If you’re experiencing an issue with your boiler, you should always make your first port of call to check whether or not there is a visible error code. Often, if your boiler isn’t working properly or isn’t functioning at all, there will be a fault code that you can then report to your Gas Safe engineer. One error code which is commonly seen on Vaillant boilers is the F28 fault code.
This code may be seen on several different Vaillant boilers including the Vaillant ecoTEC Pro, the ecoTEC Pro Plus and the Turbomax Plus 824/828E boilers. Essentially, this code means the unit cannot ignite, and therefore, your home will be left with no hot water or central heating.
In simple terms, this means that the flame the water has to pass over to heat up before it reaches your hot taps or circulates around your central heating system isn’t able to light up. There can be a few different causes of this error code, and therefore, you’ll need a registered Gas Safe engineer to visit your home to diagnose and resolve the problem.
What Are The Causes Of A Vaillant F28 Fault Code?
There are several reasons why your Vaillant boiler may not be igniting and may, therefore, be displaying an F28 fault code. These reasons include:
- No supply of gas. A very common reason for the Vaillant F28 fault displaying is that no gas is being supplied to the property. Perhaps this is because you have run out of credit, or maybe the gas meter has been turned off, or there may be an issue with the company that supplies your gas. Before you call one of our engineers, test some other gas applies in the home, for example a gas fire or your gas hob. If these are lighting and working normally, you can be confident that the fault lies specifically with the boiler.
- Defects in the spark electrodes. Gas may be being supplied to your boiler, but there could be a fault when it comes to create a spark to ignite the flame. Over time, the spark electrodes can wear out and require replacing. If you think this is the cause of the problem, you need to contact your Gas Safe engineer since you can’t fix this issue yourself.
- The condensate pipe is frozen. All condensing boilers have a condensate pipe. This sends the waste gas outdoors for safety. Since these pipes are located outdoors, though, they may freeze in the winter months if the temperature drops below 0 degrees. As a result, the boiler may stop working. If you believe that this is the cause of your error code, you may be able to resolve the issue yourself. You can thaw the condensate pipe if you take the right measures to ensure that you cause no damage. However, if you aren’t confident about tackling this yourself, an experienced boiler engineer can professionally and safely deal with the problem to get the boiler functioning once more.
