Red Dragon 3 Speedy don't works - Controller has no lights


New member

this is my first post. I try to explain my problem.
I have a Red Dragon 3 Speedy (50W, 5.000l) since 2018. Cero problems until yesterday. Yesterday I turned off the pump to do some maintenance (nothing to do with the pump) in the aquarium. When I turn on the pump, it does not work, the controller display does not turn on. I power cycle several times, and it still won't turn on the controller. The pump is clean, because I do regular maintenance. It doesn't have lime or anything like that. However, I disassemble the pump again, and reassemble it. But the controller still won't turn on. I open the controller for the first time in 6 years, and I don't really see anything I can fix, or that is visibly broken, or looking bad. What I can do ? I am in Spain. I have to buy a new controller ?, and how can I be sure that the controller is broken and not the pump ?. I attached a couple of photos with the labels of the pump and the controller.
Thank you very much for the help.

Hi slief,

thank yoy very much for your answerd. I'm in contact with the service from Royal Exclusiv in Germany. I will send the pump and the controller, and they will see what is wrong, and they will change it (99% controller), only the circuit, not the entire controller. This is cheaper.
