Display shows E11 and the water dispenser or ice maker may not operate correctly.

Safety first: Unplug the refrigerator and shut off the household water supply before working on the water system.

Steps:

• Check water supply: Ensure the household shutoff valve is fully open and that the supply line to the refrigerator is not kinked.
• Replace water filter: A clogged filter can cause low flow and trigger errors. Replace the Etna refrigerator water filter if it is older than the recommended interval or visibly clogged.
• Access inlet valve: Remove the lower rear panel to locate the water inlet valve assembly. Inspect for leaks, cracks, or loose electrical connectors.
• Test valve coils: With power disconnected, remove the connectors and measure resistance across each coil. An open circuit indicates a failed coil.
• Check flow sensor (if present): Some Etna models include a flow meter in the water line. Ensure its connectors are secure and that there are no kinks before/after it.
• Replace faulty parts: Install a new Etna water inlet valve assembly or flow meter if defective. Use new seals and tighten fittings securely, but do not overtighten plastic threads.
• Restore water and power: Turn on the water supply, check for leaks, then plug in the refrigerator. Test dispenser and ice maker and confirm the E11 code clears.
