Boiler Breakdown Advice

I have listed a few of the most typical boiler breakdown problems below to obtain the boiler backup and working.


You wake up one morning expecting to jump in the shower only to find you haven't any 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 just 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 behind the code to show.

The fault code reason is only a guide on which to check on for, sometimes it can be a mix of problems, but it's a starting place to trace the problem.

Sometimes  Bathroom Fitters Colchester 's a quick fix simply by pushing the reset button, other times it's rather a bit more involved.

Most boiler breakdown fault codes could be avoided just by maintaining your boiler on a regular basis.

All boiler manufactures recommend having a boiler service completed each year to help keep the boiler working as it was designed for.

A boiler is just like an automobile engine, if left un-serviced it will eventually breakdown and could possibly be costly to correct.

The most common boiler problems is low water pressure, that is caused by the water within the entire system dropping to a point where 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 perhaps a leak on a pipe somewhere.

The most common answer to this problem may be the expansion vessel. If your boiler has been dealing with no problems going back a couple of years, then suddenly you see the water pressure must be topped up every now and then, the chances will be the expansion vessel needs checking.

The expansion vessel is similar to a balloon, over time it'll 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 really a very important part of the boiler and must be maintained each year.

Another common boiler breakdown is because of dirty water, that is caused when no inhibitor is put into the system water.

You might have noticed if you've ever vented a radiator that the water is quite dirty when it comes out of the vent, this normally indicates no inhibitor within the machine, even though inhibitor was added, overtime it will dilute down and can need to be topped up, this will be checked each year.

The dirty water will eventually block up the boiler heat exchanger, this cause the boiler to overheat and head to lockout.

Have you ever encounter a boiler breakdown if it is snowing outside even freezing?

Most boilers these days are condensing boilers, so when the boiler is working it produces condense.

The condense must exit into a drain, internally is preferable, but sometimes the condense pipe would go to another drain, if this is the case the pipe has to be protected from the cold with pipe lagging.

Should the condense pipe freeze over, the condense will start to back up into the boiler and eventually the boiler will breakdown, with a fault code displaying on the boiler display.

These are just a few the most frequent boiler breakdown faults that may be avoided if only you'd the boiler serviced.

Boilers do breakdown even though serviced each year, but not just as much as a boiler not serviced.

Will have your boiler serviced each year by a Gas Safe Registered company, avoid Joe Bloggs from later on just because he could be cheaper.

All Gas Safe Engineers need to re-sit their gas exams every five years to keep 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.
