Castor C2

Castor error code C2 indicates: Castor CDF Series / Lavastoviglie Silenziosa Dishwasher: Water drainage timeout alarm C2 (legacy DIVA alphanumeric); tub fails to drain water before next cycle step..

The primary root cause for Castor code C2 is: On Castor (Castor CDF Series / Lavastoviglie Silenziosa Dishwasher) models: Drain filter clogged by food residue, pump impeller jammed with broken glass, kinked drain hose, or drain pump motor open (160–220 Ω)..

To resolve error code C2: Remove sump filter assembly and clean thoroughly. Check that pump impeller rotates freely. Measure pump resistance (160–220 Ω). Hold Start and Reset keys for 5 seconds until the display clears the alarm code and restores standby status.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Castor code C2 persists, the physical component causing On Castor (Castor CDF Series / Lavastoviglie Silenziosa Dishwasher) models: Drain filter clogged by food residue, pump impeller jammed with broken glass, kinked drain hose, or drain pump motor open (160–220 Ω). must be inspected or replaced.

Set a digital multimeter to ohms (Ω). Disconnect power and test Drain Pump Motor Stator Coils across Across pump motor spade terminals (L-N unclipped). Expected nominal reading is 160Ω–220Ω (Sync 230V) / 20Ω–45Ω (3-Phase BLDC). Tolerance: ±10% balance. Insulation resistance between coil and motor chassis must exceed 20MΩ..

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.
