AEG EF3

AEG error code EF3 indicates: AEG Lavamat / ProSteam 7000/8000/9000 Series: AquaControl anti-flood protection active EF3; float switch triggered in base pan with continuous safety drain..

The primary root cause for AEG code EF3 is: On AEG (AEG Lavamat / ProSteam 7000/8000/9000 Series) 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. Rotate selector to 12 o'clock (OFF), press and hold Start/Pause and Exit simultaneously for 4 seconds until the diagnostic LED sequence resets error memory.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if AEG code EF3 persists, the physical component causing On AEG (AEG Lavamat / ProSteam 7000/8000/9000 Series) 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.
