E08 on the Valley Pro / Pro2
An independent guide from FixMyPivot, not from the manufacturer. Brand and panel names are here only so you can find your own equipment.
What it means on the Pro2
Pressure sensor out of range low.
The panel does not trust the pressure reading, so this points at the pressure sensor or its connection, not the pump. A plugged sensor tube or ice against the sensor can cause it with nothing actually broken, most often in cold weather.
Call a technician for this one, rather than opening the panel.
What it means on the Pro
Pressure sensor out of range low, or no sensor fitted.
Causes a pressure fault on the diagnostics screen.

Safety
Center pivots run on high voltage and heavy moving machinery. Shut off and lock out power at the main disconnect before you open a panel or touch anything electrical. If you are not sure, stop and call your local pivot dealer or a licensed electrician. These pages tell you what a code means. They do not replace a qualified technician, and the safety instructions that came with your equipment come first.
