I have only had this new one for a few days now. The problem started with the controller turning off randomly. I thought maybe i had the plug in an auto outlet but it wasn't. Now the controller is flashing red green. The old error code was for a stall. I've checked both the dry and wet side and everything seems fine. When I unplug and replug in it starts off on the flow setting then immediately goes to red greed flashing. Any ideas?
