Zanussi C2

Zanussi error code C2 indicates: Zanussi Aquacycle / ZDF Series / AirDry Dishwasher: Water drainage timeout alarm C2 (legacy DIVA alphanumeric); tub fails to drain water before next cycle step..

The primary root cause for Zanussi code C2 is: On Zanussi (Zanussi Aquacycle / ZDF Series / AirDry 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/Pause plus Skip/Option button simultaneously for 5 seconds until three rapid confirmation beeps clear persistent error memory.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Zanussi code C2 persists, the physical component causing On Zanussi (Zanussi Aquacycle / ZDF Series / AirDry 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.
