What are the Biasi boiler error codes? We have a complete list of Biasi boiler error codes for every boiler.
Biasi has over 74 years of manufacturing experience. But does that mean they make great boilers? If you’re viewing this page you are probably cursing your Biasi boiler for breaking down and flashing a fault code at you that makes no sense.
That’s what this Biasi fault code article is for. We will list every error code for every Biasi boiler so that you can identify what the problem is with your Biasi boiler to allow you to get an idea of how much it’s going to cost to fix (if it’s out of warranty).
If your boiler is getting on in years or it’s not the first time it’s broken down and you think that any more money put into fixing your boiler would be wasted money; then get a new boiler quote from WarmZilla. It only takes a few minutes of answering some simple questions online about your home and we’ll show you a list of boilers suitable for your heating needs.
With WarmZilla you can pay for your boiler using our boiler finance options. 0% APR finance is available over 2 years on selected boiler models. We guarantee to offer the cheapest combi boilers on the market.
In 1938 Leopoldo Biasi opened a small thermomechanical business in Italy. In the 1940s he opened a facility to manufacture residential boilers. Biasi UK was formed in 1990 to promote boilers, towel rails, and radiators throughout the UK.
Biasi boilers don’t have a great reputation amongst heating engineers as being particularly reliable, but heating engineers all have different opinions on what boilers are good or bad. So what do customers think about Biasi boilers?
If we take a look at Biasi UK reviews over on Trustpilot, it doesn’t look too bad at first glance. 4.1 out of 5 is a pretty solid score. However, 21% of Biasi reviews on Trustpilot are bad, which is a bit concerning. It seems that amongst customers, Biasi boilers divide opinion, many are happy with their boiler and the customer service and some curse them just as loudly.
Biasi offers a range of combi and system boilers with different kW options to suit different sized homes. Biasi is a budget boiler brand, so they are quite cheap but they aren’t as reliable as more premier boiler brands such as Worcester Bosch.
Now that you have a bit of background on Biasi boilers, let’s get into the Biasi boiler error codes. We provide these error codes to help you identify the issue with your boiler and hopefully fix it yourself. If you identify an internal issue with your Biasi boiler then you will need to contact a Gas Safe Engineer to come and take a look.
Biasi boilers come with a warranty length of between 5 and 7 years depending on which model you choose. If you’re in warranty, get in touch with Biasi and see if you can get them out to take a look (and hopefully fix) your boiler.
Check out the table below to find your Biasi error code and see what the fault code on your Biasi boiler relates to. Biasi fault codes are generally the same across all their boilers, which makes it easier to identify the issue with your boiler. If you can’t find your fault code in the list below then we have listed every single Biasi boiler manual below that, the answers you seek shall be there!
