I love this fountain water bowl and so do my animals! Whenever it comes time to change your filter, just press the button four times. You should hear a ringing, not a beep. The blue light is the indicator that the filter has been replaced. I am telling you this to save you the trouble I went through when it came time to replace the filter. It was user error. Thank goodness for the stellar customer service! I highly recommend this product!
