Set up my sump and my brand new Jebao DCP 18000 controller won’t let me adjust the flow. It worked fine last night, adjusted speed up and down, no problem. It is not locked. I can press for 3 seconds and it flashes to indicate it is locked or unlocked like it should, but will not allow me to adjust. It did not get wet. I can press any button and the dimmed display gets brighter, also like it should. I am stuck on minimum flow and can not increase it. I have pressed it softly, and pressed it hard. I’m about to grab a hammer and see if I can teach it a lesson!
