HOW TO FIX A BOILER THAT’S STOPPED WORKING
PLEASE NOTE: It is illegal to work on a gas boiler if you are not qualified to do so. Never remove the casing to your boiler for access, or do work on anything to do with gas pipes, the boiler or the flue! The advice below does not involve working on your boiler and instructions for re-pressurising can be found in your manual.
Boiler Stopped Working? here is a tip that might get you going… Before you call a plumber it may be worth checking out the following points and save you money!
There are so many things that can go wrong with a boiler and stop it from working. But here are a couple of simple problems that a householder can sort out without calling out an engineer.
The first one occurs if you have a ‘systems’ boiler where the central heating water is sealed in a closed circuit. The circuit is filled by mains water via a filling loop. The boiler will have a pressure gauge and it should read 1.25bar to 1.5bar when cold. However if you have lost pressure and it is below 0.5bar then the boiler will stop working. It has a low water detector and display an error code. The solution is to refill the system via the filling loop to 1.25bar and restart the boiler.
The second simple, yet common problem happens with condensing boilers during very cold spells. If the condense pipe leaves the boiler and passes through the wall to the outside, ice can block it. If this happens then the boiler will stop working. Try warming the outside condense pipe with hot water to free the ice and then restart the boiler.
GOOD LUCK 🙂
