Bissell 3920 height adjustment not working

The adjustment knob and the wheel plate are not even touching. Tried looking for "spring" as mentioned in previous blogs, but no spring is there. Does anyone have a schematic of this vacuum?

SOURCE: Carpet Height Adjusment

In addition to the tab that contacts the bottom of the slider, there are 2 protusions on the adjustable wheel plate that move through holes in the housing, but only when the handle is tilted to begin vacuuming. The wheel plate has a spring that forces the tab against the slider. As the handle is moved to the upright position, the protusions move back through the holes, taking the tab away from the slider and the wheel plate locks in its highest position. Therefore, the position of the slider has no effect while the handle is upright and locked. Hope this helps.

SOURCE: height adjustment not adjusting

The height adjustment wont engage unless the handle is in the down position. Not knowing this led me to overturn the hight adjustment knob.

Step on the handle release, pull the handle back and lay the vac on its side. Then you can get the knob and the plate back together again.

BTW, the reason I had this problem is because the front brush slows dramatically when using on carpet, I thought it was set too low, and turned the knob (in a manly fashion, putting it past its limit). Still working on that one. After inspecting the belt, looks like one worn and cracked spot gumming up the works.

It is because the belt is worn or stretched and needs to be replaced. Here are the belts you need and the manual which has instructions:

Still dont know hot to get height adjuster knob to work. tried handle all the way back n lay on side solution that was offered. the plate has a permanent place to sit. hows it possible to bring knob


Hey, not having a working height adjustment can be a bear. Lock the vacuum in the upright position, change the knob to desired setting, and recline the handle for adjustment to occur.

If you are still having difficulty, you may want to have your vacuum inspected by a Qualified Technician at one of our Authorized Service Centers. Here's a quick link to assist you in locating one.

My front wheels fell off how do I fix it. there is a slender long spring and I don't know where it goes


That spring connects to a slot beside the height adjuster knob and a hole in the base to the wheels that fell off.The problem is you can't get the wheels to go back in flush so the height adjustment works.The vacuum will not be close enough to the floor to get any type up suction or brush contact.To change that spring as well as the belt,remove the cover by taking out two screws,one on each side.Force the rller out by prying the right end out of the slot.

Brush will not spin any longer


If the brush won't spin at all, it's either the drive belt or the roller beater brush is clogged. Pet hair can quickly clog a vacuum. Turn the unit over and see if the brush will rotate by hand. If yes, it's probably the belt. Also look for debris and clear as much out as possible. You may have to remove the bottom plate and clean the bottom of the unit out. If you do have to go that far, it would be best to replace the drive belt and thoroughly clean the vacuum.

Spring connecting height adjustment


There should be a place easily for the wheel assy to fit back in and then if you look you should see 2 small holes in the bottom of the vacuum that it will slip into. If your looking at the vacuum straight they should be on the left side on the bottom.

I can see the height adjuster under my Bissell pet hair eraser vacuum, but it doesn't adjust. The parts don't look like they're touching. It's been iffy since I took it out of the box. Now it doesn't...


http://uk.bissell.com/images/UserGuides/3920E_508.pdf

This is the pdf manual. If you look at page 12 you'll see that the bottom of the machine has been pictured. Between the middle wheels near the brush (where arrows 4 and 2 are) you'll find that the adjuster bar has a sprung mechanism. Now this is easy if you have time! If you take off the or just inspect the bar, check to see that nothing is clogged behind it. If it looks fine, check with your other hand by moving the rotary dial a couple of times and your other hand pressed down on the central bar between the wheels - if you can feel that the bar is moving whilst you turn the rotary dial then it should be working. Sometimes the spring that connects the dial to the bar can loosen and this may well have been the case. If you can unscrew the assembly do it gently as it will pop up to see if the spring has been put in place and then carefully put everything back together.

Some uprights don't allow the height adjuster to adjust whilst in the upright position though but if it doesn't adjust at all then the spring has definately moved.

Height adjustment


You'll have to turn the upright to its side to show the sole plate where the rolling brush is. Check where the front wheels are located and ensure there is no blockage obstructing the rotary dial. Sometimes the spring mechanisms can work themselves loose. 
Inevitably you'll have to remove the sole plate and/or the rotary dial which may be screwed down. If it has cracked then you may have to seek a replacement. 
Dont forget to rate this suggestion.
