Symptom / Description

FAULT

AEG Favorit / ProClean / ComfortLift Series: Drain pump triac failure or feedback sensing mismatch i23 on main electronic motherboard.

TELEMETRY // LIVESIG: FAULT_DETECTED

Root Cause

ROOT CAUSE

On AEG (AEG Favorit / ProClean / ComfortLift Series) models: Triac destroyed by short-circuited drain pump stator coil, moisture on pump spade terminals, or open sensing resistor on motherboard.

CIRCUIT // SUBSYSTEMLOGIC: ROOT_ISOLATED

Repair Instructions

UNLOCKED
1Measure drain pump coil resistance (must be 160–220 Ω; if < 150 Ω replace pump first!). Inspect PCB for burned triac package. 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 I23

FAQ TREE
What does error code I23 mean on a AEG appliance?

AEG error code I23 indicates: AEG Favorit / ProClean / ComfortLift Series: Drain pump triac failure or feedback sensing mismatch i23 on main electronic motherboard..

What is the root cause of AEG error code I23?

The primary root cause for AEG code I23 is: On AEG (AEG Favorit / ProClean / ComfortLift Series) models: Triac destroyed by short-circuited drain pump stator coil, moisture on pump spade terminals, or open sensing resistor on motherboard..

How do I fix or resolve AEG error code I23?

To resolve error code I23: Measure drain pump coil resistance (must be 160–220 Ω; if < 150 Ω replace pump first!). Inspect PCB for burned triac package. 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 I23 by resetting power?

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if AEG code I23 persists, the physical component causing On AEG (AEG Favorit / ProClean / ComfortLift Series) models: Triac destroyed by short-circuited drain pump stator coil, moisture on pump spade terminals, or open sensing resistor on motherboard. must be inspected or replaced.

How do I test electrical resistance for AEG code I23 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 I23?

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.
