I was having a late start yesterday. After breakfast, still in dressing gown and jim jams I finished sewing a scarf I'd made for a friend's birthday, then pottered about doing odd chores. So it was mid morning before I stepped into the shower.
Eeek!!! The water was freezing. Yup, the boiler was showing zero signs of life, except for a mysterious flashing fault code, F22. Digging out the user manual I found the F22 code relates to low water pressure. Now as any Bristolian knows, Bristol Water have spent forever digging up roads and laying new pipes, so I rang 'em. Any problems in my area with low water pressure due to work in progress? Nope. Nuffink.
Oh, poop! I dithered and fretted and Googled, and considered the option of calling out a plumber or heating engineer. Then I considered my bank balance, which is looking feeble. Then I Googled some more. Finally, I found the solution. Simples, as those dratted meerkats say.
If you get F22 as a fault code on your Vaillant boiler, it really can be easy to fix, even for someone who's ridiculously scared of messing with anything gas or electrical like me. (Honestly, I'm such a wuss!)
All you do is turn the left tap clockwise one twist, wait a couple of seconds and turn the right tap one twist. You'll hear water gurgling and in three or four seconds you'll see the arrow on the pressure dial begin to speedily rise. When it's in the green turn off the taps. That's it. Providing the only fault was low water pressure (and nothing to do with leaky central heating pipes) your boiler should spring back into life. Listen, if I can fix this kinda fault, then you can too.
So today I'm going to be showering in blissfully hot water. Lovely, and fixing the boiler didn't cost a penny. How frugal!
