i have asked before nobodys replyed yet!
my vaillant boiler keeps showing faultsf.22 and f.29 when we try heating .whats wrong ,someone must know!!!!!!!!!!!!!!!!!!!!!
you really need the manual to see what these faults mean, it could be that ur water pressure has dropped, check on the guage it should read between 1 and 1.5 bar, if its lower than 0.5bar u need to top it up, if u get no joy get in contact wiv vaillant and email them at their website.
