What does the 30 fault code mean on my Intergas boiler
When your Intergas boiler develops a problem, it will display a fault code on the display panel. In the case of fault code 30, the problem lies with the gas valve.
As the problem here is gas related, the boiler is going to lock out as a safety precaution; your boiler won’t work without the problem being found, fixed and your boiler being reset.
Is a boiler with a gas valve problem dangerous
Any fault that relates to gas, could potentially be dangerous. So, you should call an emergency Gas Safe company as soon as possible. And, if you do smell gas, turn off your gas at the mains until your boiler repair engineer arrives.
If I reset my boiler, will this fix the problem
Don’t attempt to fix your boiler without consulting a Gas Safe engineer, and that includes resetting the appliance. The reason the reset function is integrated into boilers, is so it can be used once the appliance has been fixed. It’s not a way to fix a problem with modern gas boilers.
A reset could trick your boiler into working, even if just for a few minutes. And, if there’s a problem with the gas supply, or the valve is leaking, this could be dangerous. So, leave the repair to a qualified professional.
After seeing fault code 30 on the display panel, what is my boiler repair company going to look out for
The first thing your boiler repair company is going to look for, is a problem with the relay on the gas valve. A faulty relay is the most common reason that fault code 30 is displayed on Intergas boilers.
If the relay on the gas valve isn’t to blame, your boiler engineer is going to need to check the:
- Adjustment on the gas valve is correct
- Valve isn’t sticking partially open or closed
- Wiring and connections to and from the valve are in good condition
- Valve isn’t completely faulty, meaning a replacement is needed
- Printed circuit board (PCB) is fully functional
What does the adjustment on the gas valve have to do with the boiler’s operation
The gas valve on your Intergas boiler has an important role; to control the flow of gas to the burner. However, if the adjustment on the valve is incorrect, the burner won’t be able to get the gas it needs to work efficiently. This is going to result in a weak or non-existent flame, and eventually, your boiler locking out.
So, your boiler repair company needs to check that under normal operation, the valve is providing enough gas to the burner. If it’s not, it needs to be adjusted accordingly, ensuring that the burner is getting all the gas it needs.
Why would the valve on my Intergas boiler be sticking
It’s not uncommon for gas valves on boilers to start sticking. These are mechanical components, and over time they can wear. And, when they do wear, they’ll start to operate much less smoothly. Eventually, this leads to a valve sticking.
When a valve sticks, it could either:
- Stick partially closed, meaning even when maximum gas is called for by the PCB, it’s not being supplied by the valve
- Stick partially open, meaning when the PCB tells the boiler to shut down the gas supply, some gas is still entering the burner when it shouldn’t be
Can my boiler repair company fix a sticking gas valve, or will it need to be replaced
If the gas valve on your boiler isn’t in terrible condition, it’s likely your boiler engineer will be able to fix it. But first, they’ll want to assess its overall condition. They’ll check the wiring and connections to and from the valve, ensuring that there are no electronics that are likely to break in the future.
All being well, they’ll be able to free your gas valve, rather than replace it. However, they’ll want to be confident that this isn’t a problem that’s going to happen again. As this is an issue that relates to gas, there’s an aspect of safety involved. If the valve isn’t in excellent condition, it’s likely they’ll suggest replacing the valve altogether.
How will my boiler engineer know if the wiring and connections to the valve are causing the problem
If adjusting or freeing the valve doesn’t fix the problem, your boiler engineer will want to test the electrical integrity of the wiring and connections to and from the valve. After all, if there’s a problem here, the valve won’t be able to communicate effectively with the PCB. And, that’s going to mean that the signals being received by the PCB are intermittent, and the boiler’s operation will be too.
To test the wiring and connections on your gas valve, your boiler engineer will start with a basic visual inspection. That includes checking for damaged wires or burnt out and loose connections.
If a visual inspection doesn’t show any problems, they’ll need to do a more detailed test. This involves testing each electrical wire and connection using a multi-meter. The multi-meter will show any wire or connection that has low or no power. These issues will need to be fixed before resetting the boiler, clearing the 30 fault code from the display panel.
If the gas valve on my Intergas boiler is faulty, how will my boiler engineer know
If none of the above checks show up any problems, your emergency Gas Safe repair company will need to focus their energy on the valve itself. Like the wires and connections to the valve, the valve can be tested using a multi-meter.
The multi-meter test will show whether the valve is the problem, rather than these wires or connections. And, if it is the valve that’s showing no sign of power, it’s going to need to be replaced to fix the problem. On some occasions, there is a quick fix. However, with the boiler apart and money already spent on labour, it makes sense to replace the valve, rather than doing a temporary fix.
If the gas valve on my Intergas boiler is faulty, how much is it going to cost to fix
If your boiler engineer decides that a replacement gas valve replacement gas valve is in order, it’s likely to cost around £300; that’s including parts and labour.
The job isn’t a complex or long-winded one and would usually take less than one working day. However, bear in mind your boiler repair company may not have a valve handy on their van. They may need to order one in from their local supplier, meaning the timeline for the repair could be 2-3 days in total.
What does the PCB have to do with fault code 30 being shown on my Intergas boiler
Whilst your boiler engineer is going to focus their attention on the gas valve, the valve isn’t always the problem. After checking all wires, connections, ensuring the valve isn’t sticking and testing the electrical integrity of the valve, they’ll focus their attention on the PCB.
The PCB is the component that gives and receives signals to all components in your boiler. It also determines what fault codes should be shown on the display panel and when. If the PCB was to be faulty, the code could be incorrect.
If your PCB is at fault, it’s likely you’ll have noticed the boiler working sporadically of late. This might include things like:
- Turning on and off at random
- Not getting heating or hot water up to temperature
- LED lights flickering on the display
- Controls on the boiler not responding
If this sounds like your boiler, your repair company will be able to test it using a multi-meter, to ensure that this isn’t the problem.
If I need a new PCB for my Intergas boiler, how much is it going to cost
Depending on the exact model of Intergas boiler you own, you should expect to pay around £450 for a PCB replacement. Like the gas valve, it’s unlikely your engineer will have one on their van, so will need to order one in from a local supplier (usually next day delivery).
What could have caused the PCB and/or gas valve to fail
Not including old age, one of the biggest killers of modern boilers, is water damage. So, if your boiler is relatively new and you’re already replacing the PCB and/or gas valve, it might be worth getting your boiler repair company to investigate further.
Water damage comes from internal boiler leaks. This could be a loose connection to a component, leaking pump seals, or even a broken heat exchanger. Whatever the cause of the leak, it doesn’t need to be particularly big in order to cause major problems.
By ensuring you find and fix any leaks, you’ll be reducing the chance of needing similar repairs in the future, not to mention protecting other important boiler components from water damage.
