Common Boiler Breakdown Problems
I have listed a few of the most common boiler breakdown problems below to help get the boiler back up and working.
- You wake up one morning expecting to jump in the shower only to find you have no hot water.
You 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 supplied with a users manual.
- inside the manual will be listed all the fault codes, the reason for the code to display.
The fault code reason is only a guide on what to check for.
- Sometimes it can be a combination of problems, but it’s a starting point to try and trace the problem.
- Sometimes it’s a quick fix just by pushing the reset button.
- Other times it can be a bit more involved.
- Most boiler breakdown fault codes can be avoided.
Just by maintaining your boiler on a regular basis.
- All boiler manufactures recommend having a boiler service carried out each year.
- To keep the boiler working as it was designed for.
- A boiler is just like a car engine, if left un-serviced, it will eventually breakdown.
- It could possibly be costly to repair.
One of the most common boiler problems is low water pressure.
- This is caused by the water within the whole of the system dropping.
- The pressure drops to a point where the boiler sensor senses low water.
- Then throws up a fault code that locks the boiler out.
Low water pressure can mean many things.
- it could be a leak somewhere on the system.
- Radiator valves leaking even a leak on a pipe somewhere.
The most common answer to this problem is the expansion vessel.
- If your boiler has been working with no problems for the last couple of years.
- Then all of a sudden you notice the water pressure needs to be topped up every now and then.
The chances are the expansion vessel needs checking.
- The expansion vessel is like a balloon.
- Over time it will lose 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.
- It needs to be maintained each year.
- Another common boiler breakdown is dirty water.
- This is caused when no inhibitor is added to the system water.
You may have noticed if you have ever vented a radiator.
- The water is very dirty when it comes out of the vent.
- This normally indicates no inhibitor within the system, even if the inhibitor was added.
- Over time it will dilute down and lose its protection, it will need to be topped up.
- It needs to be checked every year without fail.
The dirty water will eventually block up the boiler heat exchanger,
- This will cause the boiler to overheat and go to lockout.
- Have you ever encounter a boiler breakdown when it’s snowing outside even freezing?
- Most boilers these days are condensing boilers, and when the boiler is working it produces condense.
The condense needs to exit into a drain, internally is preferable.
- Sometimes the condense pipe goes to an outside drain.
- If this is the case the pipe needs to be protected from the cold with pipe lagging.
- Should the condense pipe freeze over.
- Condense will start to back up into the boiler, and eventually, the boiler will breakdown.
- A fault code will be displayed on the boiler display.
- These are just a couple of the most common boiler breakdown faults that could be avoided,
If only you had the boiler serviced.
- Boilers do breakdown even when serviced each year.
- Not as much as a boiler not serviced.
- Always have your boiler serviced each year by a Gas Safe Registered company.
- Don’t use Joe Bloggs from down the road just because he is cheaper.
- All Gas Safe Engineers have to re-sit their gas exams every five years to be able to carry on working within the gas industry.
- I hope this advice helps you in keeping your boiler working and
- producing all the heat and hot water you need.
