Can I fix Pentair code Priming Failure myself?

Start with these safe checks: Turn the pump off at the breaker, fill the strainer pot with water, and check that the lid O-ring is clean and seated. Make sure the pool water is mid-skimmer and suction valves are open. If it still won't prime, a pool pro should check for suction-side air leaks.

When should I call a technician for code Priming Failure?

If it still won't prime, a pool pro should check for suction-side air leaks. Water and electricity together can kill. Turn the equipment off at the breaker before you open anything, never touch equipment while standing in water, and stay out of the pool or spa if you feel tingling or suspect an electrical problem. Leave wiring, boards and GFCI faults to a licensed electrician or service tech.
