Troubleshooting Common Issues
This section addresses typical problems with the Ideal Logic Combi 24, including ignition failures, low pressure, and error codes – consult the PDF.
Boiler Not Igniting
If your Ideal Logic Combi 24 fails to ignite, several factors could be at play. First, verify the gas supply is active and the boiler is receiving gas. Check the electrical connection; ensure the unit is properly powered on. A common issue involves the ignition sequence – listen for clicking sounds, indicating an attempt to ignite.
If no clicking is heard, the ignition components may be faulty. Low gas pressure can also prevent ignition, requiring a qualified gas engineer to investigate. Refer to the PDF manual for specific error codes displayed on the control panel, as these pinpoint the problem. Resetting the boiler might resolve temporary issues, but persistent failures necessitate professional attention. Always prioritize safety and avoid attempting repairs yourself.
Low Water Pressure Problems
Experiencing low water pressure with your Ideal Logic Combi 24 can stem from several causes. Initially, check all taps and valves throughout your home to ensure they are fully open. A partially closed valve restricts flow. Inspect the boiler pressure gauge; it should ideally be between 1 and 1.5 bar. If below 1 bar, you’ll need to repressurize the system – consult the PDF manual for detailed instructions.
Air trapped within the system can also mimic low pressure. Bleed the radiators to release any trapped air. Persistent low pressure might indicate a leak somewhere in the system, requiring a qualified heating engineer to locate and repair it. Ignoring this issue can lead to boiler inefficiency or failure.
Error Codes and Their Meanings
The Ideal Logic Combi 24 utilizes error codes to diagnose issues. These codes appear on the control panel, signaling specific problems. A flashing light accompanied by a number indicates a fault. For example, a code relating to ignition failure suggests a gas supply issue or faulty ignition component. Refer to the comprehensive PDF manual for a complete list of error codes and their corresponding solutions.
Common codes include those related to low water pressure, overheating, or flame detection errors. Attempting repairs based solely on the code is discouraged; always consult a qualified heating engineer for complex issues. Ignoring error codes can lead to further damage.

Maintenance and Care
Regular servicing is crucial for the Ideal Logic Combi 24. Cleaning and scale reduction, alongside water treatment, ensure optimal efficiency and longevity.
Regular Servicing Requirements
Annual servicing by a Gas Safe registered engineer is essential for maintaining the Ideal Logic Combi 24’s efficiency and safety. This involves a comprehensive inspection of all components, including the burner, flue, and gas supply.
The engineer will check for gas leaks, ensure proper combustion, and verify the functionality of safety devices like the carbon monoxide detector. Regular servicing helps prevent potential faults, extends the boiler’s lifespan, and ensures compliance with warranty requirements.
Ignoring servicing can lead to reduced performance, increased energy bills, and potentially dangerous situations. Keep a record of all servicing carried out, including dates and engineer details, for future reference and warranty claims.
Cleaning the Boiler
External cleaning of the Ideal Logic Combi 24 should be carried out periodically with a damp cloth to remove dust and debris; Do not use abrasive cleaners or solvents, as these can damage the casing. Ensure the boiler is switched off and cool before cleaning.
The internal components require professional cleaning during servicing. A qualified engineer will remove any scale or build-up from the heat exchanger, ensuring optimal performance and efficiency. Attempting to clean internal parts yourself is dangerous and will invalidate the warranty.
Regular professional cleaning contributes to a longer boiler lifespan and prevents potential issues related to overheating or reduced water flow.
Scale Reduction and Water Treatment
Scale build-up within the Ideal Logic Combi 24 can significantly reduce efficiency and potentially cause component failure. Water treatment is crucial, especially in hard water areas. Consider installing a scale reducer or utilizing a water softening system to minimize scale formation.
Regular flushing of the system, performed by a qualified engineer during servicing, helps remove existing scale. Chemical inhibitors can also be added to the system water to prevent future scale accumulation. Ignoring scale build-up will lead to reduced performance and costly repairs.
Consult a professional for advice on the most suitable water treatment solution for your specific water hardness level.
