Valley Pro / Pro2 error codes
An independent guide from FixMyPivot, not from the manufacturer. Brand and panel names are here only so you can find your own equipment.
28 listed for this panel. Tap one for the full explanation. These only apply to this panel. On a different panel the same code, light or message can mean something else.
This page covers two panels, the Pro and the newer Pro2. They share most of their codes, and each code page shows what the code means on each one. E01 acts differently on the two, and E15 and E16 mean different things, so go by the panel on your machine.

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.
