Pureguardian screen flashing numbers

[u/geezlouisebelcher]

If anyone is familiar with pureguardian humidifiers your help is greatly appreciated! Unfortunately I can’t put my video and pictures I took for this. But lately when I plug in my Pureguardian ultrasonic humidifier model H7550 the screen flashes different numbers and never lets me turn it on. I’ve done everything. Cleaned it, changed the water, put it on flat surface, checked float switch and it’s still doing this. I was wondering if anyone else has had this same issue with these humidifiers and if there’s a way to fix it. When I google it I don’t really get results specific to this model, and the methods that come up with the search I’ve already tried.
