Powerless Dolphin Pool Cleaner!

Hello, my Dolphin has worked great for some time, but one day the power source started turning off, I push the button, it makes a little bit of noise and the switch turns off again, if I unplug the blue cable it will stay on as normal, but once I connect the Dol, it happens againn, I wold appreciate any insight.

Thank you,
