HELP!! - Return Pump Stopped Working

[g6gang]

My Speedwave DC 790 - just decided to stop working (had it less then a year). I had it hooked up to my Reef Angel (using Jabeao cables) and it was working fine but seemed like it was not going full throttle, so I turned it off using Reef Angerl controller then back on - and it wont turn on. I then unconnected ReefAngel Jebao and put the original Speedwave Controller back in. It is getting power, but the motor does not spin. I also tried pressing feed mode and still no go - alsmot seems like it is stuck in feedmode or is in some weird state.

Any ideas to get it running or should I just toss it...Right now my backup pump is about half the GPH (and not controllable) - Should hold me over till the morning until I decide what/how to replace -

Try soaking it in vinegar. Check the impeller for corrosion or if it broke

OK I will try that. I was able to take impeller out and clean it. It seems like in good shape. It seems like it is held in with magnets. I don't even feel any vibration. That's why I though it may be stuck in feed more. Not sure if there is any secret combo on keypad to reset
