Main Combi 24 HE luke water


I have an issue with my Main Combi boiler. It is 24 HE model and instead of providing hot it provides very luke warm water. On the top of it I can see that boiler itself is pretty heavily leaking from the bottom. What is wrong? Can I repair it myself?



Hi Jack

Your problem can be easily resolved by replacing flow switch. You don’t have to drain system to do this, however if you have no experience with boiler parts replacement it is better if you call for boiler specialist
