Diagnostics show E10; water dispenser or ice maker may not fill properly.

Safety first: Turn off the household water supply to the refrigerator and unplug the unit before disconnecting any water lines.

Steps to resolve:

• Check water supply: Confirm the shutoff valve is fully open and household water pressure is adequate (35–120 psi).
• Inspect external line: Look for kinks in the copper or plastic supply line behind the refrigerator.
• Replace water filter: A clogged filter can reduce flow and trigger errors. Install a genuine KitchenAid filter and flush 2–3 gallons of water.
• Check for frozen line: If the refrigerator is very cold, the water line in the door or freezer may freeze. Raise the freezer temperature slightly and leave doors closed for 24 hours.

If E10 persists and water flow is still poor, the water inlet valve or flow meter may need replacement. This involves disconnecting water lines and electrical connectors and is best done by a technician if you are not experienced.
