Green light The green light was working but not now, the brushes still spin. I checked the roller and the latches are in the right position. Not sure what this means.

Check that the drive shafts and bearings aren't rusted or frozen with junk. Try spraying them with WD40 and gently manipulating them in an attempt to free them up. It may require you manually disassembling some of the casing to get to the drive motor...

Lubricate each end of the roller brush with motor oil. Bearings inside the roller brush need lubrication for the brush to turn easily. Remove any pieces of thread that have wrapped around the roller brush. If it does not spin after doing the above steps, then either the belt is slipping or the bearings are severely damaged in the roller brush. Then you need either a smaller belt or a new roller brush.

If you mean the light on the top or side of the Power Nozzle, yes, it should be on for most uses. You can disengage the belt for other uses. The green light illuminates when the belt is turning the brush roll. So, you see, the green light functions to confirm to you that the brush roll is spinning. For carpet, you would want the brush roll spinning. When I vacuum my comforter or sofa, I don't have the belt engaged because I don't want the roller to grab up my fabric. For that use, the green light is not illuminated.

If this is happening right after you turn the vacuum on, you probably have a belt issue or a brush roller issue. I would start with checking your brush roller to see if it spins freely. If it spins real freely, your belt is probably broken. If it spins freely but with some resistance, you still might need to replace the belt. I just worked on one last week that had that problem and a new belt fixed it. Worse case scenario, you might have a bad sensor. That sensor looks for the brush to spin at a certain speed and if it does not sense the right speed, it shuts the vacuum down and the light flashes. Hope this helps!

Atthe bottom of the vacuuam are screws to take off...two of them are near the rear wheel assembly....two of them are behind the front mini wheels (just pry the front mini wheels so that they pop out...they pop back in)
Remove all of the screws. Remove the bottom from the top..they come apart in two pieces. Ceck the belt on the bottom piece. Slide the roller out starting from the end opposite from the motor end. With the roller off, slacken the the belt so that it misses the gear on the motor (you will have to hold it with your hand). Plug in the vacuum. Turn the power on to the roller on position. The motor should work and the green light should be on. If the motor doesn't work, then it is defective. If it does work, turn off, unplug and shoot the gear and the two ends of the roller with WD-40. reassemble. good luck.

There's a Capt. Obvious fix to check before you go any farther. Like many vacuum cleaners, the brushes on the Bissell carpet cleaners, by design, only spin when the handle is not locked in the upright position, so be sure to plug it in, turn it on, and depress the foot pedal to lower the handle while watching the brushes one more time to be sure that the fix isn't that easy.

If the brushes still won't spin with the handle in the unlocked position, lift the handle back up into the locked position, power off and unplug the Bissell, and look down and see if either of the two belts that make the brushes spin are broken, as a broken belt, or a belt that's come off the track, is the next most likely problem. Both belts must be unbroken and in the right place for the roller brushes to spin.

These belts can be seen in the clear plastic pieces on either end of the roller brushes. If you're having trouble locating them, **with the Bissell unplugged so the brushes won't suddenly start spinning and hurt your hand**, try spinning the brushes with your fingers while watching for the belts. They're black, about the thickness of two quarters, and the bigger one of the two (on the left end of the roller brushes, as you face the front of the Bissell), is just big enough to fit around both roller brushes. The smaller belt, goes around the back roller brush on the right and to a smaller cog wheel behind it. If you see a broken belt, or a belt off the track, that's your problem.

Here's a video you can watch for free on Bissell's website that tells how to replace a belt. I'm sure the belts can be ordered online somewhere or found at some Bissell dealers or repair shops. Note, again, the two belts are different. If only one is broken, be sure to order the correct one.

If the belts are intact and in the right place, does the metal cog wheel behind the roller brush right turn when the Bissell is on and the handle is dropped? If not, then the motor that turns that cog wheel must be burned out.

Yeah, it’s annoying that the manual doesn’t give more detailed instructions and drawings to help with this, because you do have to take the roller assembly apart sometimes to clean built-up carpet lint off the unit properly. If you don’t do this, I’d expect you’d have more problems.

