Vaillant Error Code F.32 – this fault code indicates a problem with fan, fan wiring, electronics or hall sensor. If you need your boiler repaired please get in touch through contact section on this web site.
This time I got called to a Vaillant system boiler Eco Tec 630 Plus showing error code F.32. Boiler would not ignite and go to lock out. Error code F.32 is the same for all Vaillant Eco Tec boilers including conventional and combination boilers. The only difference between Pro and Plus models is that on the Plus models display will show either F.32 or crossed icon of a fan and flue. It can also show both F.32 and crossed out icons as on the picture below. Vaillant Ecp Tec Pro will only show fault code F.32 without icons.
I did all required checks to electronics and wiring and found out that it was the fan that was at fault. New fan got installed the same day, boiler got checked up for combustion and safe operation. Replacement fan pictured below.
