3 Common Boiler Issues, The Likelihood of Experiencing Them And Their Repair Costs A malfunctioning boiler is always an inconvenience. Luckily, many boiler problems are common and can be fixed by a professional heating engineer. Modern boilers show a digital boiler error code to make it easy to figure out what the problem is. 1. Hot water, no heat If your thermostat is working and the boiler pressure is high enough, but you have no central heating, it's time to call a professional (a Worcester Bosch service if you are using a Worcester Bosch boiler). A Gas Safe registered engineer is qualified to identify faulty diaphragms and airlocks, motorised valves or diverter valves. They can also perform the necessary repairs if needed or replace any broken parts. 2. No heat and no hot water Look at the error code displayed to find out what the problem is. Some common issues include:

fuel/oil.
You may need to adjust the thermostat. Try setting it a few degrees above the current room temperature.
The condensate pipe is frozen and needs to be thawed.
The boiler pressure is set too low. Adjust it according to the manufacturer's instructions.
If your boiler is older, it will likely have a pilot light. This is a small flame that burns continuously before igniting a larger flame when heat or hot water is required. If the pilot light goes out, then the boiler won't be able to function.
3. Leaking boiler A boiler leak is usually indicative of a larger problem. The source of the leak will help identify the issue. Before trying to find the source of the leak, turn off the central heating and stop the water supply. The primary culprit of a boiler leak is usually internal damage, such as a broken pump seal or pressure valve. If the source of the leak is the pressure valve, then the boiler may have too much pressure. A leaking pump seal, on the other hand, needs to be replaced as it has worn out. If your boiler is leaking water around the pipes or tank, it's likely due to corrosion. It might also be from a poor installation. In either case, you need to call a professional Gas Safe registered engineerto figure out the problem and fix the leak. How much does it cost to repair a boiler?
