The blown part is a ceramic capacitor probably doing some electrical smoothing of some sort.

Those ceramic capacitors fail all by themselves from time to time. I'm not surprised the motor still works without it. I've just repaired our DC62's motor which had died. One of the switching transistors had failed. They're on the back side of the board, so you have to desolder the big connections to the tags of the motor windings then withdraw the PCB. The transistors are surface-mounted. With the right tools, they're not hard to test and replace.

Hahaha, you really deserve a BIG like my friend. thank you for the video.

My V10 blew up when I changed gears with the trigger engaged. I went from medium speed to top speed, and it burned. Dyson will replace it, but I am worried once the warranty expires, Dyson won,t fix it. It seems like a simple problem; I am surprised Dyson hasn’t addressed it. Good thing, you can fix it. But still. It is an expensive vacuum, and I don’t know any decent electrician in my area.

Also, what are those little disc air fresheners that you use?

Hi, is the SA1 the negative side of the terminal? I can’t figure out which side is the positive side.

Hi! I have an v10 that looks like it wants to start but stops makes a sound like it would have a loose connection before it stops. This happens every time i press the power and then wait for 10-20 sec

Since you have completely disassembled the engine, can you also tell me what the capacity of fuse C6 is? mean it burned through.

You mentioned which one is newer. Isn’t that the date on the top right of the board? The one that blew is 01/07 and the good one is 01/09?

Please help. Do you know how to change over a motor on a V8??

Hi. Will be so kind if you help me. I have got V10 and external brushes not work at all. I've checked mosfet q16 and it seems ok. Any ideas? Thanks.

I had a V11 that was water damaged and the driver board was burnt it's not very good when there is plastic all around the digital motor could cause a fire when your using it unless the plastic dyson use doesn't combust

What is your vacuum servicing business called, I can’t find it?

Hi thank you for your interesting video! Could you help me? I got a used Dyson V11 Absolute without battery. I connected the + and - inside the handle and the lcd behind the filter lights up a little bit but the dyson doesn't work...I noticed there are two more circular pins inside the handle but i don't know what they are (additional power, button, etc) i even tried to find a diagram but i didn't got anything, do you know what they are or can you tell me where i have to connect them? I saw a video where maybe they go to the motor control board but i don't know what they are... I'm really desperate and i don't want to spend extra money for a new battery...thank you very much!

Is there a trick to removing the motor from its plastic case?

maybe the failed cap. is part of the charging circuitry?

C6 will be a capacitor did you try it near to an AM radio?

If I designed a new vacuum it would be a corded upright vacuum featuring a 600 watt high efficient brushless suction motor with over 120cfm and 100 inches of water lift and emits a nice soft 525 hertz tone on the max power setting and is almost as tiny as a shark 750w screamer motor but with a larger fan to motor ratio. Takes non woven cloth bags, disposable pre motor filter, and a replaceable HEPA filter. Also for a fee you can get the carpet model which comes with a wessel werk EBK 360 for grit busting agitation. The base model just comes with the bare floors straight suction head.

0.1uF 50V 0805 chip cap. Bypass only, not too critical.

Wait a second, dyson won't even repair a machine for pay anymore? When my v10 goes bang a month outside of warranty I guess I'll be up a creek. That's really sad, I wish vacuums weren't becoming non-repairable, expensive, and not long lasting like smartphones with yearly upgraded releases. Dyson are even trying to phase out their independent service centers in the USA.
