I have listed a few of the most common boiler breakdown problems below to obtain the boiler backup and working You awaken one morning expecting to jump in the shower only to find you have no warm water, you go and check the boiler and notice a fault code is showing on the display, just what exactly do you do You need to discover what the fault code is and why it has made the boiler breakdown All boilers are supplied with a users manual, inside this manual will undoubtedly be listed all the fault codes and the reason for the code to display https//wwwscsplumbingandheatingcouk/ is only a guide on which to check on for, sometimes it can be quite a combination of problems, but it's a starting place to try and trace the problem Sometimes it's a magic pill just by pushing the reset button, other times it can be a bit more involved Most boiler breakdown fault codes could be avoided just by keeping your boiler regularly All boiler manufactures recommend having a boiler service carried out each year to keep the boiler working since it was designed for A boiler can be like a car engine, if left un-serviced it will eventually breakdown and may possibly be costly to correct Just about the most common boiler problems is low water pressure, that is caused by the water within the whole of the system dropping to a point where in fact the boiler sensor senses low water and throws up a fault code and locks the boiler out Low water pressure can mean many things, it may be a leak somewhere on the machine, a radiator valve leaking or even a leak on a pipe somewhere The most common response to this problem may be the expansion vessel If your boiler has been dealing with no problems going back a couple of years, then all of a sudden you notice the water pressure must be topped up once in a while, the chances are the expansion vessel needs checking The expansion vessel is similar to a balloon, as time passes it will loose its pressure and water will enter the vessel, once this happens you may have a boiler breakdown with a fault code displaying on the boiler screen The expansion vessel is a very important part of the boiler and must be maintained every year Another common boiler breakdown is due to dirty water, that is caused when no inhibitor is added to the system water You may have noticed if you've ever vented a radiator that the water is quite dirty as it pertains out from the vent, this normally indicates no inhibitor within the machine, even though inhibitor was added, overtime it'll dilute down and can must be topped up, this will be checked every year The dirty water will eventually block up the boiler heat exchanger, this cause the boiler to overheat and head to lockout Maybe you have encounter a boiler breakdown if it is snowing outside even freezing Most boilers nowadays are condensing boilers, and when the boiler is working it produces condense The condense must exit right into a drain, internally is preferable, but sometimes the condense pipe goes to another drain, if this is actually the case the pipe must be protected from the cold with pipe lagging If the condense pipe freeze over, the condense will start to back up into the boiler and finally the boiler will breakdown, with a fault code displaying on the boiler display These are just a few the most common boiler breakdown faults that could be avoided if only you had the boiler serviced Boilers do breakdown even though serviced each year, but not just as much as a boiler not serviced Always have your boiler serviced every year by way of a Gas Safe Registered company, don't use Joe Bloggs from later on just because he is cheaper All Gas Safe Engineers have to re-sit their gas exams every five years in order to carry on working within the gas industry I hope this advice can help you in keeping your boiler working and producing all of the heat and warm water you need
