Our Top Ten Boiler Faults we come up against:
No Heating or Hot Water
It’s not just low pressure that causes your boiler to fail. Broken pumps, valves, airlocks and controls can all knock out your boiler. Modern boilers give an error code, check this in the manual and then if you can’t fix it yourself, call in a qualified heating engineer.
Banging, Knocking, Gurgling or Whistling
Any off the above noises are tell-tale signs that you have a problem and a boiler breakdown is just round the corner. Low water pressure and air trapped in the system are common causes to check for first. Kettling and bangs could be a sign of impending pump failure or a blocked heat exchanger. You’re better off calling an engineer sooner rather than later for these problems.
Leaks and Weeps
A boiler should not leak anywhere so if you do have a leak, you have cause for concern. If you’re lucky it could just be a leaky filling loop from inside the boiler. Again, recommended action is to call an engineer – PC boards don’t like water and they are expensive to replace. Leaks left alone quite often cause multipul issues with boilers. It might look like a small leak, but you would be surprised how often they cause a completely new boiler change.
No Pilot Light
Quite often a simple fix, try resetting the boiler first. If no joy it is usually a broken thermocouple. A change in the wind quite often knocks the pilot light out or check the boiler has power.
Frozen Condensate Pipe
A modern condensing boiler has to get rid of waste water. Sometimes this pipe freezes up and locks the boiler out. You can try and pour warm water over the external condensate pipe and try resetting the boiler. Hopefully this will work. Please remember if you have this issue so do your neighbours, therefore call outs may be later than normal.
A Condensing Combi Boiler only works if the pressure is above 1 bar. There is usually a gauge on the front of the boiler. When your pressure gauge reads below 1, your boiler will breakdown. Possible reasons for this include a water leak in the boiler or on your radiators, check the TRV’s and valves. Remember every time you bleed your radiators you lose pressure, remember to top it back up. Again, check for a fault code and read the manual, this could be a nice simple fix you can do yourself.
You know the song your kettle makes when you boil it dry, this is called Kettling. It’s usually the result of lime scale or sludge build up on the system’s heat exchanger. The heat exchanger is in the heart of your boiler. When you hear this, you need to call an engineer. They may be able to flush it out or have to quote for a new heat exchanger. The bad news is this is often a point in time to think about changing your broken boiler for a new system.
Thermostat and Control Issues
If you have a wireless room stat or RF stat, the first thing to do is to check your batteries. Some cheaper thermostats can conflict with your neighbour if they are on the same frequency. After that you will need an engineer round to check out your controls.
Radiators not getting warm
If the boiler is working fine, check your pump is working first. Feel your radiators if they are only hot in patches, they are probably suffering from sludge build-up or trapped air. If the bottom of your radiator getting hot but the top is staying cool, the radiator in question probably needs to be bled. If your happy to bleed your radiators great, just remember to top the system back up, repressurize it. Your boiler manual should show you how.
Boiler Cuts out or Turns Off
This is usually a safety device in the boiler, common reasons for this are thermostat issues, water pressure getting low, water flow due to a faulty valve or pump failure. A modern boiler will give you an error code, check for boiler manual. You will need to call out a Gas Safe Engineer for these works, most companies with quote before the works are carried out.
Boiler Maintenance Cover Plans
If you worry about your boiler breaking down, it might be worth looking at Boiler Insurance. Quite often nowadays it is wrapped up with your banking or home insurance; I would just check their service level agreement of these “Free” plans. So check if you have this before you look at any other providers of Maintenance Plans.
