Taking off the bumper from A Sebo K1 Airbelt - Sebo K1 airbelt Bagged Canister Vacuum

Changed Category from Refrigerators to Sebo K1.

Sometimes these appliances have hidden screws, sometimes they have hidden plastic catches and need a 'spudger'. I would think the cord retraction mechanism and spring is a large component so would need a full disassembly. I haven't seen the video in the link, but if he is getting as far as replacing a motor, he is fully disassembling. The normal way to fix a binding cable retract is put extend the cable all the way and start again.

Check the brush roller at each side to see if threads are wound around it. Also, check the brush to see if there are threads wound around it. This is what generally stops the brushes from spinning. It will take sometime to unwind the threads/lint and you may need scissors and tweezers to fully remove all of them but it will be worth it!

what is the problem first, I need to know before I can help

I work with a Sebo dealer (in the UK), where we repair all makes of vacuum cleaner. It's testimony to the quality of Sebos that in several years I've only had one of this model to repair (so my memory is somewhat sketchy). However, from first principles, the finger of suspicion points to two likely causes of this problem. First, the copper wire may have broken within the flex - this commonly happens where the flex is subject to both stress and tight bending, which is the two extremities (where the flex enters the plug, and where the flex joins the rewind reel). You will need a continuity tester of some kind to check this, of course. The flex may be visibly damaged, but often there's nothing visible externally. Second possibility is that one or both of the motor's carbon brushes is worn out. You will need to get them off the motor to check. Check both - they can sometimes wear very unequally - a new one will have about 2cm of carbon exposable, whereas a worn one can have nothing left at all. As for what's economically replaceable... it depends what you can do for yourself. In the UK a new flex complete with rewind reel will set you back about £45. However, it is possible just to wire in a length of new flex provided you make sure that any connection you make is good, safe and not subject to stress from winding and unwinding. As for the carbon brushes, in the UK they are about £5 each. For a complete new motor you'll not get much change from £100.
I hope this helps. If you need me to try again just post a reply, giving any more information you can, and I'll see what I can do. Good luck!

OK, but be warned... it's not so difficult getting the thing apart, but making a neat job of reassembly has been known to drive grown men to despair. And that's because you have to remove the airbelt. But first things first:
1. remove the hose
2. remove the hose-retaining ring
3. remove the flap that covers the green filter.
4. remove the screw beneath that flap nearest to the handle (there's a deeply recessed screw on the other side, but you can ignore that)
5. remove the clip at the back of the machine where the airbelt joins (lever it off carefully with a screwdriver)
6. this is where it begins to get interesting. The airbelt is in two parts - the bulky foam strip and a thin material cover. The cover is held in grooves, top and bottom, running all the way round the machine, by two thin plastic strips around which it is wrapped and which just slip into those grooves. The first challenge is to get those strips, and the covering material, out without damaging them. Just prise one end out with a small screwdriver and work your way around the machine - it's more a matter of patience than anything else. (The second challenge is getting it back neatly!)
7. remove the ends of the foam strip far enough to reveal two plastic clips that hold top and bottom of the body together
8. prise those clips off with a screwdriver.
9. it should now be possible to lift the top cover off. It can be a bit fiddly getting it off over the neck where the hose plugs in, but it does come off.
10. the cable rewind spool is now revealed in all its glory.
11. if you've found my advice helpful so far, here's a final piece... don't try to fit a new cable to the old spool - fit a complete new spool.
12. good luck!
I value feedback, so please remember to rate this response.

Fasco has been out of business for several years. The motors are still available. You will need to find the model number off your old unit. Once you have that model number you can find the replacement motor at one of these websites.

This is a dead motor. the electrical motor is experiencing windings failure and will have to be replaced or rebuilt. Just to be safe, remove the switch and test with voltage needle to see if the problems here. i suspect total motor failure.

Remove the belt or seal that goes around it, there are some clips to take out, then it will separate.

No screws under the castors. There is 3 case clips, the bumper hides them, maybe this picture will help:
