Worcester GREENSTAR-36CDI-COMPACT user manual

There could be several reasons why your Worcester Greenstar 36cdi Compact boiler is not firing up. Here are a few common issues to check:
1. Lack of Gas Supply: Ensure that the gas supply to the boiler is turned on and the gas valve is open. Check other gas appliances in your home to see if they are working, as it could be an issue with the gas supply to your property.
2. Power Supply: Check if the boiler has power and that it is receiving electricity. Make sure the circuit breaker or fuse for the boiler is not tripped.
3. Thermostat Settings: Verify that the thermostat is set to a temperature higher than the current room temperature. If it's a programmable thermostat, check the programmed schedule as well.
4. Low Water Pressure: Low water pressure in the central heating system can prevent the boiler from firing up. Ensure that the water pressure gauge on the boiler reads within the recommended range (usually between 1 and 1.5 bar). If it's too low, try repressurizing the system following the manufacturer's instructions.
5. Blocked Condensate Pipe: The condensate pipe carries acidic water produced by the boiler to a drain. If this pipe becomes blocked or frozen, it can trigger a safety feature that prevents the boiler from firing up. Inspect the pipe for obstructions and clear any debris or ice buildup.
6. Faulty Ignition System: If the boiler has an ignition problem, it might not be able to start the combustion process. In this case, it's best to contact a qualified heating engineer to diagnose and repair the ignition system.
If you have checked these points and your boiler is still not firing up, it's recommended to contact a qualified heating engineer for further assistance.
