E14 error; water dispenser not dispensing or very slow; ice maker may not fill.

Safety first: Unplug the refrigerator and close the household water supply valve before disconnecting any water lines.

Steps:

• 1. Check water supply: Ensure the household shut-off valve is fully open and that water pressure is adequate. Test by disconnecting the line at the refrigerator and briefly opening the valve into a bucket.
• 2. Inspect inlet valve: The Siemens water inlet valve is usually located at the rear bottom. Remove the rear cover and inspect for leaks or damage.
• 3. Clean inlet screens: Turn off water, disconnect the inlet hose, and check the small mesh filter in the valve. Clean any debris with a soft brush.
• 4. Test valve coils: With the unit unplugged, measure resistance of the valve solenoids. An open coil indicates a failed valve that must be replaced.
• 5. Check for frozen lines: On models with water in the door, a frozen line in the door can trigger E14. Increase refrigerator temperature slightly and leave door closed for several hours to thaw, or use manufacturer-approved thawing methods.
• 6. Replace valve or flow sensor: If the valve or flow meter is defective, install the correct Siemens replacement part and check for leaks after reassembly.

Warning: Always check for leaks after working on water connections. Use new sealing washers where required.
