Shark VR750 brush error fix
This is what was wrong with my Shark.
It would run for about one minute then shut down and flash a code for “brush roll is jammed” (spot and dock both flash).
I first thought it was just the hair that had worked it’s way into the hole around the drive shaft the moves the brush.
What I did was take the thing apart, it not hard to do if you have the right tools. What you will need is a standard Phillips head screwdriver, and longer flat head screwdriver, a number T5 and T15 Torx head screwdriver. (You may not need to take the Shark apart to do the fix that I did. It might be possible to just pry the little yellow plastic drive cog off with the flathead screwdriver and pull the hair off.)
Started by loosening the two screws the hold the battery cover in place and removing the battery on the bottom side of the Shark,Then us wing the T15 removing the 9 T15 screws on the bottom side of the Shark.
Then use the T5 to remove the 7 small screws that hold the plastic trim to the front bumper on the Shark,
Then you can open up the Shark from the top by removing the top cover.
Using the Phillips screwdriver remove the silver screw that hold the brush drive motor in place, and disconnect the wire from the circuit board. After that the motor can be removed.
Then use the flathead screwdriver to slowly pry the yellow drive cog off the black housing. At this time getting all the hair off was easy! But that still wasn’t the issue. I noticed that the shaft didn’t spin. It was stuck in place so I removed the 4 silver screws on the backside of the black plastic motor housing. Using the flathead screwdriver I slowly pried the black wheel off the shaft on the inside. Then I say what what the real issues as. The barring was RUSTED! I sprayed a little WD40 on the baring and let it sit for a few minutes and took pair of pliers to grab on the shaft and while holding the housing started to try and move the shaft. It was stiff at first but after a little working at it, it started to move freely. I used a paper towel to remove the brown WD40 and repeated that step a few times until the WD40 stopped getting brown. I squirted a small amount of WD40 on one more time.
Put it back together and the Shark has worked fine ever since.
