The E110 fault code on your Baxi boiler signals a vital overheating issue that triggers an automatic shutdown for safety. You'll typically encounter this error when your system's water pressure drops below 1.0 bar or when there's trapped air in your radiators. While you can try a quick reset or pressurise the system yourself using the filling loop, persistent E110 codes often need professional attention. It's essential to maintain proper pressure levels between 1.0-2.0 bar and schedule regular maintenance to prevent these issues. Let's explore exactly what steps you can take to resolve this common boiler hiccup.
Key Takeaways
- The E110 fault code indicates critical overheating in Baxi boilers, triggering an automatic shutdown to protect system components.
- Low water pressure, typically below 1.0 bar, is the most common cause of the E110 error code.
- Resetting the boiler and checking water pressure between 1-1.5 bar can often resolve the fault immediately.
- Trapped air in radiators must be bled out to prevent circulation issues that trigger the E110 code.
- Professional help is needed if the fault persists after basic troubleshooting or if pump issues are suspected.
What Does The E110 Fault Code On A Baxi Boiler Mean?
When your Baxi boiler displays the E110 fault code, it's signalling a critical overheating problem that requires immediate attention.
Think of it as your boiler's way of waving a red flag to protect itself and your home's safety.
You'll notice your boiler has completely shut down, and you're probably wondering why there's no hot water or heating.
Don't worry – this is actually your system's built-in safety feature doing its job!
Regular boiler maintenance can help prevent these overheating issues from occurring in the first place.
If you're hearing unusual banging or gurgling sounds along with the E110 code, it could mean there's a problem with your heat exchanger or water circulation.
Understanding these warning signs is your first step toward getting your heating system back on track.
What Causes The E110 Fault Code?
Several key issues can trigger the E110 fault code on your Baxi boiler, with low water pressure being the most common culprit.
When you're troubleshooting these common boiler issues, you'll want to check if your pressure gauge reads between 1.0 and 2.0 bar – anything below 0.5 bar means it's time to repressurise your system.
Other causes include faulty temperature sensors that might be giving incorrect readings, or circulation problems that could be making your boiler overheat.
You might also have trapped air in your radiators, which is an easy fix – just give them a quick bleed.
If you're experiencing gas supply issues or problems with your pump or diverter valve, don't try to tackle these yourself – it's best to let's handle these more complex issues safely.
How Do You Fix The E110 Error Code On A Baxi Boiler?
Now that you understand what triggers the E110 fault code, you can take specific steps to resolve it.
When you're tackling error troubleshooting, follow these proven solutions that we've used countless times during boiler maintenance visits:
- Reset your boiler first – it's like giving your system a fresh start
- Check your water pressure's between 1-1.5 bar when cold
- Top up the pressure using your filling loop if it's below 0.5 bar
- Bleed your radiators to release trapped air
- Inspect temperature sensors for secure connections
If you've tried these steps and you're still seeing the E110 code, don't worry – you're not alone.
While these fixes often do the trick, sometimes you'll need a Gas Safe registered engineer to tackle more complex issues like pump or valve problems.
