Boiler Breakdown Advice

Boiler Breakdown Advice

I have listed some of the most typical boiler breakdown problems below to help you get the boiler backup and working.

You wake up one morning expecting to jump in the shower and then find you have no hot water, you go and check the boiler and notice a fault code is showing on the display, so what do you do?

You need to find out what the fault code is and why it has made the boiler breakdown.

All boilers are given a users manual, inside this manual will be listed all of the fault codes and the reason behind the code to display.

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

Sometimes it's a magic pill simply by pushing the reset button, other times it can be a bit more involved.

Most boiler breakdown fault codes could be avoided just by maintaining your boiler regularly.

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


A boiler can be like a car engine, if left un-serviced it is going to breakdown and could possibly be costly to correct.

One of the most common boiler problems is low water pressure, this is due to the water within the entire system dropping to a spot where in fact the boiler sensor senses low water and throws up a fault code and locks the boiler out.

Low water pressure often means many things, it could be a leak somewhere on the system, a radiator valve leaking or even a leak on a pipe somewhere.

The most common answer to this problem is the expansion vessel. If your boiler has been dealing with no problems going back after some duration, then all of a sudden you see the water pressure should 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 really a very important area of the boiler and needs to be maintained every year.

Another common boiler breakdown is due to dirty water, this is caused when no inhibitor is put into the system water.

You could have noticed if you have ever vented a radiator that the water is quite dirty when it comes out from the vent, this normally indicates no inhibitor within the system, even if inhibitor was added, overtime it'll dilute down and will need to be topped up, this should 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.

Perhaps you have encounter a boiler breakdown if it is snowing outside even freezing?

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

The condense needs to exit into a drain, internally is preferable, but sometimes the condense pipe goes to an outside drain, if this is the case the pipe must be protected from the cold with pipe lagging.

Should the condense pipe freeze over, the condense will start to back up in to the boiler and finally 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 when serviced each year, however, not as much as a boiler not serviced.

Will have  Boiler repairs Middlesbrough  by way of a Gas Safe Registered company, avoid Joe Bloggs from later on just because he is 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 keeping in mind your boiler working and producing all of the heat and warm water you need.
