RiffRaff   10 #1537 Posted September 28, 2020 Does the 'circa 7 year' white goods life span also apply to boilers? Our Vaillant has been showing an F22 error every morning for a few weeks, and needs filling to get rid of the 0.3 (bar?) warning. It's just over 5 years old, and has only been controlled by a thermostat, rather than the rather erratic timer. Share this post Link to post Share on other sites Share this content via...
Cyclecar   24 #1538 Posted September 28, 2020 Check you have no leaks. Even a drip drip can affect the pressure retention. Hope its not under the floorboards.... Share this post Link to post Share on other sites Share this content via...
zach   235 #1539 Posted September 28, 2020 (edited) Fairly sure I get that on mine. In the Winter it's nigh on every day the fault shows and I have to fill the system. During the warmer months, it never happens, even if the heating comes on every now and again.  I just turn the 2 valves and top it up. I've had engineers out 3 times now and they can't find the fault. No leaks on the system but I do hear a low banging noise from the boiler at times. A couple of things mentioned that could be fault was the vessel (whatever that is) and the pressure relief valve.  Mine is also just over 5 years old, last engineer came and did the service and gas test a month ago. As it gets colder, I'll soon find out if it's fixed!  Edited September 28, 2020 by zach Share this post Link to post Share on other sites Share this content via...
TonyB14 Â Â 10 #1540 Posted September 28, 2020 could be the pump or the pump lead may be defective, we usually google possible faults prior to calling engineer out Share this post Link to post Share on other sites Share this content via...
*Wallace*   333 #1541 Posted September 28, 2020 There’s a plastic filter cup under the boiler see if it’s got sediment in. Share this post Link to post Share on other sites Share this content via...

In fact, the F22 problem started appearing sporadically a few days afterwards, but has gathered momentum since having the heating on. I gather that Vaillant aren't a particularly 'respected name' to those in the trade, so perhaps 5 years is about their limit.  5 minutes ago, *Wallace* said: There’s a plastic filter cup under the boiler see if it’s got sediment in. The thing with the bar magnet in? All cleaned and flushed out during the service, and we do it every 3 months-or-so as well.  Share this post Link to post Share on other sites Share this content via...
*Wallace*   333 #1543 Posted September 28, 2020 (edited) No it’s to the right of that as you look at it sort of clear plastic container full of water usually sediment in the bottom of it. Needs a half turn to drop it out and clean up then fill it with water and replace. I think it’s called a condensation trap.
