Ha! Ok basically I had to take the Grobo apart follow the fill line to the pump and got what clogged it out of the pump, if you’re not mechanically inclined I wouldn’t attempt it I suggest if that happens get help from someone with skill

Do you know what kind of fitting the drain hose is connected with, quick connect, hose clamp, etc? I fix cars for a living so grobo diagnostics shouldn’t be too tough. Only concern is getting res tank out, I took the case (white outer metal) off once to fix an issue but did not think to check pump. @Wolf1 Do you remember how u went about disassembling to access/remove pump line? Don’t really want to remove res tank full of water. I’m also confused as to why app told me drain went through successfully but it did not, shouldn’t water level sensors know where water is at? @Stephen @bjorn

No all you do is remove the right screws from the back and move the side panel you can access the pump from there

@Wolf1 thanks I took back off once already. Figured it out:sunglasses: so during shipping my lower float sensor must have unplugged 
. Plugged her back in, performed drain and fill successfully 
thanks for all the help trouble shooting!! @Stephen for the win

I have been having some glitches like not draining or filling and most often not being able to start a new grow.
My app kept telling me to reconnect to wifi but it was already connected.
Eventually I got them all to work with a little unplugging, restarting, reconnecting, and repeated tapping.
I don’t know if it will permanently fix things though.
