AEG washing machine displays E23 and may not start or may stop mid-cycle with water inside

Safety first: Unplug the appliance and ensure the drum is manually drained via the pump filter before working on electrical parts.

• Inspect pump and wiring: Access the drain pump from the bottom or rear. Check the connector for burning, corrosion, or loose pins. Inspect the harness for chafing or cuts.
• Test pump resistance: With the pump disconnected, measure coil resistance using a multimeter. A dead short (very low ohms) or open circuit indicates a faulty pump.
• Check for signs of PCB damage: Remove the control board housing (usually at the top or rear). Look for burnt tracks or components near the pump control area.

If the pump tests faulty, replace the AEG drain pump. If the pump is good but E23 remains, the main control board likely requires professional repair or replacement.
