First, If there was a zero stars review, they would have earned it with flying colors.
Trying to figure out what error H2 means on the AM09 fan heater, many emails and phone calls and it is apparently a company secret to either make you throw the old one away, or take it to a service center only to get screwed by their non-friendly, no phone call answering people, and no answering machine. It took over 5 emails and still I get the stupid answer which I stated in my first email that all I need is the meaning of the code H2, and I have done EVERY step they propose, so unplugging it and replunging it, was done days before my first email.
However, clearly their online people do not read what the customer writes because they are more intelligent and the customer is stupid enough to pay $700 for a fan/heater, they will be stupid enough to need to be told to unplug and replug or take it to the service center where they will screw you into outrageous repair charges that can only be done in the back so the customer won't know anything.
Save your money and try any other brand, it will be an UPGRADE to Dyson's repair series of unprofessional and disrespectful lies and ignorance.
