heck for a release button or lever at the base.

Hi! Below are step-by-step instructions for trouble-shooting your Hoover U6476.

1. Locate the primary filter behind the side grille. Wash the filter, squeeze it out and allow 24 hours to air dry outside of the vacuum. It should be washed about every other month.

2. Locate the secondary filter located in the vacuum base under the paper bag. The secondary filter can be washed in the same manner as the primary filter.

3. Replace the bag if it is full.
4. Remove the hose from both ends. Use a broom stick to gently loosen and clear any clogs from hose.
5. Remove the bottom plate and brush-roll. Use a wooden spoon or something similar to loosen and remove any clogs from the lower hose.

6. Check that the brushes are still spinning. If not, replace the belt.
Hope this helps!

No, once the belt is stretched and worn there is nothing you can do, you have to replace them. Here is the belts you need for your model:

Hoover U6476-900 Belts

Inspection of the circuit board found that the 470uF capacitor looked damaged. I replaced it and I now have the Green and Red lights are working correctly.

yes it is the right belt. the easiest way to get that belt on is to put it on the motor shaft first, stretch and start at the top of the self propelled pulley and rotate til the belt tracks on. you will need to keep pressure on the belt while you rotate the pulley. make sure you install the 38528-034 first before the flat belt

here is a similar model

take it in for diagnosis - seems to be an offset perpenducular drive axis.. seems to me.

move the height adjustment up a little

If the rod isn't pushing the switch, then something inside the handle asm. broke and isn't holding the rod in place. More often then not, it is the switch, but could be the rod in this case.
