The display shows E18 and the pump stops; this may coincide with very low system pressure.

Safety first: Turn off power before opening baskets or unions.

• Clean baskets: Empty the skimmer and AquaJet pump strainer baskets of leaves and debris.
• Check water level: Ensure the pool water level is at least halfway up the skimmer opening to prevent air ingestion.
• Inspect suction plumbing: Tighten the suction union at the pump and check for cracks in fittings. Replace any damaged parts.
• Prime and restart: Fill the pump housing with water, reseal the lid, and restart. If E18 persists, have the suction line checked for underground leaks or blockages.
