Hello I got a grobo notification it is time to change water. I tried to drain the unit and the water does not drain please advise
I recommend opening a ticket with Grobo Support.

it is not empty … I have tried rebooting … I wrote grobo an email. When i say drain it just slowly dribbles out after about 20 it says its empty but it is not. I maybe drained 15% of total H20

The sensor on the back right is blocked or something is touching one of the 3 sensors
They look like flaps or folding handles

Roots dont look good, please dont look at them anymore they dont like light.
Can you check that clear plastix cover on th3 back right side and make sure those arent stuck. Thats likely your reason

Ticket would be my next move as maybe the pump died. Mine has died before and had to replace it.
