This is a little joke that Hoover has played, and for some reason no one else has explained it. (One answer hints at it, but doesn't explain at all.) The height adjuster does NOT operate when the vacuum is in the upright & locked position. The tabs for the adjuster won't go into the holes above them until the vacuum is unlocked and at a slight angle. You can just install the height adjuster wheel assembly in the locked position, replace the lower cover, and voila! you will be able to adjust the height with the vacuum angled as it is for use. That's an hour of my life I won't get back!

Hi There Alec from VacuumSpot here.
Most of these machines don't actually change the height until the handle is lowered so even though you change the dial when it is an upright position it is not until you lower the handle that the height is actually selected. Assuming that you are aware of this and it is still not adjusting I would suspect you have a small arm or lever broken. It is very rare for a height selector to simply fall out of place.The job would take 5 minutes in my opinion so it is simple but a bit fiddly.

No site available for that, but the height adjustment on this machine only works when you let the handle down.

In my experience, Hoover height adjustment are "stops" rather than being attached to an axel. Look for something that rould resemble a set of circular steps somewhere in the path the axel would take as it goes up and down. It is usually on the underside from the knob that sets the height. Each 'step' represents a height with the shortest step being the lowest setting from a certain perspective.

On some Hoovers, therte is a ratchet petal on the right side. The ones I have seen are similar in operation to the above.

Let me know if this helps you.

move the height adjustment up a little

One compatible belt that I use and works (at least while its new) is Royal 104425001. Try that.

this usually means your belt is worn.

your floor adjustment spring is broken there is a plastic slider and clip if it is broken the height adj will not work you should get a new vacuum because this repair can cost as much as a new vac.also this is a common problem with the hoover brand I would get a sebo or an oreck they have a great warrentty and you will more than likly never buy a other vac.

Sounds like you have a bad brush roll(48414115), take it out and see the the ends turn freely or not, if not, then replace it. Also check the the slots that the brush roll sits in to make sure they haven't melted. I am assuming that the motor is running, if not, then it may have froze up.
