Are you looking for a Bristol heating engineer for a Ferroli Boiler repair? We can help! Call 03333 441 399
Ferroli has been producing heating appliance design and development for more than 50 years and now operates in over 100 countries worldwide. The full range of their boilers are manufactured in Verona, Italy.
With every boiler, Ferroli manufactured boilers experience problems with constant use and when the winter season kicks in. Here at Plumbing Care Services we serve Bristol, Somerset & Gloucestershire for all Ferroli Boiler customers. Here is a list of fault codes and possible issues that may arise with these boilers.
Please note that we do not suggest that you try to rectify any faults listed as this may put your safety at risk, and also cause any warranties the boiler may have. The best thing to do is call us at Boiler Care Services for 24/7 emergency repairs.
Check for any leaks from the boilers pressure relief valve, or any of your homes radiators. If you can’t locate this, the problem is that it’s usually an issue with the expansion vessel which will need to be repressurised. This can only be repaired or re-set from a qualified engineer which is a quick fix. If this is not the fix required the boiler may need a replacement vessel.
This is a particular fault with this brand of boilers, as the shut valves tend to wear out. The only option is to have these replaced by a qualified engineer.
The boiler isn’t coming on at the correct time. This is highly likely to be a fault with the boilers timer. Thi is a simple and relatively cheap fix for any qualified engineer to complete.
If the boiler is producing a puffy sound of air then the problem is likely to be with the boilers flue. This can be from a number of reasons as the boiler gets more use down the years from flue duct corrosion of loose joints within the flue. If this is the case then an engineer is required to replace all the parts.
The printed circuit board is likely to be malfunctioned. This needs to be properly checked by an engineer to ensure that there is a supply of electricity reaching it. If this is the case, then a new PCB will need to be installed.

If your Ferroli boiler is showing an error code, here are some pointers for you. If the code on your Ferroli boiler is not listed, let us know when you call for your repair. Please note it’s always best to look at the owner’s manual for the full list for your specific model.
