Display shows E10; machine reports a water circuit error and refuses to start brewing.

Safety: Unplug the appliance before any internal inspection. Hot water and steam can cause burns.

User-level actions:

• 1. Remove water filter: If your Electrolux model uses a tank filter cartridge, remove it and try operating without it. A clogged filter can trigger E10.
• 2. Full descaling: Run at least one complete descaling cycle with Electrolux-approved descaler. If the error persists, repeat once more.
• 3. Check tank seating and level: Ensure the tank is fully inserted and filled above the minimum mark.

Advanced actions:

• 4. Inspect internal tubing: Open the housing and check all silicone hoses for blockages, kinks, or collapsed sections. Replace any suspect hoses.
• 5. Verify sensors: Depending on model, check the water level sensor (float or conductivity type) and flowmeter for proper connection and cleanliness.

Resolution: If E10 remains after descaling and hose inspection, a sensor or control board fault is likely and should be diagnosed by a professional.
