'''{{Wplink|Dyson (company)|Dyson Limited}}''' is a manufacturer of home appliances, most notably vacuum cleaners. The company has been involved in several incidents related to the aftermarket repair of its products.


== Battery packs lacking cell balancing, featuring self-bricking firmware ==
==Consumer impact summary==
Dyson's policies have been troublesome for [[Planned obsolescence|product longevity]] and [[Right to repair|repair]].
* Their battery design speeds up degradation.
* Adhesive on printed circuit boards makes easy repairs impossible, leading to expensive replacements.
* Restricting consumers from using third-party repair shops, forcing them into manufacturer-recommended services.


Dyson battery packs contain a Battery Management System (BMS) with a chip that would be capable of balancing the individual cells. However, the manufacturer has decided to leave away a few inexpensive but essential resistors, resulting in no balancing to take effect. As a result, the battery pack wears out much quicker than necessary.
These policies add costs of ownership and shorten product lifespan, harming consumers.[[File:Dyson-glued-button.jpg|thumb|Glued PCB, preventing repair.<ref name=":0">{{Cite web |author=@vacuumtester |title=Dyson Button Replacement is no Longer Possible |url=https://www.youtube.com/watch?v=KF0nNOAFnRQ |website=[[YouTube]] |date=16 Nov 2022 |access-date=17 Jul 2025 |url-status=live}}</ref>]]


After just a few years, spare battery packs are "out of stock" (e.g., the Dyson V8 SV10 Battery being currently unavailable in Germany), effectively suggesting that the device should be thrown away.
==Incidents<!-- Will split this into incidents and practices later on -->==
===Battery lifespan reduction===
{{Main|Dyson intentionally reduces battery lifespan and makes them difficult to repair}}
'''Dyson''' battery packs include a '''Battery Management System (BMS)''' equipped with a chip capable of balancing the individual cells. However, the manufacturer omitted a few inexpensive but essential resistors, preventing the balancing function from working as intended. As a result, the battery pack degrades much faster than it should.


Even if one charges (using a third-party charger) and balances, or even replaces the individual cells, the Battery Management System will still not allow you to charge the battery because its firmware writes 2 bytes into the configuration memory of the microcontroller that essentially bricks the battery pack. However, third-party open source firmware has been written to replace the proprietary firmware for some models, and for some models it has been found out which configuration bits need to be changed in order to un-brick the battery pack<ref>https://github.com/tinfever/FU-Dyson-BMS</ref><ref>https://github.com/davidmpye/V10_Dyson_BMS</ref>. This has been covered in the (specialist) media<ref>https://hackaday.com/2022/05/23/fighting-back-against-dodgy-dyson-batteries/</ref>.  
===Circuit boards covered in glue===
{{Main|Dyson covers circuit board in glue which prevents repairs}}
'''[[Dyson]]''' started applying a thick layer of glue to the circuit board of their devices. This makes it impossible to replace the power button for a device when it breaks, and leading to consumers having to replace the entire housing.


This anti-consumer and anti-repair pattern can be observed across multiple models and product iterations, and appears to be fully intentional.
===Removing third-party repairs options===
{{Main|Dyson ends relationship with third-party repair centers}}
The company no longer allows repairs through third-party repair centers. Dyson described this decision as ''"difficult"'' but emphasized its commitment to ensuring that ''"all services and repairs meet Dyson's high-quality standards for our owners"''.


Open source software has been written to un-brick the battery pack by overwriting the configuration bits for some models using a 3.3V Raspberry Pi board<ref>https://github.com/kumdzio/PIC16LF1847arduino-programmer/tree/main/Dyson_original_firmware_unlocker_with_eeprom_check</ref>.  
===Difficult to repair battery packs for Dyson V6 cordless vacuum===
The Dyson V6 uses replaceable battery packs that are available for purchase on their website.<ref>{{Cite web |title=Replacement Dyson V6™ vacuum battery |url=https://www.dyson.com/support/journey/tools/967810-23 |website=Dyson |date= |access-date=17 Jul 2025 |url-status=live |archive-url=https://web.archive.org/web/20250708183421/https://www.dyson.com/support/journey/tools/967810-23 |archive-date=8 Jul 2025}}</ref> The battery packs have a plastic casing that is clipped shut in such a way that opening it is impossible without damaging the casing. Additionally, the BMS used does not have a reset button. This leads to unnecessary replacements for the entire battery pack when a fault could have been resolved with a reset. For example, Steve Porter from TronicsFix was unable to repair a Dyson V6 battery pack that was stuck sending the voltage without the button pressed down because of the lack of a BMS reset button, and had to replace the whole battery.<ref>{{Cite web |author=@TronicsFix |title=Are Expensive Dyson Products Repairable? |url=https://youtu.be/Wa1dsoZK4tk?t=1109 |website=[[YouTube]] |date=28 Mar 2025 |access-date=17 Jul 2025 |url-status=live}}</ref>


== Unfixable buttons ==
===Using under-dimensioned trigger in V10/V11 cordless vacuum===
{{Main|Dyson V10/V11 trigger design}}
The trigger design of the V10/V11 cordless vacuums uses under-dimensioned material that tend to break after some years of use.


There have been reports of buttons being "unfixable" due to the use of glue<ref>https://www.youtube.com/watch?v=cUqfrIk-FhM; [[Louis Rossmann - Video Directory#2022|Dyson's repair procedures suck, unlike their vacuums#2022]]</ref>.
