Bought this dryer Monday, was delivered Wednesday. Bought this heat pump dryer as i have the matching washing machine so looks good together. Used the machine three times and was excellent, on fourth use i could smell a faint smell of burning but just put this down to the machine being new, 20 minutes later bang, and lots of thick smoke pouring out the machine, fortunately i managed to switch off the power at the wall and then tried to comprehend what had just happened. Called Haier and was told an engineer would call me within 48 hours, got a confirmation email to advise that the engineer had been booked and would be in touch, decided to call the engineer as was nervous about an electrical appliance with a defect being in the house, engineer advised that they had not been contacted by Haier so couldn’t come out to look at the defect machine. Decided to contact AO, they are going to replace the machine, which is great. Happy with AO, not so happy with Haier’s customer service.
