Still stuck closed, does not have a release button

press release on top cover , I had someone use mine 1ce and they pressed "seal" with no bag in machine it did exactly that it stuck closed, tight too !! one touch of release button on top cover and it popped open

Sounds like the controller microchip has become disconnected. You'll need to flip the SEBO over on its side and remove the floor head - to do this, kneel on the floor and press the release button below the main front bin to unlock the floor head from the main bin area. Putting one knee on the floor head might help as the lock might be still. This pulls the floor head apart from the main bin and user handle. Once unlocked, flip the head over and undo the 4 large screws (2 at the back and 2 near the front on either side) Once the floor head has become loose, ease it off slowly and you should see the microchip board. With the bumper in front of you look to your right hand side to check that the microchip thread has not been pulled out. Check that all points are pushed in correctly 0- you should download a parts and manual diagram from SEBO UK or SEBO Germany (Sebo.de) in English. This will show you the microchip board and the microchip connectors. Once checked, reverse process, fit screws back on with the floor head cover underneath and re assemble before switching back on. Hope it helps!

there are 4 tabs, 2 on each side. use a flat head screw driver to pry the top cover away from the bottom the clips are located close to the corners of the vacuum. after you have these clips removed, press the handle release to rotate the head up a little and the top cover will come off. (be careful not to loose your height adjustment button when you take the top off) let me know if you need any further assistance

Hello,

I'm pretty sure you're asking about a Kenmore canister vacuum,

Here's what you'll need to replace a belt on a Kenmore canister vacuum:

- Phillips Head Screw Driver
- Flat Head Screw Driver

There are two different types of belts that are used on a Kenmore Canister. One of them is called a cogged belt, which has little teeth on the inside of the belt. The other is called a serpantine belt, which looks like a car belt, and has little grooves on the inside of the. You'll be able to tell which on yours takes after opening up the power nozzle.

This is the Cogged or Geared Belt with little teeth inside the belt:

This is the other Serpantine Belt that has little grooves on the inside of the belt:
Kenmore Canister Serpantine Belt for Canister Vacuums

Here's how you can replace the belt on your Kenmore Canister vacuum cleaner. First, before taking apart the power nozzle to change the belt, try pressing the overload protection system reset switch. This overload protection feature is designed to shut off the power nozzle if something gets stuck in the brushes, to prevent the belt from breaking.




Step 1. If you're power nozzle is a square shaped nozzle like the nozzle that I took a picture of above, then you'll need to first remove the headlight cover before you can access the roller brush and belt. Simply squeeze both sides of the headlight housing, and while squeezing, lift upwards with your fingers exactly where my fingers are located in this picture:



Step 2. After the headlight cover has been removed, you'll see two screws underneath of the headlight cover, directly in front of the neck of the power nozzle. You'll need to remove both of these screws. I have circled these screws in red:



Step 3. After both of these screws have been removed, turn the power head upside down, so the roller brush is facing upwards. You should see writing that points to an area to put your flat head screw driver. You'll need to put the flat head screw driver down inside of the nozzle, and pry the top blue housing from the black bottom housing. Here's where the screw driver should go on the left side:

Here's a picture of the screwdriver prying off the right side:



Step 4. Now turn the power nozzle back over on top, and remove the top housing of the nozzle. You may have to push the handle release pedal in order to take the top housing off.


Thank you very much,

Faulty switch, undu the screw with a torx driver where the handle sits and unclip the switch cover out at both sides, be careful not to break it,
where the switch is situated they may be a spring, also test the button, if no good replace

OK...so while I'm sure that hitting the power button w/ a mallet will work...I was having the same issue and felt uncomfortable hitting my very expensive Dyson w/ a mallet. 
Here is what I did to fix the problem I have a DC17...I am sure instructions will vary by model Here is what you will need: 1. flat head screw driver 2. Torx -15 screw driver.  
1. remove the dust tank  2.Pull the extension tube (handle) out (as if you were going to  vacuum a tight area.  3. there are 2 torx screws that you will have to remove 4. there are 4 retaining clips that you will use the flat head screw driver to unlatch.   5. After you remove the torx screws and release the 4 retaining clips, the front panel (that houses the power button) can be removed.  6. This will expose the actual power button itself.  Most likely it was jammed. 7. Once you think you have fixed it...test out your fix. 8.  If fixed...reassemble

Most of these you have to take off the cover on the back end where the cover retrack button is. Usually it has a catch, 2 on each side, use a screw driver, pry up near each corner to release it, then you can get to the cover over the moter and cord reel. Remove the 2 screw and put up and out.

The top cover covering the light, push in at the sides to release the tabs holding it, then there will be 2 screws, remove them, then with a screw driver, on each side you will see a slot, put the screw driver in ther and pry up to release the catches. Then you can get to the brush roll and belt.

I solved the problem, the metal (hot!) release rod gets stuck & needs a little push.
Unfasten the top by prying off the rubber gasket after removing the top. Remove the 2 small phillips screws, then remove the front that holds the nozzle, & remove those 2 phillips screws.
Carefully pry up the top with a putty knife, inside you will see the tip of a metal piston that the plastic release knob is supposed to contact. Set it on its front, & soak the piston with a light household or sewing oil, giving it a few taps with a blunt object occassionaly to loosen, heat up & test before reassembling, but remember, the piston is very hot. When you push on the piston with a screwdriver, it should release the steam, but also stop when you let go. Work with it a little & it will come back to life.

Can't swear this is the solution for the Progressive, but on the WhisperTone powermate the solution is this: Look on the bottom; it says "to service brush, turn unit over". You probably think you already have turned the unit over (it's upside down now, isn't it?). No, turn it right side up and take the cover off the light! (On the whisperTone, that means pressing in on the rightside (as it faces you) and lift up.) You will find the two screws that you need to undo. That solved our "seems to be stuck in the middle" problem. Then turn it back over and, using two flat head screwdrivers, pry at the sides where the tabs are (there were arrows on the rubber molding to show where).