I have a different model number Bissell Proheat than yours. Yours may have different parts or go together differently than mine, but I'll tell you how I do it on mine and you can try my way out and see if it helps you.

(In all cases where I use left vs. right or front vs. back, as when these terms are used with a car, I am facing the front of the Bissell. I am NOT behind the Bissell, where I would stand when cleaning carpet with it.)


Here's how I put it together. This takes much longer to describe than to do, once you figure out where everything goes and you get the hang of doing it!

Attach the left arm with the two silver rods (ONLY attach the left arm here-- leave the corresponding right arm, which looks like the left arm except it has no silver rods, off the bottom unit of the Bissell, for now) to the left side of the Bissell, with a silver screw with a built-in washer. The screw hole is on the back end of the arm and the arm dips down towards the front of the Bissell and holds the two brushes in position so that they can turn without striking the top of the underside of the Bissell or dragging on the floor.

Put a small silver washer on each long, silver metal post, where the roller brushes will go, and slide it all the way to the left.

Put the larger rubber belt around both metal posts, about halfway to two-thirds of the way down the metal posts.

Slide the brushes halfway down the metal posts and attach the larger rubber belt to the cog wheel on the left side of each roller brush. Then slide both roller brushes with the large rubber belt attached all the way to the left so that the cog wheels are against the inside of the left arm. As you move the roller brushes almost all the way to the left, you may be blocked from reaching the end until you carefully work the rubber belt around a plastic flange on the inside of the left arm, but do this and be sure the roller brushes are up against the inside of the left arm. Make sure the rubber belt is still on each of the cog wheels when the roller brushes are pushed all the way left. If you turn one roller brush, the other should turn, too, because of the belt attached to both cog wheels.

Put the small belt around the small cog wheel on the bottom unit of the Bissell behind the right end of the back roller brush, and also around the cog wheel on the right end of the back roller brush. (The right cog wheel on the front roller brush is the only one of five cog wheels without a belt, when everything is assembled correctly.)

Put a small silver washer on the right end of the silver rod passing through the back roller brush.

NOW attach the right arm, using a silver screw with a washer, to the middle screw hole on the right side of the bottom unit of the Bissell. The right arm should mirror the left arm, so that the two arms hold both roller brushes in position on the right side and straight across the bottom unit of the Bissell. It is normal for the roller brushes and arms to be able to flex up and down a bit, when everything is put together correctly. The built-in washers on the silver screws which attach the arms keep the arms and roller brushes in the generally correct position but allow them to flex.

Now using your fingers you should be able to slowly spin the roller brushes without the brushes contacting the top of the bottom unit of the Bissell and without dragging too low against the floor. Check one more time and be sure the belts are positioned correctly around four of the five cog wheels.

If everything seems right, attach the two side covers. These are not interchangeable; the left cover only fits on the left. The short black screw goes in the back screw hole, and the long black screw goes in front.

Then attach the front cover. It's important to be careful that the hooks on the front cover are inside the side cover holes designed to hold the hooks before trying to tighten the last screw through the tab on top of the front cover. If you aren't careful about this, it's easy for the front cover to be out of position or to break its tab.

Try powering up the Bissell and see if the rollers spin correctly. Remember that the handle must not be locked upright and the trigger must be depressed with the Bissell turned on before the roller brushes will spin. (Sometimes people complain that nothing happens with the unit turned on and the trigger depressed when the only problem is that the handle is in the locked upright position.)

Good luck!

You need a new belt. When the green light goes out, that means your brushroll has stopped spinning. Here's how to change it....

Even if you just replaced the belt, this guide will help you make sure that you got the brushroll back in the right way.

Hope it helps....

I don't know how old your machine is, but the belt should be changed at least once a year and you should check to make sure the roller spins freely. There are bearings at either end of the roller and they will become contaminated with dirt and hair after a while and will need to be serviced. A new belt will help, but won't last if the roller is in need of service.
