Ravenheat Boiler Error Codes, Meaning, Causes & How To Fix
Ravenheat boilers error codes and faults – what they mean and how to fix
No matter which boiler you have, there will be times when a fault develops. Whether that’s no heat from your Ravenheat boiler, no hot water, or even loud banging noises when operating.

Thankfully, the manufacturers provide a set of error codes for each system, enabling us to know what the issue is. That then means that Ravenheat boiler troubleshooting could result in being able to get your system up and running again without needing to call in an engineer or buy a new boiler!
Ravenheat Manufacturing Ltd has variations in the codes displayed depending on the boiler model that you have installed. So, whether you have a WH80 or a Ravenheat csi85, fault finding becomes much easier. First off, we’ll look at the error codes that are most common with Ravenheat boilers.
Then, if you can’t see your error code there, you’ll find a complete list further down. If your problem is not fixable, then we can also tell you how much a new boiler costs.

Common Ravenheat Boiler Error Codes & Faults
So, we’ll start off by delving deeper into the most common error codes and seeing if they might be ones that you can fix yourself. It’s also worth checking your Ravenheat manual for further information.
How to fix error code 01
The Ravenheat boiler error code 01 means that there is a problem with the ignition. The challenge here is that many different issues could cause this particular fault:
- A faulty burner unit
- A damaged electrode
- Damaged ignition lead
- Problems with the spark generator
- Issues with the printed circuit board
Because this results in your Ravenheat boiler not firing up, it means that there is no hot water from your boiler or heating until it’s been fixed. This will mean getting in touch with Ravenheat technical support, who are likely to suggest an engineer’s visit.
Old boiler? is it time to consider a boiler replacement rather than keep repairing?
How to fix error code 09e
The error code 09e means that there is overheating of the overheat sensor. When your boiler overheats, it’s often because one of the safety features has failed. This then means that the boiler goes into lockdown mode to prevent what could be unsafe use. Again, this will mean an engineer coming out to establish what’s caused the problem before you’ll then be able to get hot water and heating.
How to fix error code 28
This error code means that there are low water levels within the boiler. Now, this could lead to a potentially dangerous situation because the heating surfaces become overheated.
Then, when cold water is added. It rapidly becomes steam which can expand to over 1,500 times its volume. If there’s not enough room for the steam, then the pipe could rupture in your Ravenheat boiler
So, with all that in mind, you’re probably not too surprised when we say that this is on for a qualified Gas Safe engineer to come out and fix for you. Even the best combi boilers and system boilers have to give up one day, lets hope it’s not today.

Summary
When you’re experiencing Ravenheat boiler problems, it becomes an absolute priority to get everything working quickly and efficiently. When there’s no hot water or heating it’s no fun for anyone.
The manufacturer’s error codes provide a bit of information, and at times, they’ll tell you about problems that you can fix yourself. Check out similar manufacturers’ boiler problems in the form of Ariston Error codes & Firebird error codes. Both these lesser know manufacturers have their issues too.
If your boiler keeps on breaking down or if the issue is one of the main components, then the time may have come to look for a replacement. Boiler Central have removed all the stress for this process by allowing you to get a fixed price and providing suggestions for a boiler that meets your needs. Then you can even select the day of boiler installation, which could be just a few days later!
