AEG heat pump dryers are known for their energy efficiency and gentle fabric care, but like all appliances, they require regular maintenance to perform at their best. Proper upkeep not only extends the lifespan of your dryer but also prevents common issues such as long drying times, error codes, or even breakdowns. In this guide, we’ll walk you through essential maintenance tips for your AEG heat pump dryer, including cleaning the filters and condenser, checking the moisture sensors, and troubleshooting problems. For a broader overview of AEG appliance care in Spain, see our complete guide to AEG appliance repair in Spain.
Why Regular Maintenance Matters for Heat Pump Dryers
Unlike traditional vented or condenser dryers, heat pump dryers recycle hot air to dry clothes, making them more energy-efficient. However, this closed-loop system relies on clean components to maintain airflow and heat exchange. Over time, lint, dust, and detergent residue can accumulate, reducing efficiency and potentially causing the dryer to overheat or stop working. Regular maintenance can prevent these issues and save you money on energy bills. In Spain, where electricity prices average around €0.15–€0.20 per kWh, an inefficient dryer can add significant costs. By keeping your AEG dryer clean, you can maintain its A+++ energy rating and avoid unnecessary repairs.
Cleaning the Lint Filter
The lint filter is the most frequently accessed component in any dryer. In AEG heat pump dryers, the filter is typically located inside the door or at the bottom of the opening. Cleaning it after every drying cycle is essential for maintaining airflow and preventing fire hazards.
How to Clean the Lint Filter
- Open the dryer door and locate the lint filter. It is usually a mesh screen that slides out.
- Remove the filter and gently wipe off lint with your hand or a soft brush. Do not use water unless the filter is heavily clogged; if you do, ensure it is completely dry before reinserting.
- For a thorough clean, wash the filter with warm water and a mild detergent every month. Allow it to dry completely before placing it back.
- Inspect the filter for damage. If it is torn or warped, replace it with an original AEG part (available at retailers like MediaMarkt or El Corte Inglés for about €15–€25).
Neglecting the lint filter can lead to longer drying times and trigger error codes such as E20 or E21. For more on error codes, check our article on AEG dryer error codes.
Cleaning the Condenser Unit
Heat pump dryers use a condenser to cool and dehumidify the air. Over time, lint and fluff can accumulate on the condenser fins, reducing efficiency. AEG recommends cleaning the condenser every 6–12 months, depending on usage.
Step-by-Step Condenser Cleaning
- Unplug the dryer or switch off the circuit breaker for safety.
- Open the condenser access door, usually located at the bottom front of the machine. On some models, it may be behind a flap behind the door.
- Remove the condenser unit by pulling it out. It may be secured with clips or a locking mechanism.
- Rinse the condenser under running water from the back (the side with the fins) to flush out lint. Do not use brushes or sharp objects, as they can damage the fins.
- If the condenser is very dirty, soak it in warm water with a mild detergent for 30 minutes, then rinse thoroughly.
- Allow the condenser to dry completely before reinserting. Ensure it is seated correctly and the door is closed securely.
A dirty condenser is a common cause of the dryer not heating properly. If you experience this issue, refer to our guide on AEG dryer not heating.
Checking and Cleaning the Moisture Sensors
AEG heat pump dryers use moisture sensors to detect when clothes are dry. These sensors are located inside the drum, usually on the front or rear wall. Limescale, detergent residue, or fabric softener can coat the sensors, causing them to misread moisture levels and stop the cycle prematurely or continue drying unnecessarily.
How to Clean Moisture Sensors
- Locate the moisture sensors: they are typically two metal strips about 5 cm long near the lint filter housing or inside the drum.
- Clean the sensors with a soft cloth and a mixture of water and vinegar (1:1 ratio) or a specialized sensor cleaner. Do not use abrasive pads or harsh chemicals.
- Wipe gently to remove any residue. For stubborn deposits, use a non-abrasive sponge.
- Perform this cleaning every 3–6 months, or more often if you use fabric softener frequently.
Faulty sensors can also trigger error codes. For a complete list, see our AEG dryer error codes article.
Inspecting and Cleaning the Heat Exchanger
The heat exchanger is a critical component that transfers heat from the refrigerant to the air. It is located behind the condenser and is less accessible. While it does not require frequent cleaning, it should be inspected annually.
Cleaning the Heat Exchanger
Accessing the heat exchanger requires removing the condenser unit first. Once the condenser is out, you may see the heat exchanger fins. Use a soft brush or a vacuum cleaner with a brush attachment to gently remove dust and lint. Be careful not to bend the fins. If the heat exchanger is heavily soiled, it may need professional cleaning. In Spain, authorized AEG service centers charge around €80–€120 for a full maintenance service that includes heat exchanger cleaning.

Cleaning the Door Seal and Drum
The door seal and drum can accumulate lint, hair, and debris, which can affect drying performance and cause odors. Clean them regularly to maintain hygiene.
Cleaning Steps
- Wipe the door seal with a damp cloth after each use to remove lint. Pay attention to the folds where debris can hide.
- Every month, clean the drum with a damp cloth and a mild detergent. For stubborn stains, use a non-abrasive cleaner.
- Run an empty cycle with a dryer cleaning product (available at supermarkets like Carrefour or online at Amazon.es for about €5–€10) to remove residue and odors.
Maintaining the Heat Pump System
The heat pump itself is a sealed unit and requires no user maintenance. However, the filters and condenser protect it from lint. If the heat pump fails, it is a costly repair. To avoid this, ensure that the condenser and filters are always clean. Also, check the drain hose for blockages if your dryer has a condensate drain option.
Drain Hose Maintenance
- If your dryer is connected to a drain, inspect the hose for kinks or blockages every few months.
- Disconnect the hose and flush it with water if necessary.
- Ensure the drain outlet is not clogged with lint.
Troubleshooting Common Issues
Even with regular maintenance, you may encounter problems. Here are some common issues and solutions.
Long Drying Times
If your dryer takes longer than usual, check the lint filter, condenser, and moisture sensors. Also, ensure the load is not too large or too small. Overloading reduces airflow, while underloading confuses sensors.
Error Codes
AEG dryers display error codes like E20 (blocked filter) or E21 (condenser issue). Refer to our AEG dryer error codes article for a full list and solutions.
Dryer Not Heating
If the dryer runs but does not heat, the heat pump or heating element may be faulty. First, check the condenser and filters. If they are clean, the issue may be electrical. See our AEG dryer not heating guide for more.
Unusual Noises
Noises can be caused by loose objects in the drum, worn drum bearings, or a failing fan. Check for foreign objects and ensure the dryer is level. If the noise persists, contact a professional.
Professional Maintenance and Service
While many maintenance tasks can be done at home, some require professional expertise. In Spain, authorized AEG service centers can perform annual maintenance including condenser and heat exchanger deep cleaning, refrigerant checks, and electrical inspections. Prices typically range from €80 to €150. If your dryer is still under warranty, schedule a service with an authorized technician to avoid voiding the warranty.
For DIY repairs, always unplug the dryer first. If you are unsure, consult our complete guide to AEG appliance repair in Spain for advice on finding reliable technicians.
