Why is the Shark battery/vacuum light flashing? - Ready for DIY (2023)

Your Shark vacuum has a few different lights that tell you if it's working properly. If a light is flashing, it usually means something is preventing the vacuum from working.

If the Shark Vac light is flashing, it means the brush roll is not rotating. Red lights could mean the brush roll is stuck or the vacuum is overheating. Flashing headlights could mean the vacuum is not in carpet mode.

There are a few different types of lights on the Shark vacuum. Knowing what each type of light means is critical to knowing how to repair your vacuum cleaner. If you know that a red light could mean it is overheating, this will save you some troubleshooting time.

Shark Vacuum Brush Roll light is flashing

Your Shark vacuum will have a light on the vacuum head. This light lets you know when the brush roll is stuck or not working properly. Sometimes there will be a pair of headlights instead of a small light, but they will work just the same.

What do the red lights on the Shark vacuum mean?

If the light is flashing red, it could mean two things:

  • The vacuum is overheating.
  • The brush roll is stuck.

If you've been vacuuming for a while, the light probably means the vacuum is overheating. If you've just started vacuuming or can't even start because the vacuum won't work, it's probably the brush roll.

Problems with the brush roll often prevent you from vacuuming because it doesn't spin when the lights are flashing; therefore, it should be easy to identify what the problem is.

What to do

If you think the vacuum is overheating, turn it off and let it sit for about 45 minutes. After it cools down completely, try vacuuming again. If the problem is overheating, your vacuum should work fine.

If the brush roll is stuck, turn the vacuum over so you can easily see the brush roll. The roller is likely to become tangled with hair or carpet fibers. Remove anything that is tangled around the roller. You can use scissors if necessary, but be careful not to cut the bristles or damage the machine.

Also clean around the brush roll. If you see debris caked in the cracks, clean them out.

If your vacuum is still not working properly after trying each of these options, try the troubleshooting steps listed at the end of this article.

what it means

When your vacuum cleaner's headlights are flashing, it usually means there's a traffic jam. This is usually accompanied by a non-rotating brush roller.

What to do

Press the Access Brushroll buttons to open the door above the brush roll. Remove the door and push it back into place until you hear a click. Both sides of the door must be secured in place.

Then make sure the floor setting is set to Carpet mode. Tilt the vacuum and turn it on to see if the brush roll rotates.

If that doesn't work, try the troubleshooting steps below or consider calling the manufacturer.

Shark vacuum carpet and floor lights are flashing

Most Shark vacuums have specific buttons for carpets and hard floors. These buttons will flash to indicate that something is wrong.

what it means

Flashing lights on the floor and carpet can mean two different things:

  • Flashing is switching between the lights:The vacuum is clogged somewhere and is preventing airflow.
  • Lights flash together:There is a problem with the battery, either the charger or the battery itself.

What to do

If the lights alternate, allow the vac to cool for about 45 minutes. Once it cools down, clean the vacuum following the steps in the troubleshooting section below. After cleaning it, test the vacuum. If it still doesn't work, you may need to repair it.

If the lights flash at the same time, it is a battery related problem. Allow the battery to cool completely as it can overheat. After the battery has completely cooled down, allow it to fully recharge.

Test the battery when it is fully charged. If you're still having issues, it could be a problem with the charger that will need to be repaired or replaced.

Read the Manual

Most manuals will list common problems and troubleshooting methods. If your Shark vacuum's lights are flashing, read your manual to see if it fixes the problem.

turn off and cool down

Allow the vacuum to cool completely before attempting to clean or test it. Overheating will cause the vacuum to temporarily stop working, and sometimes cooling it down is the only step needed to get it working again.

Forty-five minutes should be enough for the vacuum to cool down completely.
