Why is my Shark Vacuum Blinking Red?

In a normal situation, the Red light remains solid red, and may this is what you are used to. When it starts blinking/flashing, you may wonder what is happening, and such a question arises.

What does this mean?

When the red light is flashing, there may be two reasons; Either the brush roll is compromised, or your shark vacuum cleaner has overheated. Your shark vacuum cleaner can overheat when you have over-used it or even when the brush roll is jammed up and cannot rotate as intended.

How to Make Sure that your Shark Vacuum Cleaner does not Blink Red

It is clear that when your Shark Vacuum Cleaner is blinking Red, it means that it is not functioning well. It means that some of the parts of your vacuum cleaner are corrupted and may lead to a breakdown or cause further damage to other parts of the vacuum.

To make sure that your vacuum cleaner parts are not corrupted, here is what you need to employ;

  1. Deep Cleaning of your Shark Vacuum cleaners

Your shark vacuum cleaner cleans your floor and other surfaces; it also needs to be cleaned on a regular basis. You need to take time and clean your vacuum cleaner to make sure that there is no dirt build-up that may lead to clogging of the vacuum cleaner parts that may lead to the said errors and consequently malfunctioning different parts of your vacuum cleaner.

To achieve deep Cleaning of your vacuum cleaner;

  • Detach and clean all the attachments. This may include an upholstery tool if your vacuum cleaner is a handheld one.
  • Always empty the dustbin and clean it regularly. Make sure that you also clean the rest of the areas that the dust tank touches and any other opening that leads to the dust bin. This is to make sure that any dirt that may be attached to these parts is dealt with.
  • Clean the Hoses. Because the hoses have a strained passway, the dirt may tend to clog them. Use a thin string to knock the debris loose. You need to take care so that you don’t damage the hoses as you clean them.
  • Replace/Clean the Filters. The filters play an integral role in making sure that you breathe healthily as your shark vacuum works. Depending on the type of Shark vacuum cleaner you are using, you can either wash the filters (If washable) or replace them.
  • Always Clean the brush roll. As the brush roll maneuvers through your floor, some dirt may clog around it, and you need to clean it from time to time to prevent it from being entangled.
  1. Supply Power Properly

If your Shark vacuum cleaner is a cordless vacuum cleaner, make sure it is fully charged for better suction and vacuuming. When the battery runs low, the suction may reduce or may lead to an indication of different errors in your vacuum.

For corded shark vacuum cleaners, ensure the power cord is plugged correctly into the power supply sockets. You also need to make sure that the power cord is well insulated.


A little maintenance on your vacuum cleaner is needed for proper functioning. The basic maintenance you can carry on your vacuum cleaner is to ensure that it is also clean as it cleans your floor. 

Sometimes the errors may persist, and your shark vacuum cleaner may stop working or may reduce its efficiency. You may seek clarification of the user’s manual or contact your local vacuum cleaner expert.
