Shark Rotator NV502 Troubleshooting

Vacuum won’t turn on ¶ 

The vacuum won’t power on

Not plugged in correctly ¶ 

Make sure the vacuum plug has a secure connection to the outlet or it will not turn on. A way to check this is by gently wiggling the cord to make sure the plug does not fall out of the outlet.

Circuit Breaker is tripped ¶ 

Initially powering up the vacuum can cause the circuit breaker to trip because vacuums can draw a lot of power. If the breaker was tripped first start by checking the breaker on the outlet. To reset the breaker simply pressing the reset button on the outlet. If the outlet doesn’t have a breaker then you may need to locate your circuit breaker panel and make sure the circuit breaker for that outlet wasn’t tripped.

On/Off switch not on or broken ¶ 

Sometimes double checking that the vacuum switch is simply on can help solve the problem. If the switch is push on, but the vacuum still won't power on it could be that the switch itself is broken and needs to be replaced.

Cord is broken or cut ¶ 

If the cord is cut or badly damaged this will stop power from getting to the vacuum. Immediately unplug the cord in order to protect yourself from electrical shock. It’s best to contact Customer Service at 1-800-798-7398 to talk about possible replacement and repair options.

Suction motor thermostat needs to be reset ¶ 

This vacuum has a thermostat to prevent any damage to the suction motor from overheating. This causes the vacuum to shut off until the suction motor has cooled down. In order to reset the suction motor thermostat the following steps need to be taken:

  1. Push down the switch to the “Off” position
  2. Unplug the vacuum
  3. Check for a clog or obstruction in the hose or filter; unclog the hose and replace the filter if needed
  4. Wait 45 minutes for the vacuum to cool down
  5. Plug the Vacuum in; push down the switch to the “I-On” position to start the vacuum
  6. If the vacuum still does not start, contact Customer Service at 1-800-798-7398

Loss of suction ¶ 

The vacuum does not pick up any dirt when being used.

Dust Cup Full ¶ 

If the Dust cup is full, there is nowhere for the dirt to go when vacuuming. To fix the problem, remove the dust cup by the handle at the top and empty the dust cup.

Filters needs cleaning ¶ 

If you haven’t washed your filters recently, it may be why your vacuum has lost suction. To clean the filters, remove the dust cup and pull out the 2 filters that sit below it. Then remove the HEPA filter at the face of the vacuum by lifting the latch holding it in place. Rinse the filters with water until the water runs clear. Let the filters dry completely before putting the back in the vacuum. If the vacuum still doesn’t pick up dirt, you may need to replace the filters. Check out the HEPA Filter replacement guide and the Foam Filter replacement guide.

Blockage in the vacuum ¶ 

If the vacuum is not picking up any dirt or debris, there may be something blocking the airway.

There are three main areas that you can check for clogs:

  • Behind the brush roller
  • The hose
  • The dust cup air duct

To check for a clog behind the brush roller:

  1. Lay the vacuum down
  2. Use a Flathead screwdriver to turn the latches holding the hose opening in place
  3. Check for a clog around the area where the brush roller spins

If there is no clog there, the next step is to check for a blockage in the hose:

  1. Press the handle release button to access the hose attachment of the vacuum
  2. Check for clogs at both ends of the hose

Lastly, check the the dust cup air duct:

  1. Remove the dust cup
  2. Check the air duct behind it

Suction Motor is going bad ¶ 

Its best to make sure there are no clogs in the hoses or underneath the panel where the roller brush spins and the filters are clean. If none of these solutions solve the problem then its possible the suction motor may be going bad. Its best to contact Shark to talk about your options for replacement or repair.

Roller brush is not spinning ¶ 

The vacuum has power but the roller brush is not spinning

Roller brush switch is off ¶ 

Check to make sure the vacuum is switched to the correct mode. The switch should be in the Power and Brushroll mode to make the roller spin. If it is in just the power mode the roller will not move. The brushroll indicator light should be green when working. The brush will only spin when the vacuum is tilted back. If the vacuum is still not working the switch that detects if the vacuum is tilted back may need replacing.

