How To Fix Dyson Flashing Red Light 4 Times

Dyson Flashing Red Light 4 times Fix – I purchased the Dyson DC35 about 1 year ago, and I have been very happy with it until recently when it started flashing the red light 4 times in sequence.

At first, I ignored it because this happened once before but then went away after a while, but after looking on the internet I found that this problem was occurring more frequently

so I decided to take action and fix it myself rather than wait to see if it would go away or take it to the shop and pay them lots of money if they couldn’t fix it.

I wrote everything in the article so that you may be able to extract useful pieces of information out of it.

Use the reset button

Some common models of Dyson vacuums feature a reset button located on the main motor assembly. To use it, you’ll need to shut off your vacuum, unplug it and remove its casing.

Use a screwdriver to hold down the red reset button while plugging in your vacuum and turning it back on. If your machine still flashes four times when powered on, take it to an authorized repair center for service.

 Dyson Flashing Red Light 4 Times

Clean the dust bin thoroughly

There are some simple solutions to your flashing red light. The first is to make sure your machine’s dust bin is clean. Simply lift up and empty out any debris or tangled hair that may be residing in it; then, try turning on your vacuum again.

If you’ve successfully emptied out all of its contents, there’s a good chance you’ll still see your flashing red light. But don’t worry—it won’t last for long! You simply need to give your device a proper shake before trying to turn it back on.

This will redistribute all of its various components and reset the suction power level, allowing it to run properly once more.

Replace the motor protector filter

If your vacuum cleaner stops abruptly or flashes a red light four times, you might have a clog in your motor protector filter. This little guy is designed to protect your motor and keep it cool while running.

Remove it from its housing and check it for any signs of obstruction. A common sign of trouble with these filters is fraying at their edges; if you notice any rips or tears, replace them immediately to avoid further damage.

It’s also a good idea to blow out any debris you spot with compressed air (be sure not to point toward components). When everything looks clear—or as clean as possible—reinstall the motor protector filter and resume use of your vacuum. If it shuts off again, repeat the process until everything appears normal again.


Unblock filters if blocked

The most common reason for a flashing red light is that your vacuum cleaner’s filters are blocked. This usually happens because you haven’t emptied its dustbin recently, but could also be because it has been used to clean up pet hair or similar fibers.

Take out both of your filters and run water through them to remove any dust, hair, or other debris caught inside. If there is any build-up in them, get a toothbrush and some warm soapy water and clean away thoroughly.

Make sure you air dry them afterward (using a hairdryer may distort their shape), since they need to be completely free of moisture if they’re going to work properly.

Replace the battery

If your Dyson is flashing a red light four times, it’s not because it wants you to clean its container. It’s actually giving you a bit of important information: that your battery needs to be replaced.

Replacing it can be tricky, but if you’re familiar with small appliances, then you shouldn’t have any problems doing so yourself.

Make sure that you have all of your tools before beginning and follow our step-by-step guide above for guidance on how to replace an older battery with a newer one.

To prevent further issues with your vacuum and ensure safe vacuuming, we recommend performing regular maintenance of both your vacuum and filter.

The V8 model is a great vacuum cleaner and offers a little more than its V6 counterpart in terms of power and may face the problem of flashing red lights lesser than the other model.

However, with that comes a longer charging time. If you’re going to be cleaning all day long, then a long charge time isn’t going to be that big of an issue.

But if you just want something for your hard floors and rugs, you might find yourself recharging throughout your cleaning session or only using it on smaller jobs like weekly sweep-ups or areas that are small enough for one battery charge to last.
