    This is what I end up doing to fix mine. I take a cheap tooth brush with bristles all in a straight line. Not a fancy one with circles or designs in the middle. I than press that on the vent holes right under the Dyson wording and above the temp display. You can't miss them lol. Any way press the tooth brush into these holes and clear of dust. Do this all around the unit. Than I use compressed air to blow through the vents to clear or even deeper junk. After this is all completed it seems to work for some time before the error starts showing again. Which seems to go with the other comment the unit is not hearing to prevent a fire from a safety feature.

    If it comes up an ok there way I have cleared it is wait til the error shows than unplug it and plug back in and power it on again. Do this a few times and you it will work. Just takes patience also you will notice when the error will not display there will be a different sound and the fan will work pretty quick. I also tend to keep the fan speed speed around 4 when restarting don't know if this helps or not.

SOURCE: Hi. I have a Dyson AM05 fan heater purchased July 2014. Whilst the cold air works brilliantly the hot air doesn't work at all. It shows an error message E8. Any advice?

I suspect that the microprocessor detected an overheat fault and is keeping it in E8 mode to prevent fire. The code needs to be cleared somehow. If it has some buttons on the front then try holding one whilst plugging it in. This may reset it. The reset will be something along those lines. Don't open it because if you can't fix it that way you need to take it back to the shop.

My dyson hot and cold fan is displaying code C2 and won't turn on or off

quote from amazon site***Mine also showed H2. I had a suspicion that it was the remote causing it. Changed the remote battery (CR 2032), turned on the heater and let it circulate for 3 minutes, then I went and tested all remote buttons. It worked! No more H2 error code!

What does error code E8 mean on the dyson hot/cold fan mean?

Possibly it doesn't like the heat setting and shuts itself off to prevent melting or possibly fire. Be sure that it is not blocked so cold air goes in freely. Try to lower the temp setting and see what happens.

Dyson hot and cold

Hi there, it's Jack at Dyson.

It sounds like your heater is shutting off because the ambient temperature is higher than or equal to the target temperature you've chosen (shown on the LED display on the front of the machine):
The heater's intelligent thermostat is engineered to turn the machine on only when needed when the ambient room temperature drops below the target temperature. However, we're happy to help you make sure your heater is working as intended. Please give us a call on 0800 298 0298 (UK), 1-866-693-9766 (US), 1-877-397-6622 (CA) or 1800 239 766 (AU).

I just buy it and whene i plug it ,it gives code ou-80,h2-00

Your error code indicates that the Fuser is not at the correct temperature, which can lead to smeary smudgy copies or scorched paper and a fire hazard, depending upon whether the fuser is too cold or too hot.

Replace the Fuser Unit.
