Like all other home appliances, resetting or rebooting may be the first thing you think of when your Dyson fan has operational difficulties.

Dyson fans aren’t any different.

You may have connectivity issues or just an unresponsive fan. Either way, resetting will be necessary to get it back up and running.

Here’s how to reset your Dyson fan:

  1. Locate the power standby ON/OFF button on your remote and on the fan.
  2. Press both at the same time and hold for 10 seconds. The fan has a home screen that displays a countdown to help you as you wait.
  3. Once the reset procedure is complete, you should see the screen display fan speeds again.
  4. From here, you can proceed to set your preferred settings.

How To Reset a Dyson Fan After a Filter Change

Changing the filter of a Dyson fan is a great way to ensure that it is running at maximum efficiency.

However, you may find that after changing the filter, the fan flashes an error code F. This usually means it is time to reset your Dyson fan filter indicator light.

Step 1: Locate the standby on/off button on your fan. Typically it is on the bottom half of the fan.

Step 2: While the fan is still on, press and hold this button down for six seconds. The screen will help you with the countdown during the resetting process. The fan will turn off and then back on again.

Step 3: Once the process is over, your fan is ready to use again.

How To Control Dyson Fan Without Remote

Dyson fans come with a magnetic remote control that sticks on top of the fan.

Sometimes, it might get misplaced or lost, and controlling your fan without it can seem like it’s impossible. But with a little bit of troubleshooting, you shouldn’t have any issues finding out how to do so without that pesky little remote.

Step 1: Turn on your Dyson fan using the standby ON/OFF button on the appliance (often on or near the bottom).

Step 2: Press the ON/OFF button to turn the fan on or off.

Step 3: Adjust the temperature using the temperature buttons/gauge. The temperature may first increase to the maximum before declining.

Although you can change the temperature, there are a few things you can not do without the remote.

For instance, you probably can’t change the fan’s speed or operate the sleep timer function.

Dyson Fan Not Blowing Air

Sometimes you might turn on your Dyson fan and hear that familiar hum, but nothing happens.

It usually means it’s not blowing air.

Don’t worry: as one of the most common problems with Dyson fans, there are solutions available to fix this issue.

If this is the case, there are only a few possible explanations for why it’s happening.

First, it could mean blockages in the loop amplifier blades or the air intake hole of your fan. To solve this, you can vacuum out the dirt and debris from the intake holes.

However, if you use the fan for heating and cooling, the dust attracts moisture, and vacuuming may not help.

You might need to disassemble the bottom part and clean the fan.

Another reason for a Dyson fan not to blow air is insufficient electric flow. In other instances, it could be a failed mechanical component. In both cases, contact a technician for further assistance.

For most people, this problem is beyond the scope of personal expertise.

Dyson Fan Blinking Codes

When Dyson fans fail, they will blink error codes on their display screen.

These codes can help you understand the exact problem with your fan. Let’s go over the most common codes that flash on your screen and how to fix them.

Dyson Fan Blinking F

Your Dyson fan will often indicate a blinking F after changing air filters.

It is a filter indicator light and won’t go away until reset. In order to reset your filter indicator light, hold down the power standby button on your fan or remote for six seconds.

Remember, the fan must first be on before resetting.

Dyson Fan Blinking F2

Another error code that you might see is F2.

It means that the fan’s UV-C emitter has an issue. It could also mean there is low power going to the appliance, or basically a power loss while it was still working.

Unplug it and leave it for sixty seconds. After that, plug it back directly into the main wall socket.

If that doesn’t work, opt for a hard reset.

Press and hold the power standby button on the remote and unit for sixty seconds while it is still on.

You also need to reboot your Dyson fan if you get a blinking F3 error.

Here is a good 1-minute video that shows you what to do to fix it:

Dyson Fan Says E

Sometimes when you try to use your fan, you may see a flashing E on the display screen.

This is another one of the most common problems with Dyson fans.

That means it is unable to perform a function as requested. Other times, your fan may display a solid E. This usually means the fan was functioning correctly but has since stopped.

Unplug the fan and leave it for about ten seconds.

Firmly (but safely) plug it back into the socket and then switch it on. Also, ensure that the room temperature is above five 41 Fahrenheit.

If it still doesn’t blow air, check for a blockage in the loop amplifier outlet and inlet grille.

Your filters may also need replacing if they have been in use for a long time.

Dyson Fan Says H2

You might get an H2 error code if the Dyson fan is trying to run on heating mode and there is too much resistance.

It could be due to dirt, which has clogged the filters, air inlet, and outlet grills.

To solve this problem, clean the grills under running water and ensure they are dry before plugging the fan back in.

Also, replace a dirty filter.

Dyson Fan Says 999

You might see PM2. 5 and PM10 levels indicated as severe followed by a 999 error code.

