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.
