Error E21 in AEG washing machine

The E21 error in an AEG washing machine indicates a water drainage problem. This issue usually occurs due to an obstruction or malfunction within the drainage system.

Causes of Error E21

• Obstruction in the drain pump filter
• Stuck or damaged pump propeller
• Folded or obstructed drain hose connected to the pump
• Obstructed thick hose leaving the tub (Cuba)
• Electrical failure affecting the drain pump or wiring

How to Eliminate the E21 Error

Step 1: Safety First

Before starting any inspection or repair, disconnect the washing machine and unplug it from the power supply to avoid any risk of electric shock.

Step 2: Close the Water Intake

Turn off the water supply to prevent any water flow during the process.

Step 3: Check the Drain Pump Filter

Open the lid where the filter is located. Remove the filter plug and inspect its interior. If you find dirt, hair, or debris, clean it thoroughly with hot water and soap.

Step 4: Inspect the Pump Propeller

In the same area as the filter, check the pump propeller. Ensure it is not stuck or obstructed. Clean it with a brush if necessary to restore proper movement.

Step 5: Examine the Drain Hose

Tilt the washing machine backward carefully and inspect the hose connected to the drain pump. Make sure it is not folded, kinked, or obstructed. Straighten the hose if needed to allow free water flow.

Step 6: Check the Thick Hose from the Tub (Cuba)

Inspect the thick hose leaving the tub for any blockages or restrictions that could prevent proper drainage.

Step 7: Verify Electrical Components (If Needed)

If the error persists after checking physical obstructions:

• Use a voltmeter to verify that the drain pump is receiving power.
• If there is no voltage, the problem might be the electronic control module or wiring issues.
• If voltage is present, the drain pump itself may be faulty and require replacement.

Additional Tips

If after following all the above steps you have not been able to solve the E21 error code on your AEG washing machine, we recommend contacting technical service or a specialist. This ensures the problem is solved effectively and quickly, while avoiding potential damage to your washing machine.
