Candy AL02

Candy error code AL02 indicates: Candy Fresco / Krio / City Combi Total No-Frost Refrigerator: Water dispenser filter expiration / flow timeout alarm AL02; water purification filter cartridge life limit or fill slow rate detected..

The primary root cause for Candy code AL02 is: On Candy refrigeration units featuring Fresco Total No-Frost dual-circulation cooling, multi-sensor temperature regulation, and inverter compressor: 6-month cartridge timer elapsed, clogged carbon block filter, or low household water line pressure (<1.5 bar)..

To resolve error code AL02: Replace internal water filter cartridge. Flush 5 liters through dispenser to purge air. Press and hold Water Filter Reset button for 3 seconds. Reset: Press and hold Temp Set and Super Cool buttons together for 8 seconds until the display chime signals memory clear, then release.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Candy code AL02 persists, the physical component causing On Candy refrigeration units featuring Fresco Total No-Frost dual-circulation cooling, multi-sensor temperature regulation, and inverter compressor: 6-month cartridge timer elapsed, clogged carbon block filter, or low household water line pressure (<1.5 bar). must be inspected or replaced.

Set a digital multimeter to ohms (Ω). Disconnect power and test Compressor Motor Windings (Run/Start) & Defrost Heater across Across 3 compressor pins (Common, Run, Start): R(C-S) + R(C-R) = R(S-R). Winding to earth: >20MΩ (OL).. Expected nominal reading is 15Ω–25Ω (Run C-R), 20Ω–35Ω (Start C-S), 200Ω–400Ω (Defrost Heater). PTC Relay: 10Ω–30Ω at 25°C.. Tolerance: ±10%. Any low insulation resistance to casing (<2MΩ) trips the breaker. Defrost bimetal reads <0.5Ω when sub-zero..

Standard electrical safety protocol: 1. Disconnect 230V mains power before opening panels. 2. Verify zero voltage at test points. 3. Allow hot water or heating elements to cool below 30°C before handling.
