Hi everyone, So I purchased one D5 Next from Aquatuning in the US and it looked fine when it arrived. Fast forward a month, outside my return window, and the pump appears to be working but the controller is not. Whenever I plug it in via USB, there is no display or LEDs. Aquasuite does not detect it either. I purchased a second one from a different seller this past week and just received it. But it's having the same situation, no display, no LEDs, not detected. It's very weird that two in a row ...
