Whilst there are many different types of Worcester Bosch boilers on the market, there are a few common threads that bring the majority of them together, such as the lights and what they mean. 

Boiler lights serve the purpose of showing you that everything is working properly as well as alerting you to any errors that may have occurred. As a result, it’s important to know what each one could mean, in the event of a malfunction. 

What does the red light on my Worcester Bosch boiler mean?

Some boilers have flashing lights when in error state – with a modern Worcester boiler, this flashing light is usually blue and means that there is a significant error, meaning your boiler is in need of a check from a gas safety engineer.

What does the green light on my Worcester Bosch boiler mean?

The green light on a Worcester Bosch boiler typically indicates that the burner is operating properly, which is a good sign. However, sometimes the green light can go off, with the boiler still working fine.

 There are a couple of reasons for this, such as LED Failure or PCB Failure, essentially, the things which power the light on the boiler panel. 

If the failure is with the LED this is not a huge problem, but if it is with the PCB (Printed Circuit Board), this can be a more expensive fix. If you have an older boiler, this can often be the first thing to go and it can be tricky to run diagnostics once this has happened, so we would recommend considering a replacement boiler installation.

What does the blue light on my Worcester Bosch boiler mean?

The blue light on a Worcester Bosch boiler is typically there to highlight that the boiler has power going to it. If there is no blue light showing, there are again a couple of possible explanations, including LED & PCB failure, as above. 

In addition, it may point to a socket failure – it is worth checking a few other appliances in the house to check that they work OK, using the same socket that the boiler is usually plugged into. This could highlight an issue with your electrics, instead of your boiler itself.
