Signs of a Broken Boiler

A busted boiler is never a welcome sight and often sends homeowners and tenants into complete meltdown, as they have no idea what to do. Fortunately, I’ve decided to create this list and discuss these 5 signs of a broken boiler to help you out.

. . . But how do you know it’s broken?

Signs of a Broken Boiler

A central heating boiler will usually give you a few indications that it’s either on its last legs or in desperate need of repair. Take the time to read through this article to identify 5 common tell-tale signs that your boiler could be about to go bust.

Constant Noise and Unwanted Racket . . .

There’s nothing worse than trying to sit down, relax and watch your favourite TV show when your boiler is making a hell of a noise in the background. But it could be trying to tell you something.

If your boiler has a broken heat exchanger, then it will make a lot of noise.

The sounds you’ll hear are referred to as “kettling” by heating technicians. Sound such as banging, rattling and hissing could be symptoms of lime scale damage within the heating system.

You’ll need to get a local heating engineer to carry out a boiler repair in Woburn Sands and potentially replace the heat exchanger.

Boiler Making Noise

Smell Gas? Turn Everything Off and Leave . . .

If you notice a strange smell near your gas appliances then it could be a sign of an internal gas leak. Appliances such as boilers leak a potentially fatal gas called Carbon Monoxide (CO).

CO is known as a silent killer because it’s difficult to diagnose. If you ever smell gas, especially near your boiler, do the following:

  • Switch off your appliances
  • Avoid any form of ignition (Yes – people do still try to smoke)
  • Open doors and windows before calling an emergency engineer

Corroded Internal Parts . . .

OK so you probably won’t notice that there is anything wrong with the inside of your boiler unless you have it serviced regularly or a fault code appears. This is another reason to have a boiler service completed regularly.

If you do have signs of corrosion within the little white box, then it could be a sign of a water leak or even damp building up inside the casing. Most parts that become corroded can be replaced, but there’s a cost.

Many people consider a new boiler installation in Milton Keynes, especially if their existing warranty has expired.

Loss of Power and Constantly Shutting Down . . .

As with anything, if it’s regularly shutting down or losing power, it’s usually a sign that there’s something wrong.

A boiler will usually lose power when the following occurs:

  • Condensate pipework is frozen
  • Low water pressure
  • Faulty pump
  • Air in the heating system

Its best to have a professional diagnose the issues and take note of any fault codes to help them. If you can provide the engineer with as much detail prior to their arrival, then they’ll have a greater chance of diagnosing the problem before its too late.

Low Pressure on Boiler

Low or Drop in Pressure . . .

A drop in pressure happens frequently with boilers. Most of the time, the repairs needed are relatively straightforward and can be completed by you.

If you suspect a drop in pressure, check the pressure gauge on your boiler. If you notice that the pressure has fallen below 1, then you have a problem and it needs to be addressed.

Most pressure drops are as a result of a water leak or a faulty PRV (Pressure Relief Valve). If the pressure does drop, then your boiler may not work properly and you could notice things such as no hot water or even no central heating.

If the pressure gauge has dropped, the first thing you need to do is check for signs of a physical water leak. Simply open up the boilers casing and look for corrosion or leaking pipework.

If there is no sign of a leak – try repressurising the system by using your manufacturers handbook. If that fails, contact a gas engineer to assess the system.
