What is used to detect faults in a boiler?
Establish cause of the boiler fault: Some combi boilers have a built-in diagnostic system that illuminates LEDs or neon’s, either on the control board or the user panel. The fault code displayed will indicate the specific type of fault as listed in the manufacturer’s instructions.
How do you fix a combi boiler problem?
The Fix: First, go outside locate the condensate. If possible, try using a kettle of hot water to thaw it out. Next, remove the condensate pipe below the boiler and drain to a bucket. That should fix the problem, but you should consider asking an engineer if he/she can retro-fit a condensate trace heater for future.
Why is the pressure on my boiler high?
Boiler pressure is controlled by the expansion vessel, the balance of air versus water in your central heating system. Too little air in your expansion vessel and the pressure may become too high. This is why it’s important that the installer work out the cause of your boiler’s high pressure.
Do you need a carbon monoxide detector with a combi boiler?
If you have any gas appliances, including a gas fired boiler, then the short answer is Yes. We strongly recommend that you install a smoke alarm and a Carbon Monoxide (CO) detector in your home, for you and your family’s safety and anyone living in your property (landlords, take note).
How do you check a diverter valve on a combi boiler?
After you remove the lid of the boiler, you have to locate the diverter valve mechanism. Run tap water on hot and observe the diverter valve. If you run hot water, the valve is supposed to close in order to divert it to the tap, meaning it should move. If you see no movement, then it’s stuck.
When does a combi boiler need to be used?
During the heating season the combi boiler runs as needed to heat a structure and provide hot water for showers, sinks, and other hot water appliances. During the summer months the combi boiler only fires when there is a call for domestic hot water.
Can a combi boiler be used for hydronic space?
Providing hydronic space heating and domestic hot water production in one compact combi boiler is a big advantage, especially considering the low installation and operating costs. However, combi boilers are not ideal for every home and heating application.
What does a diverter valve on a combi boiler look like?
Here is what a diverter valve looks like (Worcester Bosch). The diverter valve on a combi boiler works much like a lock on a canal would. It opens and closes to allow heat up both hot water and the water in the heating system which provides heat to radiators and towel rails.
How can I find out what is wrong with my boiler?
Take a look at the front of your boiler; you should see a data badge telling you the make the model. You should be able to type this into Google and find either a digital version of the owner’s manual, or a list of common boiler faults for that particular make and model. This should hopefully help you diagnose what’s wrong with your boiler.

Why are wall hung and combi boilers bad?
Wall Hung and Combi condensing boilers have poorly designed critical water and air passages which easily become fouled over time reducing efficiency, requiring more maintenance, and shortening the boiler’s life.