It sounds catastrophic, but no need to panic.

It’s unlikely that the air in your fan is filthy. The error is typically due to a clogged sensor.

To solve the error, locate the sensor. Unplug it and clean it with a brush to remove all dirt, debris, and foliage.

You can also use a can of pressured air.

Dyson Fan Won’t Connect to Wi-Fi

Have you purchased a new Dyson fan recently, and it won’t connect to your Wi-Fi?

Perhaps your old one stops connecting as well. The first thing you should do is ensure that the Wi-Fi is on.

Next, make sure that your fan is not too far from the internet router and that it’s connecting to a 2.4GHz network.

Additionally, check if your network is the problem by trying to connect other devices.

If that does not help, you might need to reset the WIFI configurations on your Dyson fan.

Press the standby ON/OFF button on the fan and the remote for 20 seconds. After this, the WIFI symbol on the fan should alternate from green to white.

Dyson Fan Making Noise

Although Dyson isn’t entirely silent when operating, some noises should concern you.

For example, a clicking sound when switching from front to rear airflow is usually harmless. On the other hand, other sounds can indicate problems that may exacerbate if left unchecked.

Here are a few fan noises to check out.

Dyson Fan Making High-Pitched Noise (Continuous Monitoring Noise)

A continuous monitoring noise happens when the fan relays data about the indoor air.

Normally, the fan comes with sensors that help with airflow and continuous monitoring of air quality, humidity, and temperature.

Even when turned off, these sensors continue running. But they should not cause any audible disturbance.

There may be instances where this fan makes high-pitch noise.

In this scenario, the fan is constantly seeking to maintain quality air in a room with open or leaky windows.

If the sound is a problem, you can opt to turn off the Auto mode.

Using the associated app, swipe up to reveal settings and tap open. Scroll down until you find the continuous monitoring button and open it. From here, you can turn Off the standby data collection option and click done.

Dyson Fan Buzzing Noise

Another sound that indicates a problem is a buzzing or grinding noise.

The sound results from accumulated dirt in the air filter or the intake holes, making it hard for the motor to work. If you have a model that doesn’t have a filter, simply open the fan and clean out all the dirt.

Consider checking for blockage from dirt and debris. If you have a model that has a filter, change the filter.

Dyson Fan Humming Noise

A humming noise is quite normal.

It is, in fact, a character of the appliance and should not worry you.

The noise comes from the thermostat as it tries to regulate temperature even on standby mode. If it’s intrusive, you could move the fan to another space, lower the speed, or unplug it entirely.

Dyson Fan Won’t Oscillate

It’s strange to find that your new Dyson fan won’t oscillate.

The problem often comes when you don’t remove the tape at the split section of the lower base body. It could damage the internal gear.

Another possibility is that there is a low power supply.

Make sure to plug it in the main wall socket (not the extension) and press the ON/OFF button. A LED light around the power button should light up.

Using the airflow controls, adjust your fan’s airflow speed. Now you can press the oscillation button to start the back-and-forth fan movement.

Why Does My Dyson Fan Turn Itself On?

Dyson fans come with a sensor and auto settings that help you schedule when to turn on and off.

It helps save energy and maintain room temperatures at a set time.

If it’s your first time to own a Dyson fan, this auto setting might be enabled. It turns the fan on in what seems like random off-and-on intervals. To fix this, use the Dyson app and switch to manual mode.

Then you can change the temperature and timing settings as desired.

Why Does My Dyson Fan Turn Itself Off?

Sometimes you will find that your fan shuts down on its own after a few minutes of operation.

This problem happens when your selected temperature (on the LED screen) is below the ambient room temperature.

Raising the target temperature a few degrees higher should solve the issue. Additionally, when the fun is in heating mode, it automatically turns off after nine hours of operation.

Why Does My Dyson Fan Smell?

There is a chance you will encounter an unusual smell from your fan.

It mostly is due to blockage in the appliance and needs a thorough cleaning.

Open and clean the inlet holes and loop amplifier blades for filterless Dyson Fans. If your model has filters, ensure they are clean or change them.

Why Is My Dyson Fan Flashing Green?

A green flashing light means that your WIFI is ready to connect to the Dyson app.

However, rapidly flashing green light could mean that there is a problem.

In this case, the green light means that the battery pack of your appliance is overheating. You should turn it off, unplug it, and leave it for ten minutes.

Basically, you reboot the fan.

When you turn your fan back on, the green light should no longer flash.

Why Is My Dyson Fan Flashing Red?

As you use your fan on the heating mode, you might notice a flashing red light.

That means the appliance is yet to reach the target temperature and is still heating. Once it achieves the target, it should stop.

Usually, a red flashing light is nothing to worry about on a Dyson fan.
