Error Code AL1

Error Code AL1 in Your Dishwasher (AEG, Electrolux, Quelle-Privileg)

Has your dishwasher displayed error code AL1? This indicates a serious heating system fault detected by the appliance’s control unit. Error code AL1 specifically signals a problem with the appliance’s ability to accurately monitor or control water temperature.

Understanding the Cause of AL1

Error code AL1 typically points to one of two related issues:

1. Temperature Sensor (NTC) Short Circuit: The NTC (Negative Temperature Coefficient) sensor is responsible for measuring the water temperature inside the dishwasher tub. A short circuit means the sensor is sending an incorrect or constant signal to the control board, usually indicating an extremely high temperature, regardless of the actual water heat.
2. Over-Temperature Safety Trigger: The error message will also be triggered as a safety measure if the water temperature inside the appliance exceeds 85°C (185°F). This indicates a critical failure in the heating circuit or the temperature regulation system, leading to uncontrolled heating. The dishwasher stops operating immediately to prevent damage to internal plastic components or potential hazards.

What to do:

• Turn off the dishwasher immediately. This is the most crucial initial step. To prevent further electrical damage or the risk of uncontrolled heating, you must completely cut the power supply to the unit. Do not just press the power button; unplug the appliance from the wall socket, or switch off the dedicated circuit breaker supplying power to the dishwasher. Preventing continued operation mitigates the risk associated with a short-circuited electrical component.
• Contact an authorized service technician. Diagnosing and resolving a short circuit involving the temperature sensor (NTC) or the associated wiring requires specialized knowledge and tools for electrical testing. A short circuit indicates a fundamental electrical failure within the unit. Attempting to repair this yourself can be dangerous due to accessing high-voltage components and may result in further irreparable damage to the control board, potentially voiding any remaining manufacturer or retailer warranty. Only use technicians officially authorized by AEG, Electrolux, or your dealer.
• Mention error code AL1 when you contact them. Providing the specific code allows the technician to immediately narrow down the potential component failures (NTC sensor, wiring harness, or related control board relays) and ensure they bring the necessary replacement parts or diagnostic tools, leading to a faster and more efficient repair appointment.
