Common Biasi Boiler Error Codes & Faults

Some boiler problems are more common than others. With this in mind, we’ve provided detailed information on the Biasi boiler faults, which are most the most frequent issues that people experience. Then further down, you’ll find a list of all the Biasi boiler codes.

How to fix Biasi 04 error code

The Biasi boiler error code 04 means that there is an error within the primary circuit. This is usually due to there being no water or a very weak water flow within the system.

So, the very first thing to take a look at is the pressure within the boiler. If it’s below 1.5, then it will need topping up with water. Conversely, if you see the Biasi boiler ‘fl’ code, then that’s telling you that the pressure is too high.

The way in which water is added to a boiler can vary between models, so we recommend checking your manual first. If you need to download a new manual, you can do that here. We also have an article on boiler pressure issues which will also be a helpful read for you.

If the pressure is okay, then this Biasi error 04 is likely to be with the pump, which will need an engineer’s attention.

How to fix Biasi 01 fault code

The Biasi error code 01 generally means there is a problem with the burner. This could be blocked jets that an engineer can clean or issues with the wiring or the printed circuit board. Replacement PCBs can be expensive, and if you have an older system, then a new boiler might work out cheaper in the long term.

How to fix Biasi 02 fault code

When the Biasi boiler error code 02 appears, this tells you that the safety thermostat has been activated. This happens when there is a risk of your boiler overheating. Because the casing will need to be taken off, a gas certified engineer will need to carry out some investigative work to understand what’s causing the problem.

How to fix a Biasi 14 fault code

The Biasi boiler error code 14 is displayed when there’s a problem with the pump. Because there may be a risk of further damage being done, then your boiler will probably lockout after showing this code. Unfortunately, this is also one where an engineer needs to be called out as this code is specific to a pump issue that may need replacing.
