Burnt smell from DC04 after new motor change
« on: May 10, 2014, 11:42:36 PM »
I recently and successfully change my burnt out motor (and HEPA filter) on my DC04 Absolute and I am very happy that the vac is working again and even better the suction is much better than it was  :thumbsup:.

However, when I use the vac there is still a strong smell of burnt motor coming from it. I removed the HEPA post motor filter and tried to clean off the black stains (carbon?) in the motor housing as much as I can. But not much of it comes off easily. How do I get rid of the smell and is there an easy way to remove the stains? Is it just a case of dismantling again and washing all the effected plastic parts in soapy water?

Thanks in advance.

You need to change the HEPA filter. The smell wont go away until you do.

Also, that it will be blocked with carbon will reduce efficiency and put stress on the new motor - shortening its life.

Edit: Sorry, I read that wrong maybe. You replaced the HEPA filter or cleaned it?

I'd go with componentise everything a f wash it in hot soapy water with a little brush.

The carbon dust will have gone everywhere! Strip the cyclone and wash that too to bring the performance back.

Just don't take the release valve out of the cyclone as I find they always break the cyclone housing slightly. Bung everything in the airing cupboard and let the hot water cylinder bake everything dry.

Shout if you have any issues, I and others know what goes where when blindfolded!

Then new filters. Even the washable motor one. Under 10 easily and piece of mind.

Then voila! Brand new dyson!

the airing cupboard

There is a phrase I haven't heard in years! Do people still have those?  :underchair:

Ours is great! Hides all the bedclothes and provised me with a drying chamber!

Sprung a leak from a join earlier though, so ours has a tupperware catching an occasional drip whilst we inform the landlady!

I have already changed the HEPA filter to a new one and washed the blue sponge that sits on top of the bin assembly. I also dismantled and washed most of the vac except for the bin assembly and cyclone.

The carbon dust deposit was stubborn to wash off but with plenty of elbow grease and CIF, most of it came off. However I am a bit concerned about the motor housing. This has the most dust and the plastic is actually stained and cannot be washed off. I also noticed a few small specks of copper embedded in the plastic. So it must have got pretty hot in there before the motor blew out. I was wondering if it's worth replacing the motor housing? Also I would like to wash the bin and cyclone as suggested but not sure how to disassemble it. Are there links on how to do this please?

Thanks.

I dont have any pictures tbh, Mvacs might but the process is:

Remove cyclone
Remove bin
Open top filter lid
remove the washable filter
undo 2 torx screws
pull the cyclone out of the housing (note which way round it goes at this point, I'm sure it only goes back one way but something lines up to make it easier...)
Holding the resulting bit of cyclone by the shroud, give it a massive wollop on the pointy bottom of the cyclone on some carpet and the two should seperate (the shroud clips into a groove on the cone)
Remove the rubber seal from the cyclone cone but dont bother about the one around the edge of the cyclone housing, it's a pain to get back in!
Pop the outer cone out of the bin and remove its seal too
Small flatblade screwdriver to scrape the worse of the crap off, then wash with hot water (dishwasher, shower, sink etc)
Leave in hot place (airing cupboard etc) for a day, preferably so it catches the hot water a few times.
Dont bother trying to get the release valve out unless you feel brave, I always end up cracking the cyclone housing slightly. Bit of glue normally sorts it. Just blast it out with water as best you can

Re-assemble and voila, more suction I expect! Of course you could then strip the rest back down and wash:
Brushroll (pop the bearings out with the very end of the metal bar that runs through them)
brushroll end caps
brushroll housing
sole plate
internal hose
clutch cover (remove the metal bar)
motor housing
suction divert valve (squeeze the black palstic ring and it will pop off the clips
wand blockage valve
chassis
wand

etc! Good luck!
