Common problems with Ferroli boilers

Ferroli Boiler Pressure loss

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.

Ferroli Boiler leaking from the base of the boiler

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.

Ferroli Boiler not functioning as it should

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.

Ferroli Boiler is only igniting for a short period of time

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.

Ferroli Boiler in ‘lock down’ mode or not firing up as it should

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.
