If this is your first H2 error, don’t worry, it’s easy to fix.

What are the reasons for Dyson Heater Error H2?

As H2 is a common error code, it occurs in many appliances. Because of this, there are several different reasons that may cause you to see this code

It could be because of clogging filters or the fact that the heating element becomes dirty over time.

These can be caused by things like pet hair and dust collecting on top of the filters.

It can also sometimes be caused by the heating element becoming dirty, following a build-up of dust and flint.

If your Dyson heater is making a humming noise or not heating up, there may be something wrong with the fan motor. Luckily fixing this issue is easy and doesn’t require any tools.

With just a few simple steps, you can get back up to speed with using your Dyson heater in your home again.

To start, you’ll need the following items.

  • A high PSI can of compressed air

How to reset a Dyson heater?

This is a quick and easy fix for your machine. All you have to do is turn the power off (using either the on/off button), wait 60 seconds then turn back again.

Why does a Dyson heater turn itself off?

Dyson heaters have a built-in thermostat that you can set to. The heater will then automatically switch itself off once the room reaches your desired temperature.

If it detects any temperatures below what is optimal for cooling, then this clever device will automatically come back on.

Dyson fan heaters also have a safety feature that allows the heater to switch off after 9 hours of continuous use.

The Dyson heater has a built-in timer which can be adjusted from 1 hour, 3 hours or 5 hours.

This is especially useful if you plan on having the device switched on for an extended period of time.

What to do when your Dyson stops working?

It’s not uncommon for Dyson heaters to overheat and cut out if they’ve been in use for a long time.

If your machine loses power, just leave it be for half an hour before try switching it on again.

Dyson fan heaters are designed to protect themselves from overheating, which means they’ll automatically shut off if it has been working for an extended period of time.
