Pump displays E15 and fails to detect priming, shutting down after a short run.

Safety first: Turn off power before opening the pump lid or valves.

• Check water level: Ensure the pool water level is at least halfway up the skimmer opening so the skimmer does not draw air.
• Prime the pump: Close suction and return valves. Remove the Saci pump lid, fill the strainer housing completely with water, replace the lid, then open valves.
• Inspect for air leaks: Check the pump lid O-ring for cracks or dirt; clean and lubricate with silicone grease. Tighten unions on the suction side and inspect fittings for cracks.
• Clear suction line: Remove the skimmer basket and any suction-side cleaners. Use a hose or plumbing snake to clear obstructions if flow is restricted.

After correcting issues, restart the pump and observe for a solid water flow. If E15 persists, the dry-run sensor or control logic may be faulty.
