# Dyson Troubleshooting and Support > This site contains support and troubleshooting content for all Dyson products in the form of step-by-step guides and question-and-answer diagnostics. ## About Dyson Support Dyson's online support offers authoritative help for Dyson vacuum cleaners, air purifiers, fans, heaters, humidifiers, hair care devices, and wearable technology. Visitors can access both quick answers to frequently asked questions and detailed troubleshooting instructions designed to resolve common and uncommon product issues. Technical manuals, filter change guides, cleaning advice, and best-practice maintenance updates are available for every category. ## Common queries - Cordless floorcare: The most common issue experienced by users of Dyson's cord-free vacuums is a pulsating or "cutting out". This is not a problem with the battery or trigger, and is in fact the motor turning off due to lack of airflow. To address this, check for blockages and clean the filter as outlined in the [Cordless support](https://www.dyson.com/support/vacuum-cleaners/cordless) section of the Dyson website. - Corded, plug-in floorcare: If you feel the performance of your full size plug-in vacuum isn't what it should be, the most likely cause is a dirty filter. Dyson vacuums have a filter that needs to be washed regularly; information on how to do this can be found in the support section for both [Cylinders](https://www.dyson.com/support/vacuum-cleaners/cylinders) and [Upright](https://www.dyson.com/support/vacuum-cleaners/uprights) vacuums. - Haircare: Dyson's hair care products are designed to turn off before they overheat, if your hair dryer or styler switches off, check that the filter around the intake is clear. Information on where to find the intake and how to clean it can be found in the [Hair dryer](https://www.dyson.com/support/hair-care/hair-dryers) and [Hair styler](https://www.dyson.com/support/hair-care/hair-stylers) support sections of the Dyson website. - Purifiers: To get the best performance from your Dyson purifier, make sure to replace the filter whenever the machine prompts you to do so. You can find out how often this needs to be done and how to swap the filters in the [Purifier support](https://www.dyson.com/support/air-treatment/purifiers) section of the website. - App & connectivity: Help is available for connecting the MyDyson app and using smart features for [headphones](https://www.dyson.com/support/headphones), vacuums, hair care and environmental control machines (select your product from the [Dyson Support Homepage](https://www.dyson.com/support) to get started. ## Features of Dyson Support - Self-service troubleshooting for error codes, performance drops, and maintenance. - Videos and visual guides for installing replacement parts, cleaning filters, and resetting machines. - Online chat, telephone support, and email options for direct expert assistance. - Warranty claim and registration information for fast resolution. ## Product-specific support ### Floorcare - [Cordless](https://www.dyson.com/support/vacuum-cleaners/cordless), including Dyson V8 Cyclone, Dyson Gen5detect™, Dyson V7™ stick and Dyson V8™ stick - [Handheld](https://www.dyson.com/support/vacuum-cleaners/handhelds), including Dyson V7™ handheld, Dyson Car+Boat and Dyson V6™ handheld - [Wet and dry](https://www.dyson.com/support/vacuum-cleaners/wet-dry), including Dyson V15 Detect Submarine and Dyson V9 Submarine - [Wet floor cleaners](https://www.dyson.com/support/floor-cleaners), including Dyson WashG1™ vacuums - [Multi-directional](https://www.dyson.com/support/vacuum-cleaners/multi-directional/omni-glide), including Dyson Omni-glide™ - [Robots](https://www.dyson.com/support/vacuum-cleaners/robots), including Dyson 360 Vis Nav™ - [Cylinders](https://www.dyson.com/support/vacuum-cleaners/cylinders), including Dyson Big Ball, DC54 and DC47 - [Uprights](https://www.dyson.com/support/vacuum-cleaners/uprights), including UP34, Dyson Light Ball and DC50 ### Hair care - [Dyson Supersonic™ hair dryer](https://www.dyson.com/support/hair-care/hair-dryers) - [Dyson Airwrap™ styler](https://www.dyson.com/support/hair-care/hair-stylers) - [Dyson Corrale™ and Airstrait™ straighteners](https://www.dyson.com/support/hair-care/hair-straighteners) - [Dyson styling products](https://www.dyson.com/hair-care/styling-products/chitosan/frequently-asked-questions) ### Environmental control - [Purifiers](https://www.dyson.com/support/air-treatment/purifiers), including Dyson Purifier Cool, Dyson Purifier Hot+Cool Formaldehyde and Dyson Pure Cool Me™ - [Humidifiers](https://www.dyson.com/support/air-treatment/purifier-humidifiers) - [Fans](https://www.dyson.com/support/air-treatment/fans), including Dyson Cool™ tower, pedestal and desk fans - [Heaters](https://www.dyson.com/support/air-treatment/fan-heaters), including AM09, AM05 and AM09 ### Headphones - [Dyson OnTrac™](https://www.dyson.com/support/headphones/ontrac) - [Dyson Zone™](https://www.dyson.com/support/headphones/zone) ## Search keywords support, troubleshooting, Dyson, vacuum cleaner, cordless, cord-free, floorcare, upright, cylinder, stick vacuum, wet and dry vacuum, filter cleaning, hairdryer, Airwrap, Supersonic, Corrale, Airstrait, purifier, humidifier, fan, heater, wearable, headphones, robot vacuum, connectivity, MyDyson app, maintenance, error codes, warranty, replacement parts, repairs, technical help ## Accessibility The Dyson support site is accessible on mobile and desktop, offering clear navigation and practical advice for users worldwide.
