Contact GHD asap. That's how I knew something was off with my straightener. The first time it happened the same thing to me, I turned it off, removed from the plug and waited and tried to turn it on again but I still get the red light flashing on and off. I tried doing it for a few times but still had the same issue so I contacted GHD and they replaced my straightener but after a few months it happened again. It sucks because for the price we pay for these straighteners we expect quality but unfortunately it isn't the case with these products.
