5 Common Ideal Boilers Problems
When choosing a new boiler, most homeowners focus on the benefits and features that each brand has to offer. It’s equally important to check any potential weak points of the boiler brand you settle on, so you’re aware of what to expect.
Life without a boiler is not pretty and neither is a cold shower. That’s why being aware of the most common problems your Ideal boiler is going to suffer is critical in ensuring your boiler downtime is as minimal as possible. At New Boiler Nottingham, we have this quick guide resolving common Ideal boiler problems.
The ignition problem is more common with Ideal combi boilers. Before the failed ignition, you will hear a sparking sound as the boiler is trying to ignite before going into a lockout. An orange light will then turn on the control panel.
The boiler lockout is a safety measure and not necessarily part of the problem. Once the ignition issues have been sorted, the boiler should be able to fire away without any issues.

Cause: Several problems could cause a failed ignition in a boiler. It’s vital to have the boiler problem properly diagnosed to avoid further problems. Some parts to pay close attention to when diagnosing the boiler are the ignition sensors which could be blocked by years of carbon deposits and other debris.
Fix: sometimes, cleaning the sensors can fix the problem. However, if the boiler has been in operation for quite some time, it makes more sense to replace the sensors. Because the boiler has to be stripped down, it’s best to have an engineer come and tend to the boiler.
The boiler is leaking
Boiler leaks are common with all boiler brands given the high-pressure working environment and the abrasive nature of water. As the boiler grows older, it’s more likely to leak. Even though boiler leaks are easy to fix, it’s important to ensure they are repaired promptly. If the leak is left unrepaired, it could lead to other boiler problems like low boiler pressure and might also cause the heat exchanger to fail.
Cause: Seals take the most blame for boiler leaks. As the boiler vibrates, the seal can get loose or fall apart. If you recently adjusted the pressure of the boiler and set it above the recommended limit, the pressure valve can blow out of position to relieve the pressure and prevent further damage to the boiler.
Fix: Before you can try any drastic fixes, first check the heat pump and make sure it has not come loose, which could let water escape. Tightening the pump could stop the leak.
If tightening the pump doesn’t work, then you have to focus on the seal, which means you have to install a new pump which makes more sense. For leaks along pipes, the fix is easier unless the pipework was not installed correctly. If that’s the case, you need to call in a boiler engineer to re-install the pipework.
Loud explosive noise on ignition
Any weird noises coming from your boiler are always a reason for concern. The loud bangs from your boiler during ignition have scared you on more than one occasion. Needless to mention, the banging sounds serious and it could be if it’s not quickly fixed.
This problem is more common in the Icos and Isar range of Ideal boilers, but you might also experience the same challenge with other boiler models as well.
Causes: Boilers attempt to ignite three times. In this case, the boiler fails to ignite in the first and second attempts. When it ignites in the third attempt, there’s a lot of gas that has accumulated in the chamber, which results in the explosion.
Fix: The flame sensor is usually to blame in most cases. It fails to detect the flame and the boiler doesn’t ignite normally. It’s recommended to have a boiler engineer look that the flame sensor and other ignition leads.
After replacing the flame sensor and doing a diagnostic on all the other ignition leads, you need to have another look at everything and ensure the ignition chamber is getting the right amount of gas. Also, ensure you adjust the speed of the fan before you attempt to restart the boiler.
When it comes to matters relating to gas and ignition, it’s best to let an experienced boiler engineer handle the diagnosis and the repairs.
Boiler won’t switch on
This fault might sound very similar to the failed ignition one, but it’s slightly different. Owners of the Isar and Icos Ideal boilers might face this problem more often than users with other types of boilers. When this problem happens, it looks like the boiler has given up. But, the cause of the problem is quite simple and can be fixed.
Cause: Most of the time, the boiler is just having some wiring problems. The PCB is usually the problem. But you can start with other simpler problems like checking the plugs and the sockets to make sure they are not the problem.
If the sockets and plugs check out, you can use a multimeter to check voltage supply throughout the circuit board. Wiring upgrade can get the boiler working properly again.
If that doesn’t work or everything seems fine, you can then resort to checking the PCB. PCBs are complex circuit boards and are the hive of boiler controls. If the PCB fails or has a fault, it’s often better to replace the entire unit.
This boiler fail is often described in many different ways by different homeowners. The only similar description is that it sounds like water trying to escape. In most cases, this will happen when the weather is extremely cold or after the boiler has been in use for a number of years.
The problem doesn’t sound as dangerous as the banging noises, but it’s one that you should ignore.
Cause: The gurgling sounds are often caused by water trying to fit into narrow pipe ways as a result of a blockage. The condensate boiler is often affected in these cases. It can be affected by freezing in cold weather or a buildup of deposits over the years.
Fix: Luckily, the fix here is relatively simple. You have to expose the condensate pipe by removing the strip plate at the bottom of the boiler. Check for any water running out. Remove the condensate pipe trap and clear the blockage. If there are no blockages in sight, you can try thawing the pipe to melt frozen water and restore flow.
Boiler faults are very frustrating and can be quite an inconvenience. But when you know what to expect and what to do when it happens, life is much easier. With these quick faults and possible fixes, it’s easier to manage boiler breakdowns in the easiest and most affordable way possible.
