Your machine may be hot to the touch if it has been used as a heater in the last couple of hours. Please do not touch the sides of the loop amplifier until it has cooled.

Retry machine at 32°F

On first use, the machine will default to a temperature 1°F higher than the current room temperature.

Thereafter, the machine will remember the last target temperature set.

The heater will not operate unless the target temperature is above the room temperature, or the target temperature is set to 32°F for cooling.

Please retry the machine at temperature setting 32°F.

Has changing the temperature to 32°F resolved the issue?

We're glad the problem's been solved.

Please let us know if there's anything else we can help you with.

Run the heater for 1 minute at the highest temperature setting.

Airflow

Ensure the airflow button on the main body is being pressed. If the remote control is not working but the button on the machine is, please select 'Remote control not working'.

Each time the heating mode is selected, it conducts a short calibration cycle. Airflow will be automatically controlled during this cycle and you won't be able to adjust this yourself. To check if the machine is in the calibration cycle, set the machine to oscillate. If it is in the calibration cycle, it will not oscillate.

Once the calibration cycle is complete, the machine will revert to the selected airflow speed and temperature, unless the temperature of the room is above the target temperature. You should then be able to adjust the air speed.

Has changing the air speed resolved the issue?

Enable cooling mode

Unlike the AM04/AM05 the AM09 does not need to be set to 0°C to enable cooling mode.

Turn the machine on.

To turn the heater off and use cool air mode press the BLUE Thermostat Control button. The power button light on the main body will change from red to blue.

Change the airflow speed using the Airflow Speed Control.

NB: The fan speed setting is between 1-10.

Normal oscillation speed

The oscillating speed is normal.

Is there anything else we can help you with?

Checking oscillation

The AM09 has a one touch smooth oscillation action.

When in oscillation mode the machine will temporarily stop oscillating when any of the control buttons are pressed.

If the oscillation doesn't work carry out the following checks:

Check the six feet on the base of the main body are present and clean.

(If the heater is placed on a low friction surface, e.g. highly polished or oily, the main body may slide)

Switch the heater on. Press the oscillation button.

Check the other remote functions are working and that the battery has not run out.

Try a 'Hard reset'. Unplug the machine at the wall and leave for two minutes before plugging back in.

If the other functions are not working send a new remote.

If the oscillation action is still not working arrange an exchange.

Has this resolved the issue?

Check remote

Check if the other functions on the remote are working.

If the remote control is not working but the button on the machine is, please select 'Remote control not working'.

Has this resolved the issue?

Test airflow

Switch the machine on using the remote control or button on the main body.

If the airflow control is still not working this issue can be resolved by arranging a return to base repair.

Press the airflow control button (2) at the top and bottom, whilst testing the airflow.

NB: The display will show 10 after the product has reached maximum, or 0 for minimum airflow.

Check the other remote functions are working and that the battery has not run out.

Try a 'Hard reset' on the machine. If the other fuctions are not working send a new remote.

Has this resolved the issue?

Check the other functions on the remote

On/Off

Cool air mode

Airflow speed control

Temperature control

Sleep timer function

Oscillation On/Off

Personal heating mode

Diffused heating mode

Do the other functions on the remote work?

More than 9 hours

Dyson fan heaters and hot and cool purifiers have a positive safety feature where the machine deliberately switches off after 9 hours of continuous heating.

If you would like to continue using the machine after 9 hours, you will need to turn the machine back on by using either the power button on the remote control or main body.

Has this resolved the problem?

Turn machine off

Please turn the machine off and back on again.

Has turning the machine off and on resolved the issue?

Check feet

The AM09 has a one touch, smooth oscillation action. When in oscillation mode, the product will temporarily stop oscillating when any of the control buttons are pressed. If the oscillation action doesn’t work carry out the following checks.

Check the six feet on the main body are present and clean. (If the heater is placed on a low friction surface, e.g. highly polished or oily, the main body may slide.)

Check remote

Switch the heater ON.

Press the oscillation button.

Check the other remote functions are working and that the battery has not run out.

Try a ‘Hard reset’.

If other functions are not working order a new remote.

Exchange required

If the oscillation action is still not working this issue can be resolved by arranging an exchange.

Has this resolved the issue?

Please check the following

Fuse in plug.

Household electrics.

Unplug the machine, plug back in and ensure the power button on the machine is being pressed fully.

Hold for 2 seconds.

Use the buttons on the machine, not the remote control.

If the remote only isn't working, please select 'Remote control not working' from the drop down list.

Has checking the power resolved the issue?

Change target temperature

The machine will do this if the previously entered temperature is below the current room temperature and above 32F.

Please change the target temperature to 32F and retry the machine.

Use the buttons on the machine, not the remote control. To use as a heater please select a temperature above the current room temperature.

If only the remote isn't working, please select the 'Remote control not working' from the drop down list.

Has changing the temperature setting resolved the issue?

Idle mode

The AM09 will switch into idle mode once the target temperature is reached, idle mode means the motor is running at a lower rate than when in use to keep air flow moving over the thermostat so that the machine knows when to switch the heating mode back on.

If you are near the machine they may feel a draft coming from the machine when it is in idle mode.

Machine is working

This is normal and the machine is working as expected.

Is there anything else we can help you with?

Machine is working normally

This is completely normal.

The machine will run very slowly when in idle mode to keep air flowing over the thermostat so it can constantly regulate the temperature of the air.

This is a characteristic of the product and cannot be resolved with an exchange or return to base repair.

There is no safety concern.

If the noise is intrusive, switching the machine off at the wall will stop the noise, or altering the position of the product in the room might make the noise less audible.

If pressed, it should be stated that the noise is caused by some of the electrical components emitting a frequency which can sometimes be heard as an electrical humming noise. This is not specific to Dyson products.

Is there anything else we can help you with?

Is this the first time the machine is being used?

Do not use detergents or polishes.

Checking the loop amplifier and shroud

Check the air inlet holes and loop amplifier for blockages and remove as necessary.

Use a soft brush to remove any debris.

To clean, wipe with a dry or damp cloth.

Intermittent power

If the machine has been constantly heating for 9 hours, please select yes.

Has the machine been switched on for 9 hours, or more?

More than 9 hours

Machine is working normally

This is completely normal.

The machine will run very slowly when in idle mode to keep air flowing over the thermostat so it can constantly regulate the temperature of the air.

This is a characteristic of the product and cannot be resolved with an exchange or return to base repair.

There is no safety concern.

If the noise is intrusive, switching the machine off at the wall will stop the noise, or altering the position of the product in the room might make the noise less audible.

Is there anything else we can help you with?

Reset the machine

Please unplug the machine, leave for a minimum of 5 seconds.

Plug the machine in and switch on.

Has turning the machine off and on resolved the issue?
