Mine was beeping for the filter to be changed so I took it out and cleaned it. Now it will light up for 1 second but goes into limp mode. Won’t do anything after that.
Could you tell me the model of the product you are using if it is convenient? Maybe you can try to look through the product manual, you should find something like this [After changing the filters, please press sleep button for 3 seconds to reset.] 🤣
