Symptom / Description

FAULT

AEG Favorit / ProClean / ComfortLift Series: AquaControl flood protection active C3 (legacy DIVA alphanumeric); base float switch raised, continuous drain.

TELEMETRY // LIVESIG: FAULT_DETECTED

Root Cause

ROOT CAUSE

On AEG (AEG Favorit / ProClean / ComfortLift Series) models: Internal water leakage into bottom tray, loose hose clamp on sump or circulation pump, split tub bellow, or leaking dispenser gasket.

CIRCUIT // SUBSYSTEMLOGIC: ROOT_ISOLATED

Repair Instructions

UNLOCKED

1Unplug dishwasher and shut water tap. Mop up all water from bottom drip tray. Inspect hoses under pressure to locate and repair leak. 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.

1. Pre-Intervention Electrical Safety Protocols

!Electrical Safety Protocol: Isolate 230V mains power before accessing the lower pump housing.
!Prepare a shallow basin and absorption towels: expect 3 to 10 liters of stagnant trapped water upon filter opening.
!Beware of sharp foreign objects (broken glass, needles, screws) trapped inside the impeller cavity.

3. Preliminary Mechanical & Visual Checks

Unscrew coin trap filter and clear all foreign debris (coins, hairpins, bra underwires).
Rotate pump impeller manually: synchronous magnetic rotors should snap cleanly in 90° intervals without jamming.
Check drain hose for kinks, blockages, or unpunched sink spigots; verify drain height is between 65cm and 100cm.

Frequently Asked Questions: AEG C3

FAQ TREE

What does error code C3 mean on a AEG appliance?

AEG error code C3 indicates: AEG Favorit / ProClean / ComfortLift Series: AquaControl flood protection active C3 (legacy DIVA alphanumeric); base float switch raised, continuous drain..

What is the root cause of AEG error code C3?

The primary root cause for AEG code C3 is: On AEG (AEG Favorit / ProClean / ComfortLift Series) models: Internal water leakage into bottom tray, loose hose clamp on sump or circulation pump, split tub bellow, or leaking dispenser gasket..

How do I fix or resolve AEG error code C3?

To resolve error code C3: Unplug dishwasher and shut water tap. Mop up all water from bottom drip tray. Inspect hoses under pressure to locate and repair leak. 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.

Is it safe to clear AEG error code C3 by resetting power?

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if AEG code C3 persists, the physical component causing On AEG (AEG Favorit / ProClean / ComfortLift Series) models: Internal water leakage into bottom tray, loose hose clamp on sump or circulation pump, split tub bellow, or leaking dispenser gasket. must be inspected or replaced.

How do I test electrical resistance for AEG code C3 using a multimeter?

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..

What safety protocol must be followed before servicing AEG code C3?

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.