Debris on the brush ¶ 

Remove debris from the brush to allow motion. The debris may be pieces of string or hair wrapped around the brush restricting movement. Unplug the vacuum and use scissors to cut the debris from the roller and pull it out with your hands to allow the brush to spin.

Disengaged nozzle ¶ 

For the roller brush to spin the nozzle needs to be completely attached, even if the vacuum has power. Make sure the connection is tight by pressing down on the handle to improve the connection. If that does not work, unplug the vacuum and disconnect the nozzle. Remove blockages and debris from the nozzle. Reconnect the nozzle before turning on vacuum again.

Broken Belt ¶ 

The belt is used to spin the roller brush. If the roller is not spinning the belt may be broken or worn out and needs replacing. Use the Roller Belt replacement guide.

Wheels are not working ¶ 

The vacuum will not roll across the ground

Debris is in the way of wheels ¶ 

If the wheels can still move but are very rough and hard to push, try examining around the wheels for hair, dirt, or some other item that could be locking one or both wheels in place and creating resistance. If there is no visible blockages, try pulling the wheels off and further inspect them along with testing to see if they will spin freely while removed. If not, and there are no visible blockages, then the wheels need to be replaced because there bearings could be old and stuck.

Pin is bent ¶ 

If the wheels do not move at all or are very hard to push then it could be that the pin is bent. Remove the bottom panel from the vacuum and look at the wheel pin for damage or bends, including damage to the plastic around the pin that could be obstructing the wheel from turning.

Vacuum won’t stay standing up ¶ 

The vacuum handle falls when left straight up

Latch is Broken ¶ 

If the vacuum will not stay up, check to make sure it is being lifted all the way up to its locking point by pushing the handle toward the front of the vacuum until it stops. If the vacuum continues to fail you should check the latch by taking off the top panel of the vacuum and look for obstructions or broken plastic in the vicinity of the latches and make sure the latches are still there and functioning.


my vacuum wont pick up spits everything out. I check bottom and hose nothing is clogged?

piece of junk, less than a year old and the roller won't work. I checked the belt, it's intact, the motor and roller aren't bound up, they move freely yet the roller won't spin despite the green indicator light being on. JUNK. I checked the harness connecting the motor to the board etc, just stopped working, JUNK. If it's a broken sensor or bad wiring... screw this Shark brand junk, never again. WORTHLESS JUNK.

Yep. And nowhere is there any help to fix it.

Nick Arellano -

Same. Roller just quit. Guessing there are no options?

Joe Matthews -

All 3 brush position lights are flashing on mine today. Trying to figure out the cause and or solution.

Asif A. -

Mine is less then 2 months old and I’ve already had to have the brush roller head replaced. $35.00. Shark does this on purpose so you have to spend money. Now I’m facing the same issue a week later, will the new roller head. Only this time it’s $75.00 for a new roller head. They intentionally made it this way so you couldn't fix it yourself.

shark nv22ln26 beater bar spins when first engaged and then stops. I dismantled and cleaned head unit and it still spins when cleaning head is pushed down and then stops. I suspect switch that engages beater bar may be defective or sticking.

Losh - Reply

Mine does exactly the same; cleaned blockage. As soon as the roller switch is engaged it runs for a few seconds and then cuts out and the light turns red.

Check for a clog in the handle

Stacy Pence -

Mine was doing the same as everyone else said. I realized there was a clog in the handle. Once I cleaned that out, it now works like new.

Stacy Pence - Reply

I had checked the flexible hose on my machine, but, after I saw your post I detached the tube from the handle, and saw a blockage there. Thanks.

Maurice Jeter -

My rotator brush spins only when the vacuum is standing upright, as soon as you tilt it back the power to the motor cuts out. there is no clog or resistance to the brush, it’s clearly an electrical issue. anyone have any idea what’s wrong or how to fix it? email me @

Lee Spencer - Reply

Hi, me too.. We’ve taken it apart and all was well. Like you, the brush will turn when it’s at a standing position.

laelpowell -

We took the vacuum apart, nothing wrong. My vacuum also will run the brush bar when it is standing, and as soon as I push the handle part back, it stop.s.

laelpowell -

Beeter brush will only activate when the vacuum body is tilted to the right. The green light stays on when I’m active position. Odd. Email me if anyone knows what I can do to fix it.

