Troubleshooting and fixing fault code L0d “Ignition Lockout”
on your Ideal Logic2+ Combi Boiler
Hello and welcome to our blog post about the Ideal Logic2+ Combi Boiler’s L0d issue. You’ve come to the right place if your boiler is suffering a “Ignition Lockout.” We will examine the specifics of this fault, its warning signs, troubleshooting advice, and what you can do as a homeowner or engineer to successfully handle the problem in this post.
What is an Ignition Lockout?
The L0d fault code on the Ideal Logic2+ Combi Boiler is an indication of an “Ignition Lockout” issue. When this fault occurs, the boiler fails to ignite, and as a safety measure, the system shuts down to prevent potential hazards. An ignition lockout can happen due to various reasons, such as a lack of fuel supply, an issue with the ignition electrode or flame sensor, or problems with the gas valve or ignition control.
L0d Red Flags!
The boiler repeatedly attempting to ignite but failing
Display showing the L0d fault code or an ignition-related error message
The boiler is making unusual clicking or sparking noises during ignition attempts
Loss of heating and hot water supply in your home

L0d Troubleshooting Tips:
- Check the fuel supply: Ensure that the gas or oil supply to the boiler is not interrupted. Make sure the isolation valve is open and there are no issues with the gas or oil meter.
- Reset the boiler: Sometimes, a simple reset can resolve temporary glitches. Locate the reset button on your boiler and follow the manufacturer’s instructions to perform a reset.
- Inspect the ignition electrode and flame sensor: These components can become dirty or damaged over time, affecting the ignition process. Carefully clean them using a soft cloth or consult a professional for maintenance.
- Check for air in the gas line: Air pockets in the gas line can hinder ignition. Bleeding the gas line or contacting your gas supplier for assistance can help resolve this issue.
- Inspect the condensate pipe: The condensate pipe carries acidic water away from the boiler. If this pipe becomes blocked or frozen, it can trigger an ignition lockout. Check the condensate pipe for any blockages or signs of freezing. If frozen, thaw the pipe using warm water or a suitable method recommended by the manufacturer
- Examine the ventilation: Proper ventilation is essential for the boiler’s efficient operation. Make sure the air vents and flues are clear of any obstructions or debris that could restrict airflow. Blocked ventilation can lead to ignition problems and subsequent lockout
- Verify the thermostat settings: Ensure that the thermostat is set correctly and calling for heat. Sometimes, incorrect thermostat settings can prevent the boiler from igniting. Adjust the temperature settings as needed and check if the boiler responds accordingly.
What can you do as a Homeowner?
- Check the basics: Ensure that the boiler is receiving power, the electrical connections are secure, and the circuit breaker or fuse associated with the boiler is intact. Sometimes, a tripped circuit breaker or power outage can lead to temporary faults.
- Reset the boiler: Locate the reset button on your boiler (refer to the user manual if needed) and perform a reset. This can help clear any temporary glitches or errors in the system. However, keep in mind that repeated resets without addressing the underlying issue may cause further problems, so use this option sparingly.
- Verify the fuel supply: Ensure that the gas supply to the boiler is not interrupted. Check if the isolation valve is open and the gas or oil meter indicates a supply. If you have a gas boiler, check if other gas appliances in your home are working properly to rule out a general gas supply issue.
- Check the boiler pressure: Low boiler pressure can lead to ignition problems. Check the pressure gauge on the boiler and ensure it is within the recommended range as specified in the user manual. If the pressure is low, you may need to repressurize the system.
- Inspect the condensate pipe: Check the condensate pipe for any blockages or signs of freezing. Clear any obstructions and, if frozen, thaw the pipe using warm water or a suitable method recommended by the manufacturer. A blocked or frozen condensate pipe can trigger an ignition lockout.
What to do as a Qualified Gas Engineer?
- Diagnostic testing: Utilise diagnostic tools and equipment to assess the performance of various boiler components. This may include checking the gas supply pressure, testing the ignition electrode and flame sensor, and verifying the functionality of the gas valve and ignition control.
- Check gas pressure and supply: Verify that the gas pressure is within the specified range for the boiler model. If the pressure is too low or inconsistent, investigate and rectify the underlying cause, such as a faulty gas regulator or a problem with the gas supply line.
- Verify electrical connections: Inspect the electrical connections, including wiring, terminals, and control boards. Ensure that all connections are secure and free from damage or corrosion. Repair or replace any faulty electrical components or connections that may be contributing to the ignition lockout.
- Inspect the condensate pipe: Check the condensate pipe for any blockages or restrictions. Remove any debris or obstructions that may be preventing proper drainage. Ensure that the condensate pipe has a suitable fall and is not kinked or damaged.
- Inspect the flue: Check the flue for any blockages, such as debris or bird nests, that may be obstructing proper ventilation. Clear any obstructions and ensure the flue is functioning correctly.
- Check the flue gas outlet: Verify that the flue gas outlet is not blocked or obstructed. Make sure it is installed correctly and in compliance with regulations and manufacturer guidelines.
- Test flue gas analysis: Conduct a flue gas analysis to ensure proper combustion and efficient operation of the boiler. Adjust the combustion settings if necessary to achieve optimal performance and compliance with safety standards.
FAQ's
It is advisable to have your boiler serviced annually by a professional engineer to ensure its efficiency, and safety, and to detect and address any potential issues before they escalate.
Keeping the boiler area clean, ensuring proper ventilation, and regularly checking fuel supply are simple maintenance tasks that can contribute to preventing certain issues. However, major repairs and component replacements should be handled by professionals.
