Dyson Cool Autoreact TP7A
Question about Dyson Cool Autoreact TP7A
why does my purifier make a high pitch sound after being turned on for a while, sometimes it takes days sometimes after only a few hours, needs to restart it every time it happens really annoying
Mine is not old either and I only use it at night in 4-hour sleep mode. But I have never noticed a high-pitched sound.
Mine is only 2 months old and doesn't make any high-pitched sounds yet.
Have you looked at the filters? If they are occupied, that would make sense. Take the hoover and suck them out from the back.