My shark rotator professional roller will not stay engaged, i’ve checked the roller and belt they are fine, when I press the brush roll button if it engages it does not stay on if it even engages the brush, any suggestions??

Tim Crutchfield - Reply

I fixed the Shark. Brush was not spinning. Had to take it apart a few times and check internet suggestions. The switch was not “clicking” that indicates that the handle was pulled out of the upright position. As soon as I loosened the small green switch assembly from the white plastic holder, something let loose and the switch began to click as needed. This fix requires the small front wheels to be removed as there are screws behind them. 8 screws total I believe to seperate the brush assembly. Also easier to do this repair with the brush assembly disconnected from the power head.

Did the same thing - it worked! (but I’m not really sure why that switch would stick. Thanks

Barton Torbert -

I fixed the Shark. Disconnect brush assembly from the handle. Remove all screws to separate the plastic brush assembly. Including the two screws behind the small front wheels. As soon as I loosened the small green switch from the white plastic frame, the switch began to “click”. This switch let’s the vacuum know that the handle is pulled back and not in the upright position.

jjzsnowski - Reply

Can you send pictures of the small green switch? Is it in the roller assembly, or some where else? I’ve taken my vacuum apart several times. I tried loosening the small green assembly in the roller section, but no roller activity. I am definitely getting suction, but no roller activity.

Joanne Fuller -

Thank you, rewired and took switch out of the circuit. Works once again.

Wayne Reeves -

What causes a vacuum not to bend. Worked ok earlier.

What causes Sharkie DLX not to bend? Work ok earlier.

Olivia - Reply

Turned the vacuum off to empty the canister. Reattached it and the roller brush would Not turn. Took it apart; no clog, clean roller brush, belt is fine, switch is on, wand is attached securely, canister is attached securely, all filters are clean… and it still doesn’t work. Hey SHARK….. does anyone over there have any answers?

Jim Leonard - Reply

The switch to activate the brush motor when the handle is lowered from full upright position fails. I fiddled with it (cleaning and such) and got it to work intermittently. Them I removed the switch, connecting the wires permanently. This works ok as we now just use the brush switch next to the power switch. I suppose you could order a replacement, but I needed mine to work that day. Good luck!

Chuck Fields -

My vacuum will not stay stood in the upright position, the only advice given on here is to check the latch is broken, I can hear it clicking into place but it still won’t stay up.

you cannot see the latches anywhere unless I start taking it apart, this is only 3 months old and surely it should be better built than this

What happends when the suction motor goes bad? Do I have to buy another one? Or can i fix it?

angelbabylucy - Reply

When my vacuum is powered on but standing upright it acts like it is dead. If I disengage the body from the floor piece the beater brushes start to roll and it kicks in, though it is definitely not as loud as it used to be like it’s only half working? But if put it back in the upright position, like you would to use the wand along the wall, it does nothing?? I’ve cleaned out every single hose and the filters and it still doesn’t work in the upright position???

Jenn Krouse - Reply

I am having his same issue, did you ever figure out what was wrong?

Megan Whipple -

My vacuum start d making a noise it never made before like air was releasing and there is no suction. I cleaned all the filters and also checked all the hoses. Help!!!!

Sharon Otero - Reply

I love this vacuum- never had a problem in about three or four years until now.. Brush roll indicator light went out.. working fine before my daughters graduation party and to clean up, not happening. Completely sucks because I don’t have the funds to fix if I can’t do it .

Tamera - Reply

All of a sudden when I engage the roller it trips the circuit breaker. Never did it before. The vacuum starts fine in the upright position, use the foot to set the vacuum tie work oops tripped the circuit. I can use the hose with the floor/carpet attachment, but that doesn't do the job of deep cleaning. Anyone with the same problem? Next step is to check out the vacuum's electronics
