Water filter or water system alarm; display shows AL05 or filter icon, possibly accompanied by reduced water flow.

Safety first: Close the household water supply valve to the refrigerator before removing the filter or working on water lines. Keep towels handy for spills.

Step 1 – Replace the water filter:

• Locate the Fhiaba water filter (often inside the refrigerator compartment or grille area).
• Turn or release the filter according to the arrow direction and pull it out.
• Install a genuine Fhiaba-compatible replacement filter, ensuring it locks fully into place.
• Turn the water supply back on and run several liters of water through the dispenser (if equipped) to purge air and carbon fines.

Step 2 – Check water supply line:

• Inspect the external water line for kinks or sharp bends behind the refrigerator.
• Verify the shutoff valve at the wall is fully open.

Step 3 – Reset the alarm:

• Use the control panel to reset the filter or water alarm (refer to the user manual; usually by holding the filter or alarm button for several seconds).
• If AL05 persists and water flow is still poor, the inlet valve or internal lines may be restricted.

Step 4 – Inlet valve check (advanced):

• Unplug the refrigerator and access the rear lower panel to reach the water inlet valve assembly.
• Inspect for leaks or mineral buildup at the valve outlets.
• A technician can test coil resistance and voltage during a call for water; replace the valve if defective.
