what is the deal with ballast pumps -Mine-one and done

Tried filling the stock ballast on the v215 today for the first time. All three tanks filled fine but only two emptied. Starboard pump blew. Switch still works (lights up) but pump is silent. Then circuit breaker thingy/reset button pops. So I assume it is a bad pump. I think this same thing was going on when I first picked up the boat from the dealer-(dealer replaced one of the pumps the day I picked it up)-so maybe these pumps have been sitting around a boat lot for a year and just get fried when they are first used.

I assume I got water still in right side tanks. Any way to drain the tank manually/gravity? I sent an email out to the dealer for info on a replacement pump-how many pumps do you guys blow through per season? I told my kid to take some pics of the wake-not much weight in the boat -it looks a little unruly-may need work.
