Dyson DC40 user manual

There could be several reasons why your Dyson ball might not be spinning. Here are a few possible causes:
1. Clogged brush bar: The brush bar might be clogged with hair, threads, or other debris. Check and remove any blockages from the brush bar, and ensure it rotates freely.
2. Brush bar switch off: Make sure the brush bar switch located on the main body of the vacuum is turned on. If it's off, the brush bar won't spin.
3. Motor or belt issue: The motor that powers the brush bar or the belt that connects the motor to the brush bar might be damaged or worn out. You may need to replace the motor or belt if this is the case.
4. Blockages in the airway: Check for clogs or blockages in the vacuum's airway, including the hose and wand. If there's reduced suction, it can affect the brush bar's performance.
5. Overheating: If the vacuum's motor overheats, it may shut off the brush bar to protect itself. In this case, let the vacuum cool down for a while before using it again.
If none of these solutions resolve the issue, it's best to contact Dyson customer support or take the vacuum to an authorized service center for further assistance.

The "GREY" button on a Dyson Ball is typically the release button. It is often located near the swivel mechanism of the vacuum cleaner, allowing you to release the handle or wand from the vacuum's body. This button is used when emptying the dustbin, attaching accessories, or when the vacuum is not in use for storage purposes.

The brush bar reset button on a Dyson vacuum cleaner is typically located on the cleaner head. It is often a red or yellow button that can be pressed to reset the brush bar if it gets stuck or tangled. However, the specific location of the reset button may vary depending on the Dyson model. It is best to consult the user manual or contact Dyson customer support for the exact location on your specific model.

The Dyson DC40 was discontinued in 2015.
