Castor EF3

Castor error code EF3 indicates: Castor CWF Series / Master Lavatrice Front Load Washer: AquaControl anti-flood protection active EF3; float switch triggered in base pan with continuous safety drain..

The primary root cause for Castor code EF3 is: On Castor (Castor CWF Series / Master Lavatrice Front Load Washer) models: Water leak from tub hose, split door bellow gasket, leaking water inlet valve, or drain pump housing crack accumulating water in base..

To resolve error code EF3: Disconnect power and shut water tap. Tilt machine backward 45° to drain base tray onto towels. Locate leak source and replace leaking component. 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 EF3 persists, the physical component causing On Castor (Castor CWF Series / Master Lavatrice Front Load Washer) models: Water leak from tub hose, split door bellow gasket, leaking water inlet valve, or drain pump housing crack accumulating water in base. 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.
