3 Common Boiler Problems That Require Repair

Mahon Plumbing Common Boiler Problems

If you’re having an issue with your boiler, it could be due to one of these common boiler problems and need repairs.

Your boiler not working is an inconvenience. Fortunately, many modern boilers also display a digital boiler error code to let you know what’s causing the issue problems are common, and a professional can repair them. Here is a look at five common boiler problems that require repair. 

Hot Water Without Central Heating

A boiler should provide central heating and domestic hot water to your home. If you discover that you’re getting hot water from the traps without central heating, you might have to double-check your thermostat settings. Thermostats allow you to control the central heat’s temperature and what time it operates. 

Another thing to consider is the boiler pressure. Boiler pressure describes the pressure of the hot water running through the central heating system. The central heating won’t work if the boiler pressure is too low. You can increase the boiler pressure if you feel comfortable doing so yourself. However, calling a professional is always better to be safe than sorry. 

If your thermostat and boiler pressure are both fine, there could be a problem requiring a professional repair. Other reasons could be broken diaphragms and airlocks or failed motorized valves. There could also be an issue with the diverter valve (opens or closes to direct hot water to the radiators or hot water outlets). If the diverter valve becomes stuck, you might receive hot water with no heating. 

No Heat OR Hot Water

You should be able to trust your boiler to offer your home hot water and heating. If your boiler is receiving power, look at the error code to help determine the problem’s source. Possible issues include the following: 

  • Lack of fuel: If you have a gas boiler, ensure fuel is on your property and that your gas supplier is still providing fuel. On the other hand, if you have an oil boiler, ensure that there is more than enough fuel in the storage tank. 
  • Check the thermostat: Check the settings and set the desired temperature higher than the room’s temperature. 
  • The condensate pipe (which brings condensation from your boiler to your outside drain) is frozen and needs thawing
  • Low boiler pressure: Ensure that you have the boiler pressure set to the manufacturer’s instructions (typically between 1 and 2 on the pressure gauge)
  • The pilot light is out: Older boilers have pilot lights (a small flame that always burns before lighting a larger frame when hot water or heating is necessary). If the pilot light goes out, a fire won’t be able to happen.

A Leaking Boiler

A leaking boiler or any mystery puddle in the home always means something is awry. The cause of the leak depends on the water’s source. A broken internal component, like the pump seal or pressure valve, is the most common cause of a leaky boiler. The boiler pressure might be too high if the leak comes from the pressure valve. On the other hand, a pump seal leak indicates that it is worn and needs a replacement. Additionally, there could be corrosion if the leak occurs around the pipes or tank. Otherwise, a poor installation could be the cause of the leaking boiler. 

Either way, you should cause a professional to fix this issue. We advise that you never attempt to fix a leaking boiler yourself.
