Red Light on Rainbow E2 Black!? Why?

Red Light on Rainbow E2 Black!? Why?

Is the red light on your Rainbow E2  vacuum coming on? In this video we go into some common problems that cause this model to stop working, and the solutions to those problems!

Important Safety Tips

  • Always make sure your machine is unplugged and the power button is turned off, before servicing your vacuum.
  • Always make sure your hands are dry and free from moisture before servicing your machine.
  • Be sure to wear gloves when servicing your machine to prevent any cuts or scrapes.
  • If you are uncomfortable working on your vacuum, please don’t hesitate to contact us at and we can help you through the process or you can send it into us to fix it for you. 


  • Flat head screwdriver


Gather the following four components: the canister, the main wands, the power nozzle, and the main electrical hose. Any one of these four could be the problem and the reason why the red light is coming on.

The first part you will check is the main power hose to make sure that it’s connecting to the vacuum cleaner properly. If there is anything blocking the prongs at the end of the hose, or if those prongs are bent, it will cause a bad connection and the red light will come on.

Also, take a look at the grey tabs at the same end of the hose. These attach the hose to the vacuum, so if they are broken or damaged the hose will not latch properly. Additionally, if the holes for these latches are damaged, broken, or blocked the hose will not be able to latch properly.

If these appear damaged, you can email us at and we can help you with repairs.

To plug the hose in, lift up the flap for the electrical port and then firmly press the hose into place. You should see both grey tabs lock into place and you will probably hear it as well. It may help to apply pressure to one side and then the other as you connect the hose to the vacuum. If the hose connects properly you can move on.

The other end of the hose is one of the most common reasons for the red light to come on. Usually it is because the trigger lock is engaged. If the grey lock is all the way down it locks the trigger in the “on” position. If it is all the way up it prevents the trigger from being pulled at all. If it is in the middle/ neutral position you will be able to press the trigger on and off. If the trigger lock is all the way down and you are trying to turn your vacuum on the red light will come on.

Make sure that the trigger lock is in the neutral position – you can tell if it is correct if you can move the trigger freely.

Now, check the very end of the electrical hose – make sure it is not damaged and is still round. Also make sure the button lock is sticking out and working properly. Check the electrical connection and make sure there is no dirt, debris, or moisture on it.

If that looks good go ahead and check both ends of your wands for the same things! Make sure the electrical connections are clean and the prongs are not bent. Also make sure that the wand is still round and has not become bent.

If it looks good, insert the first wand into the hose and you should hear a click to let you know the button lock engaged. Repeat with the next part of the wand. If it all connects together with no excess play you should be good to go.

There is one more connection to check: the power nozzle. At the top of the nozzle is a pivot piece where the wand connects. There is a hole on the front for the button lock on the wand and an electrical connection at the top. Take a look at the electrical connection to make sure it is clean and not bent or damaged.

If it looks good go ahead and connect your wands and hose. Line everything up correctly and it should lock into place. If everything connected properly you don’t have problems with this part of the vacuum.

If any of these connections are not engaging properly go ahead and send us an email at and we can help you troubleshoot it further.

The next step is checking out the power nozzle itself.

Disconnect the wands to make it easier to check out. Take a look at the bottom and you’ll see the brush roll and a round brush on each side. If there is a blockage around the brush roll, like a sock or an excessive amount of hair, that could be the issue. The red light will turn on if the brush roll cannot spin freely. Go ahead and turn it by hand to make sure there are no problems.

If that part checks out okay, you can go ahead and take the cover plate off the bottom. There is a grey twist screw at the back that you can turn with a flat head screwdriver to unlock.

There are four tabs, two in the middle and two at the back, that you need to unhook to get the cover off. Push the tabs on the sides, one at a time, as you lift the cover a small amount.

Once those are free you can push the tabs on the back in at the same time and lift the cover off.

Once you remove the cover you can check inside for blockages and check that the belt is not damaged and can spin freely with the brush roll.

To replace the cover snap it back into place and don’t forget to turn the lock screw.

Connect the power head, wands, and hose to the vacuum and try turning it on to see if the red light still comes on. Use caution when the vacuum is plugged in – do not stick your fingers or anything else in or near the power nozzle! When the vacuum is on you should be able to look under the power nozzle and see that all the brushes are all spinning.

If the red light is still on and the vacuum is not working, send us an email at and we will help you troubleshoot it even further.
