DC41 - Pop,Bang, Smell, Help!
« on: February 15, 2018, 12:18:02 PM »
Hi All,

New member and first time poster here.

Have had a quick search for my issue using the search filter, but no joy - so hoping for a few ideas if at all possible..

Whilst using our DC41 it literally went pop, the brush-head stopped working and a slight smell of electrical component failure followed.

After a quick Google I found this site and assumed that the brush-head motor had failed, as the unit was "sucking" OK.

Decided to order the complete brush-head unit from Manchester Vacs, which duly arrived a few days later.

Swapped over the brush-roller etc and fitted to our Dyson, but unfortunately the problem remains - dead brushbar.

I've spoken with MV and they kind lady suggested it may be a loom issue but to post the issue on this Forum, hence the post  ;)

I dont have access to  a Multimeter, so am unable to check if I have power/continuity to the head, so am really after suggestions as to what the most likely cause is?

I must admit, our DC41 is a bit like Triggers broom - I've replaced various parts in the few years we've had it, and after forking out for a new brush-head assembly I'm now torn between chasing my tail and throwing more money at it or just biting the bullet and buying a new vacuum, which will most probably not be a Dyson..!

Any help/ suggestions greatly appreciated.

We are in Hertfordshire by the way, in case there are any decent local specialist repair shops local to here that I haven't found yet..!

Thanks,

JC

I'm sure Tayyab on these pages has had PCB issues before, I'll give him a nudge. I'm not too familiar on 41's to be much help, but if the main motor works, and you have a brand new cleanerhead it points to the PCB being at fault!

Thanks Beko,

Have had a look at the DC40 strip down thread and it looks a bit of faf to get to the PCB for a first timer, but I consider myself fairly competent - and on the basis its not working now anyway, may be worth a punt if not an expensive part.

I was wondering if it was the loom wiring as suggested by the shop, but its not really that old, annoyingly 3 weeks past its 5 year guarantee date!

It's not the easiest, it took me about 20 minutes to figure it out when I put the photo's together for that thread! In my experience of the older DC25 which has it's fair share of yolk loom issues it just stops the brushroll turning when the wire breaks, no electrical smell. There could be a chance both wires are chafed and have shorted, but that would be unlucky...

Ah, OK thanks.

Mine really did go Pop, so something has def shorted or blown, but I guess that could be a component on the PCB or a wiring short..

Whatever I decide I need to do it quickly as I'm fast getting grief from SWSBO as shes having to use the hand attachement to hoover the carpets  :grinn:

You have gone as far as you can feasibly go without a multimeter really.

The loom issue is more known with the DC40 but possibly the 41 too, but with the symptoms you describe, I'd be thinking the previously faulty head has also taken out the PCB in the machine.

You need to test the DCv output from the machine, no other way to go really. PCB most likely but loom and/or switches cannot be ruled out too.

Buy her a Sebo instead. >>This<< is jolly good value with a 5 year warranty. A warranty you are unlikely to need.

Never had a 41 pcb go wrong, had a dc40 one with a blown picb though
The main motor worked but the brush motor didn't work despite the head being fine

It's a simple pcb only 4 wires connect to it
DC14s are tanks, just need a slightly longer motor life. Do plastic parts often break on DC14s? Nope. DC41- Sexy looking futuristic and powerful machine. Just needs a better designed cleaner head wheel and cyclone clip along with a dense metal rod in the chassis.

Thanks for the info guys.

PCB ordered, so will have a go at replacing when it arrives.

If that works happy days, if not I will admit defeat and suspect the Sebo or perhaps a Shark will be the next vacuum for us..

You'll see the loom when you get access to the PCB so it's going to be either one or the two

Well I finally got around to taking the machine apart to replace the PCB..

On opening her up it and removing the covers it became clear that the loom had worn where it passes under the bottom of the machine (design flaw..) and the wires had shorted.

This in turn had popped a resistor/track on the PCB.

Took a photo to ensure all wires went back as I found them, replaced the PCB and then cut back, re-fed re-soldered and heat shrinked the offending cables and put the machine back together.

Happy Man - All now working again and a nice clean new motor head to boot, so its looking (almost) like new again).

#smallwins - must admit to feeling a sense of relief and slight smugness to the fact that the damn thing didn't beat me (for now at least..!) :thumbsup:

Thanks to everyone's help. These tyoe of Forums are a great source of information and assistance, and its good to know that with a modicum of ability and tenacity  :reading: you can save yourself some money, that you can then rightly justify to spend of something far more frivolous..!

Bloody hell we are good here. Psychic diagnosis by phone!  :icon_nod:

Glad you are fixed up, JC.

Well done! You'll be having the cyclone apart for a good wash next...
