3 Baxi Boiler Problems & How To Fix Them | Error Codes, Faults & Lights
Wouldn’t it be great if there were a few easy ways to fix those problems with your Baxi boiler? Well, we aren’t ones to blow our own trumpet, but we think we’ve found some helpful hints do exactly that.
In this dedicated guide, we aim to cover a whole host of common issues and faults, such as your Baxi boiler not firing up or even your Baxi boiler not working at all. The best bit is that many of our fixes are able to be done yourself, so you might not even need a professional to do it for you.
However, if you don’t have experience in fixing boilers or think that the issue is much more serious, then please don’t try to fix it yourself. Your best bet is to get in touch with a qualified Gas Safe registered heating tradesperson who’ll be able to sort those Baxi boiler faults for you.

1. Boiler Lockout
If you think that your Baxi boiler may have gone into a locked out state, then the usual cause of this is overheating. This is a fix that you should be able to do on your own and is actually quite easy to solve.
How to Fix: The first thing to do is check for any pressure problems with your Baxi combi boiler and top it up if the pressure is lower than normal. If you are asking yourself ‘how do I fix the pressure on my Baxi boiler?’, it’s as simple as turning the pressure valve on the pipework under your boiler. To find the exact spot, please refer to your manual.
Once you’ve done that, if you have the 1PF version, you will need to look for the orange gauge on the left of the boiler, where you should also see a red thermostat that signals any overheating. If you press this, that should do an official Baxi boiler reset.
If you have the 2PF version, then just turn the same stat to off or rest, before switching the whole thing back again.
Generally, that should fix your issue, but if it does continue to persist then you may have a problem with your pump or there could be some blocked pipework that needs clearing. If you think that might be the case, then you’ll need a heating professional to give you a helping hand.
2. Leaky Boiler
It’s everybody’s worst nightmare to come home from work to find a boiler leaking water and not doing its job properly. Unfortunately, it happens more than you would expect and tends to be fairly common in the Baxi 133HE Plus range.
There’s an easy way to spot if you are experiencing this kind of fault, as you will tend to find water dripping out from the bottom of your boiler until. This range of boilers was built with plastic housing around the valves and pumps, so because of this, they tend to start cracking or wearing away after more than five years of use.
How to Fix: The best place to start is by replacing any plastic housing that sits around the valves and pumps, and although that might sound like an easy job, they are often a bit tricky to replace and it is actually a time consuming job. Because of this, it’s sometimes tempting to just change the washers, but this is only a temporary fix and you’ll like the experience leaking again pretty quickly.
For that reason, we wouldn’t advise just changing the washers yourself, as not only will you be wasting your own money, but you’ll be wasting your time as well. Instead, we’d suggest just changing the whole of the housing, which may seem expensive, but will certainly work out better for you in the long run. Saving you all important time and money.
3. Ignition Problems
If your Baxi boiler is not firing up at all, then you might be wondering “what is wrong with my Baxi boiler?” or “why does my Baxi Boiler keep cutting out?”.
Often, there is no need to be too alarmed, as Baxi’s boilers are known to be prone to cutting out. It’s likely that the issue is down the combustion chamber seals, which regularly become loose over time and need replacing.
How to Fix: If you notice that your chambers seals are looking a bit worse for wear or even have splits in them, then they are definitely in need of being replaced. Once you do this, the problem should go away, but if it doesn’t, then you are better to get in touch with a registered heating engineer.
About Baxi Boiler and their Problems
The Baxi brand has long been a staple brand in Britain and from the 1960’s where practically the only choice on the market, with their ‘back boilers’ a really popular choice in houses around the UK.
However, they no longer rule the market and with some many competitors challenging for the top spot in the industry, they’ve had to step up to the plate and compete with the more modern type of boilers.
Their combi-boilers are certainly up there with the best these days, and are actually one of the most reliable that are available, with any new parts available in most trade or DIY stores across the nation.
That means that Baxi is still a leading player and is a hugely respected brand to UK consumers, especially with a 10 year guarantee to boot.
