Locating the Reset Button on Your Ideal Logic Combi 30

The first step in this journey is finding the reset button on your Ideal Logic Combi 30 boiler. This essential component is conveniently located directly below the digital display, easy to spot and access.

In fact, it’s so straightforward that it doesn’t require you to navigate any complex menu settings.

  • Just a simple push on the reset button underneath the display can initiate the reset process.

This easy access to the reset button makes the reset process less daunting, especially when you’re dealing with a boiler that isn’t working as it should.

So the next time your boiler starts throwing tantrums, you know where to start – the reset button underneath the display.

When Should You Consider a Boiler Reset?

So, when exactly should you consider pushing the reset button on your Ideal Logic Combi 30? The answer is relatively straightforward.

If your boiler displays the common Ideal boiler error codes or isn’t providing adequate heating and hot water, it’s time to consider a reset.

Let’s not forget about power outages too. They can disrupt the boiler’s functioning, necessitating a reset. Post-reset, remember to check and reconfigure the boiler’s timers if they have reset to default settings. This small step can help you maintain your hot water schedule without disruptions.

Initiating the Reset Process

Resetting your Ideal Logic Combi 30 is not as complex as it seems.

But before you go about pushing the reset button, it’s crucial to consult the boiler’s user manual. This ensures you’re following the proper procedure and adhering to safety guidelines.

To initiate the reset process, locate the reset button underneath the display.

If your boiler model doesn’t have a dedicated physical reset button, you can perform the reset by turning the control knob to the reset position and then back to your desired setting.

Responding to Ideal Boiler Error Codes

Error codes on your ideal boiler’s display are indicators of specific faults that the boiler’s sensors have detected. These codes such as the Ideal L2 error code or L1 error code can appear during a boiler lockout or after a power cut, and understanding them can help you identify potential issues to address.

The user manual is your best friend here, offering information on each error code. This information aids in troubleshooting and determining the next steps for resolution.

If error messages persist on the boiler’s control panel after attempting a reset, it may indicate more complex issues. In such cases, you might need assistance from the user guide or even a qualified engineer to address the service message.

Adjusting Boiler Pressure

Pressure is a key player in the smooth running of your Ideal Logic Combi 30 boiler. Ideally, the pressure should be around 1.5 bar, as indicated on the boiler’s pressure gauge.

A pressure drop below 1 bar can inhibit boiler operation. In such cases, topping up the system using the filling loop to restore pressure between 1 and 1.5 bar can help.

On the flip side, excessive water pressure above the normal range can trigger the boiler’s safety system to shut down. To prevent this, you can reduce the pressure by bleeding a radiator or draining some water from the system.

After the Reset: What to Expect

Once you’ve successfully reset your Ideal Logic Combi 30 boiler, you should notice a few positive changes. The boiler should ignite and operate normally, clearing any error codes that were present before the reset.

Additionally, the boiler will initiate the ignition sequence again. You should also notice that the boiler shows a status C, indicating that it’s heating water for use in your home’s radiators. This status should remain until the set temperature is achieved, signaling a successful reset.

Troubleshooting Post-Reset Issues

A boiler reset isn’t always a magic bullet. If issues persist after a reset, it may point to more complex problems that need a professional assessment. However, before calling in the big guns, there are some common post-reset issues that you can troubleshoot on your own as a first step.

Remember, safety first! When persistent problems occur or if you’re unsure about any troubleshooting steps, it’s time to contact a Gas Safe registered engineer. Ignoring significant issues, especially after a reset, isn’t a good practice and requires a qualified professional to ensure safety and correct functioning of the boiler.

No Hot Water or Heating

If you’re facing a lack of hot water or heating post-reset, don’t panic! Start by checking if the boiler has power. A lack of visual indicators such as lights or displays may signal an issue with the power supply.

Next, troubleshoot the thermostat by following these steps:

  1. Reset the boiler or replace the thermostat’s batteries to resolve incorrect status display issues.
  2. If central heating is still absent after resetting, ensure that the radiators are turned on.
  3. Check that the thermostat is set correctly and functioning properly.

Sometimes, the diverter valve might be stuck, inhibiting hot water or heating. Fixing or replacing the valve could solve this issue.

Persistent Error Codes

Persistent error codes after a reset can be frustrating. But don’t lose hope just yet. A second reset attempt may clear the error code.

If the display consistently shows status C when heating is off or the set temperature is not met, it could indicate an issue that requires professional assistance.

Serious boiler issues such as the boiler repeatedly switching off, the pilot light going out, or unusual odours should not be ignored. They necessitate contacting a certified engineer.

Regular Maintenance to Prevent Future Resets

Ensuring the longevity and efficiency of your Ideal boiler, such as the Ideal Logic Combi 30 from the newer range, goes beyond just resetting.

This boiler is one of the best combi boilers on the market, so is highly popular, but it still needs looking after.

Regular maintenance performed by a Gas Safe-accredited engineer can significantly increase the boiler’s lifespan and efficiency, making it one of the ideal boilers for homeowners, whether they have a boiler from the older range or the newer range.

Servicing the boiler during warmer seasons can help identify potential faults before the higher demand during colder months.

This proactive approach minimises disruptions and ensures you’re not left out in the cold! Plus, regular servicing is often a requirement of the manufacturer’s warranty, so you wouldn’t want to risk voiding the guarantee.

Regular maintenance not only ensures optimal functioning but also reduces energy costs and carbon footprint.

Maintaining boiler pressure at around 1.5 bar or within the green zone on the pressure gauge is crucial for smooth operation. Regular maintenance also addresses potential system blockages due to built-up sludge, which can cause the boiler to trip.

Expert Intervention: When to Call a Gas Safe Registered Engineer

There comes a time in every boiler’s life when it may require a professional touch. If your boiler doesn’t light after the reset process, it’s advisable to consult a Gas Safe Registered engineer. Complex problems such as:

  • ignition failure
  • leaks
  • pump failures
  • internal electrical issues
  • expansion vessel failures

require the expertise of a Gas Safe registered engineer.

Safety is paramount when dealing with boilers. Combustible materials, high pressure, and electrical components in boilers should be handled by trained professionals.

For boiler repairs involving work with gas, only engineers certified as Gas Safe registered are legally allowed to carry out the work. Remember, certified technicians are equipped to safely and effectively resolve boiler issues, thereby preventing potential risks.


To sum up, resetting your Ideal Logic Combi 30 boiler isn’t rocket science. With a clear understanding of the reset button’s location, the right situations for a reset, and the correct reset process, you’re well-equipped to tackle most boiler issues.

However, don’t forget the importance of regular maintenance and knowing when it’s time to call in a professional.

With a proactive approach, you can significantly extend your boiler’s lifespan and ensure efficient operation, reducing energy costs and contributing to a greener planet. So, the next time your boiler throws a tantrum, remember – you’re armed with knowledge, and you’ve got this!
