Ferroli Boiler Guide: FAQs & Troubleshooting 2021

Being one of the most common manufacturers of UK boilers, we come across our fair share of faults with Ferroli boilers during our day to day operations.


Boiler faults are something that all homeowners will need to deal with from time to time, and those whose homes operate on Ferroli boilers are no different. However, these problems aren’t always as complicated as they look and many can be solved without the need to call a boiler specialist.


To give you a little more insight into the inner workings of your boiler and to help you understand some of the main problems you might come across from time to time, here’s our guide to troubleshooting your boiler and the answers to a few frequently asked questions regarding Ferroli boilers.


Common Ferroli Boiler Problems


Here are some of the more common faults that Ferroli boiler owners may encounter in some circumstances.


Low Boiler Pressure
This, like many of the problems on this list, is certainly not specific to only Ferroli boilers – low pressure is one of the more common faults that might occur within boilers of all makes and models. On your Ferroli boiler, this will be indicated by a flashing green light or by the F37 code.


Signs of low boiler pressure occur when the volume of water circulating within the boiler system has decreased. The boiler gauge on a Ferroli boiler in good working order should display that the pressure is between 1.0 and 2.0 – if the number on the display drops below 1.0, you’ll need to repressurise the boiler.


You should be able to do this by following these steps:

  1. Switch off the boiler and give it some time to cool down
  2. Locate the filling loop (a metal hose with a valve at either end) and, if not already attached, secure this to the system.
  3. Open the valves and allow water from the mains into the heating system – be careful not to over-pressurise, only allowing this to fill until the gauge reaches 1.0.
  4. Close the valves to stop the water flowing and release the filling loop.


A Leaking Boiler

If your boiler is leaking from the bottom, there could be a number of different issues at play – the best way to determine what the cause is and to get this fixed is to consult a Gas Safe registered boiler specialist.


This is a slightly less common problem and is usually related to a broken internal component. Fortunately, there are many cases in which a boiler specialist will be able to repair the issue.


Radiators Aren’t Heating

More often than not, this isn’t a fault with the boiler itself – it’s more likely that your radiators just need bleeding. This is fairly easy to do for yourself once you know how, though many households do call on the help of a professional to make sure that the process of bleeding the radiators is carried out properly and thoroughly.


If you do attempt to bleed the radiators for yourself and this makes no difference to the working order of the radiator, we’d recommend bringing in a specialist to identify where the issue lies.


Boiler Is ‘Kettling’

For your boiler to be ‘kettling’ means that your boiler is making noises of a bubbling, whistling and popping nature whilst it’s in use. This may happen constantly or at intermittent periods – either way, it’s a sign that there’s a build-up of limescale, ‘sludge’ or other materials within the heat exchanger.


We’d recommend that you call on a specialist for this issue, especially if your boiler is less than ten years old when these problems begin to occur. However, if your boiler is approaching around or over a decade of use, chances are that you’ll need your boiler replacing.
