Kripsol pump display shows E10 and the pump stops; often coincides with very low or no water flow.

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

• 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: Open the Kripsol pump lid, remove the basket, and fill the pump housing completely with water using a hose. Reinstall the basket and lid, ensuring the lid O-ring is clean and lubricated with silicone grease. Restart the pump and watch for a solid flow.
• Inspect suction valves: Confirm that all necessary suction valves (skimmer, main drain) are open. Remove any obvious blockages from skimmer baskets and pump basket.
• Check for air leaks: While the pump is running, look for air bubbles in the pump lid and at the return jets. Tighten unions on the suction side and replace a flattened or cracked Kripsol pump lid O-ring.

If E10 continues despite good water level and no visible air leaks, the dry-run sensor or controller may be faulty and should be checked by a technician.
