it lost water eg leak or pressure relief valve not working right ?keep an eye on the pressure relief vavle
