E20 on the Valley Select
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
Pressure reading is out of range, too high.
This shows up in the voltage window, flashing back and forth with the voltage reading, rather than as one of the diagnostics symbols. The machine may keep running while it shows. That does not mean the code can be ignored. Note the exact code and pass it along when calling for service.
Call a technician for this one, rather than opening the panel.

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.
