If your AEG 8000 series washer/dryer pump is continuously running during a drying cycle, there could be several possible reasons for this behavior. Here are some common explanations:
Clogged Filter or Vent: The most common reason for the pump to run continuously during a drying cycle is a clogged filter or vent. A clogged filter or vent can restrict the airflow, causing the dryer to overheat. To prevent damage to the machine, the pump runs continuously to try and cool down the system.
Thermostat Issues: The dryer has a thermostat that regulates the temperature. If the thermostat malfunctions, it might not be able to sense the correct temperature, leading to the pump continuously running as a safety precaution.
Faulty Sensors: Modern washer/dryer combos often have multiple sensors to monitor various aspects of the drying process. If any of these sensors are faulty or sending incorrect signals, the machine may not be able to determine when to stop the pump.
Drainage Problems: If the machine is not draining water properly, it may trigger the pump to keep running. This could be due to a clogged drain hose or an issue with the drainage system.
Control Board Malfunction: The control board in the washer/dryer could be faulty, leading to incorrect commands being sent to the pump.
Ventilation System Issues: In some cases, the dryer may not be getting enough air circulation due to problems with the ventilation system or an obstructed air duct. This can cause the pump to run continuously.
To troubleshoot and identify the specific cause of the issue, it is recommended to:
Check the Filter and Vent: Make sure the filter and vent are clean and free from any blockages.
Inspect Sensors and Thermostat: If you are comfortable doing so, check the sensors and thermostat for any signs of damage or malfunctions.
Verify Drainage: Ensure that the drainage system is working correctly and there are no blockages in the drain hose.
Restart the Machine: Sometimes, electronic appliances can benefit from a simple restart. Turn off the washer/dryer, unplug it from the power source, wait for a few minutes, and then plug it back in.
If the issue persists despite these basic checks, it's best to contact AEG customer support or a qualified appliance repair technician to diagnose and fix the problem. Remember to refer to your washer/dryer's user manual for specific troubleshooting tips and safety guidelines.
