Best Buy for the ninth consecutive year. It’s pretty clear that Worcester Bosch boilers are rated highly, but that’s not to say that they aren’t susceptible to faults as they get old.
Any boiler can breakdown or run into trouble, regardless of the build quality. When it comes to Worcester Bosch boiler faults, some issues are minor and don’t require the help of a professional, whereas others will need a Gas Safe registered engineer to carry out repairs. In this guide, we talk about common Worcester Bosch boiler problems and the best way to deal with each of them.
Common Worcester Bosch Boiler Problems
- No hot water
There’s nothing worse than finding you have no hot water coming from your taps just as you’re about to jump in the shower or bath. Several things could cause this to happen, such as an issue with your thermostat, a broken diaphragm or a faulty, airlock, motorised valve or heating pump.
How to deal with it: The only thing you can really do is check the thermostat and boiler pressure, as you may find they need to be reset. If all looks good or you still have no hot water once both are set correctly, you’ll have to call in a Gas Safe engineer.
- Boiler keeps cutting out
A blocked or frozen condensate pipe is a very common cause of this issue and will prompt your boiler to display a Worcester Bosch fault code. You’ll know for sure if the pipe is blocked should the boiler make strange noises when it tries to fire up after you’ve pushed the reset button.
How to deal with it: If it’s quite cold outside, your pipe could be frozen. You can pour some warm (not boiling) water over the pipe to thaw it out and then reset the boiler to clear the fault code. However, it could be that your water pressure is low, so you may have to get in touch with your water provider. Don’t forget to check the thermostat as well. If you still experience problems after thawing out the pipe and checking all of the above, you’ll need to contact a qualified engineer.
- Boiler is losing pressure
Low boiler pressure could be a sign that you have a leak somewhere on your central heating system, but it may be that your pressure relief valve is broken. This may also be causing your boiler to turn itself off.
How to deal with it: The first thing you must check is the pressure gauge. If the needle is below 1, you’ll need to re-pressurise your boiler. You can look at your boiler manual to find out the correct pressure level for your system. If this isn’t the cause of the problem, check your boiler and radiators for leaks. Should you find a leak, call a Gas Safe engineer immediately.
- Boiler is dripping or leaking
If your boiler is dripping or leaking, it’s likely that one of the boiler components is broken. Having said that, leaks can be caused by high water pressure or a loose connection.
How to deal with it: As it is dangerous for an unqualified individual to attempt to fix a leaking boiler, you must seek professional assistance right away. Remember, a leaking boiler is often connected to low pressure, meaning your system will be unable to heat your home.
- Strange or loud noises
Whether it be banging or clanking sounds, a boiler that makes strange or loud noises is usually warning you that there is a build-up of limescale somewhere in your system. Noises such as these are often called ‘kettling.’ Boiler kettling can also be caused by air in the system or a faulty pump.
How to deal with it: You can bleed your radiators to try and remove any air and limescale. More often than not, a powerflush is the only solution for getting rid of limescale, so you might have to call in a professional engineer. A powerflush will remove any dirt and debris that has built up over time and usually takes between 5 and 8 hours to complete. If your pump is the issue here, you’ll need a Gas Safe engineer.
- Boiler won’t ignite
There are lots of different things that can stop a boiler from igniting including a fault with the gas valve, insufficient gas pressure, a broken thermocouple and ignition lead problems.
How to deal with it: Check to see if your other gas appliances are working because, if they’re not, it may be something to do with your gas supply, rather than the boiler. No gas coming into your home? Then you’ll need to contact your gas supplier. If gas is entering the house and your boiler is failing to ignite, it’s best to get in touch with a Gas Safe engineer who can quickly and safely determine where the problem lies.
