SE MN | I had the same problem quite often with my 4710 and that only had the brown box. On my 4720 did not have it happen last year and only had it happen once this year. I don't think the GS2 has anything to do with it because I just unplug the brown box and plug it back in and it takes care of it. I think maybe it resets it's self after you unplug it? I noticed it seemed to happen mostly after the sprayer sat and was not used for a while. It sure would be an easy thing to try. Has worked for me and also worked for a friend of mine, neither of us can figure out why, but it took care of it. | |
