Just opened my cabinet and noticed the “W” on the controller, will flash red. Why is this?

How long have you had the pump? And is it red or orange? I know orange is an indication that the pump is not calibrated. Is the pump still operating properly, just has a flashing W?

Pump is four months old, (replacement unit bought from a member) and it is actually orange now that I look closer..

How do you calibrate it, And does it really matter?
