In reply to Autovacs post, thought I would do a new thread so it doesnt get lost in the bulk hose one.
This is how I repair 07 hoses. Out of a box of 27ish from mvacs, and another box of 30 I bougth from dysondealscornwall on ebay, I reckon a good 20 of them were easily fixed, with the other 7 yeilding their ends for spares, as this method does sometimes break them if their brittle, as you will see! DC04's are slightly different, but I cant find one to do atm so will have to do that when I get one in, the internals are different.
Have probably put 10odd on machines and sold them, and not had one back. Had one DC07 back with a torn hose, but I hadn't fixed that at the time as it was good, she got it out of her car, started asking how long it would take etc and I changed it there and then on the road for another one, she was pleased!
Anyway, this is my method. Never tried anything newer than an 07, so can't help with 14s onwards as their different by the looks of things
(ignore the hose cuff, just grabbed the first end I found, as when the hoses arrive I go through and chop the ends off to keep the hoses tidy, then just match them back together afterwards. Need to get the brake cleaner out and remove the tape residue before using it)
Tidy up the end of the hoe, snip any excess coil back to a good part of the palstic, and trim the plastic back
Then, pull the crap out of the cuff end with some pliers. I find this essential as removing the wire releases the grip of the parts, as it doesnt pack them out anymore
I then get a good flatblade screwdriver, and on the opposite side to the suction release valve, place it over the inner black hose holder, there's a gap just big enough
One well aimed smack with the hammer jumps the locating peg out of its slot. It's at this point the job becomes do or die, brittle ends split down the middle. That's why I always chop them off of scrap hoses (where the splits been pulled and buggard up a good quarter, or it'll never wash clean again sort of thing)
Now one sides off, it should be loose enough to deliver a lighter tap to the other side, then pull the black part out of the housing.
and split. Be sure to catch the two springs too
Now you clean up the black part, a combination of pulling, small flatblade to prise it off and a sharp knife does it
The hose twists onto the black part by a coil and a half, you may need to adjust the plastic on the first coil so it doesnt fold under itself
I give everything a wipe down at this point cos it's easier than piddling about when back together
Time for glue
I found this at halfords when desperate and couldnt wait for ebay. Only really use it for this job, and gluing the tab back onto DC04 switches... £2.something on ebay, £7.90 at hallfrauds
Small bead around the bit where the hose twists on
The first half a coil pushes on, then start twisting. You should see the glue start to spread underneath
Once done, you need to put the release valve back in. The springs are an arse, they pinged out twice just doing these pictures!
Then line the locking tabs up with the holes, and push home until it clicks! Check the release valve pushes in too
Little test stretch
and job's a goodun. The outer housing clamps the hose to the innder on an 07, which helps alot
I then put it with the rest of my clean ones from boxes of scrap under our bed...
Which all washed up ok
Need to find the box of random ends and get the 8 washed but end-less hoses finished that are in the wardrobe, they've been there too long!
Hope this helps! Now when I get a machine in, I just put a clean hose on and put the one from the machine into the to wash/to fix pile for another day! Only have one 04 hose left though, might be more in the shed though, couldn't find any when I looked to get the end for this one out!
Next time I have an 04 hose to do, I'll post it up. I think 03 hoses are the same as 04 ones too.
