5. Installation Guide
Replacing the change over valve hose requires careful disassembly and reassembly of parts within the vacuum's ball mechanism. It is recommended to consult a visual guide, such as a repair video, if you are unfamiliar with internal vacuum repairs. Tools typically required include Torx screwdrivers.
- Prepare the Vacuum:
- Unplug the Dyson DC40 vacuum cleaner from the power outlet.
- Lay the vacuum flat on a clean, stable surface, preferably with the cleaner head facing upwards.
- Access the Ball Mechanism:
- Locate and remove the screws securing the outer casing of the ball mechanism. These are typically Torx screws.
- Carefully separate the two halves of the ball casing to expose the internal components.
- Locate the Old Hose:
- Identify the existing change over valve hose. It is usually a flexible, corrugated hose connecting different sections within the ball.
- Note its orientation and how it connects to the various ports.
- Remove the Old Hose:
- Gently disconnect the ends of the old hose from their respective ports. This may involve releasing clips or carefully pulling the hose ends off.
- Remove the entire old hose from the vacuum.
- Install the New Hose:
- Take the new Dyson Genuine DC40 Change Over Valve Hose.
- Carefully connect one end of the new hose to its corresponding port, ensuring a secure and airtight fit.
- Route the hose correctly within the ball mechanism, matching the path of the old hose.
- Connect the other end of the hose to its port, again ensuring a tight seal.
- Verify that the hose is not kinked or pinched and that all connections are firm.
- Reassemble the Vacuum:
- Carefully align and reattach the two halves of the ball casing. Ensure no wires or other components are pinched.
- Replace all screws and tighten them securely, but do not overtighten.
- Ensure all external covers and components are properly reattached.
- Test Functionality:
- Plug the vacuum cleaner back into the power outlet.
- Turn on the vacuum and test both the main cleaner head and the accessory tools to ensure proper suction and airflow redirection.
- Listen for any unusual noises or air leaks.

6. Operation
Once the new change over valve hose is correctly installed, your Dyson DC40 vacuum cleaner should operate as intended, providing efficient suction for both floor cleaning and when using attachments. The hose automatically redirects airflow when you switch between the main cleaner head and the wand/accessory tools. No specific operational steps are required for the hose itself beyond ensuring it is properly installed.
7. Maintenance
The change over valve hose is designed for durability, but periodic inspection can help prolong its lifespan and maintain vacuum performance:
- Visual Inspection: Periodically inspect the hose for any signs of wear, cracks, tears, or punctures. If accessible, check the internal hose for damage.
- Check Connections: Ensure that the hose connections remain secure and airtight. Loose connections can lead to a loss of suction.
- Clear Blockages: If you experience a sudden loss of suction, check for blockages within the hose. Disconnect the hose (following safety guidelines) and clear any debris.
- Cleaning: The hose generally does not require cleaning. If it becomes excessively dirty, wipe the exterior with a damp cloth. Do not immerse the hose in water.
8. Troubleshooting
If you experience issues after installing the new change over valve hose, refer to the table below for common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Loss of suction | Hose not securely connected; hose kinked or pinched; blockage in hose. | Ensure both ends of the hose are firmly attached. Check for proper routing and clear any visible blockages. |
| Air leaks | Improperly seated hose connections; damaged hose. | Re-check all connections for a tight seal. Inspect the hose for any tears or holes. If damaged, replace the hose. |
| Vacuum not switching between modes (floor/tools) | Hose incorrectly installed or obstructed; issue with the change over valve mechanism itself. | Verify the hose is installed correctly and not impeding the valve's movement. If the problem persists, the valve mechanism may require further inspection or professional service. |
