When your boiler just isn’t doing its job, trying to find out what’s wrong can be frustrating, especially if it appears to be functioning while a component inside has failed. If you’re lucky enough to still have your user manual, you can often look up some common faults, and depending on your model, the boiler itself may display an error code that you can then match up. If that manual is long gone, we’ve compiled a list of the most common boiler faults we get called out for, what signs to be aware of and how to deal with them the right way.


  1. Low Water Pressure

Low water pressure can happen for a number of reasons but it’s normally easily fixed by pressurising your system. If this doesn’t make a difference, give us a call straight away to check it isn’t something more dangerous like a leak or a blockage.


  1. Flame Failure

Flame failure or no gas is another fault that’s easily checked. If you have a gas hob or an open fire, test to see if gas is present there. If it is, simply reset your boiler, as the error code could’ve been caused by a minor electrical fault. You should always give us a call if this doesn’t clear the code away, as it could be something more serious like a component failure, and we’re always happy to talk things through with you on the phone.


  1. Blocked/Frozen Condensate

A blocked or frozen condensate is one of the most prevalent problems, especially now we’re well into winter. If you can locate and access your condensate pipe, you can attempt to clear or defrost it yourself using warm – but not boiling!- water or a hot water bottle, but its always safer to get an engineer out to ensure the pipe stays undamaged while being thawed out.

If your boiler fault doesn’t fit any of these descriptions or you have determined one of these is the problem, give us a call today to start figuring out the next steps to get your boiler back to its best.
