Ballast Fills, Wont empty

Quick question. I have an 06 MC X2 and I this past weekend, my center tank would not empty. It fills just fine, does not seem to have missed a beat, but when I flop the switch to empty, nothing. It has always been on the slow side to empty, not as powerful as compared to the left and right tanks, but it has worked. Has anyone got an idea of what could be going on, quick fixes or what to look for? I do appreciate any help. I have searched this one to death, and cannot find anything specific to this situation. Thanks in advance. Brian

Generally the first thing to check is the impeller. But dont forget to check the battery terminals. Mine has been known to not work right if there is the slightest bit of corrosion on the battery terminal. Good luck!

I have had the same problem with my 06 X1. I opened up the impeller housing and ran it for a second everything was good. It is a black impeller as I am sure yours is. I have heard these can stick. So I'm guessing that is the problem. I think there is a green or blue impeller that can solve the issue. Does this sound right to others that have had the problem?

Yes.
