A Step-by-Step Guide to Carrying Out a Strip Down Boiler Service to a Worcester Bosch CDi Classic

Maintaining a Worcester Bosch CDi Classic boiler is key to ensuring it runs smoothly and efficiently. By performing a strip down boiler service on your boiler, you can be sure the components are regularly checked, reducing the risk of costly breakdowns. Here’s a step-by-step guide to performing a strip down boiler service on a Worcester Bosch CDi Classic. 

1. Gather the Tools and Protective Wear: Before you start the strip down boiler service, ensure you have the right tools and protective wear. You’ll need safety goggles, protective gloves, a spanner, a screwdriver and a toolkit.

2. Isolate the Power: Before you start your strip down boiler service, switch off the power from the main source and disconnect from the mains supply. This will prevent any electrics from triggering during the strip down process.

3. Remove the Outer Cover: Using the screwdriver, gently unscrew the screws securing the outer cover, making sure to keep them safe for re-attaching the cover once the service is complete.

4. Disconnect and Remove the Extractor Fan: In order to remove the extractor fan, the fastenings must first be undone and then disconnected from the electrical connection. 

5. Inspect the Components: Once the extractor fan is removed, you’ll be able to inspect the components and parts of the boiler, such as the spark electrode, the condensate trap, the heat exchanger and the air intake chamber. Check these components and replace any that are worn or damaged.

6. Reassemble the Parts: Once all of the boiler components have been inspected and replaced, the extractor fan can be re-attached and the outer cover re-secured in place.

7. Test the Boiler: Before completing the strip down boiler service, switch the power back on and check that the boiler is working properly. Test the boiler at full capacity and check that the programming is still functioning correctly.

By following these steps, you can be sure that your Worcester Bosch CDi Classic boiler is running as it should. Regularly servicing and maintaining your boiler not only prolongs its life, but also ensures it’s running at its most efficient
