Green/red is a "stall error". It just happened to me, not 2 weeks ago, with a brand new mp10 the first day i had. Actually the first 10 minutes I had it.
Power it off. Then remove the wet side. Now power back up, just with the dry side hanging on your tank. If it goes into the same error mode (mine sometimes took anywhere from 5-20 minutes to do it), call Ecotech first thing Monday morning, they will happily send you a replacement withing 48 hours ish and you'll send them back the bogus one.
If it runs fine without the wet side... well just call them. They'll take care of you. Their support is very good.
