Is your Zanussi washing machine displaying an “E21” error message? Don’t worry, we’re here to guide you through what it means and how to fix it without immediately calling a technician.

What is E21 Error Code?

The E21 error code on Zanussi washing machines indicates an issue with water drainage. This could be due to an obstruction in the filter, drain pump, or pipes. It may also signify a failure in the drain pump or water level sensor.

Steps to Resolve E21 Error:

Reviewing the Filter and Drain Pump:

1. Disconnect the washer: Before doing anything, make sure the washer is unplugged from the power source.
2. Access the filter: Usually, the filter is located at the front bottom of the washer, behind a cover or panel.
3. Clean the filter: Remove it and clean it under the tap. Lint, coins, or even small socks can accumulate here.
4. Check the drain pump: If the filter is clean, the issue might be with the pump. It’s usually located near the filter, and you may need to disassemble it to check for blockages.

Inspecting Pipes and Connections:

1. Examine the drain hose: Ensure it’s not bent or crushed, which could impede water flow.
2. Check connections: Sometimes, water pump wires can come loose or get damaged. Look to make sure everything is in its place.

Water Level Sensor and Electronic Control:

1. Water level sensor: This sensor detects if the water has drained correctly. If it’s failing, it could be the cause of the E21 error.
2. Electronic controller: In less common cases, the issue might be with the washing machine’s electronic board.

What If It Still Doesn’t Work?

If the problem persists after following these steps, it could indicate intermittent failure of the drain pump or a more serious issue with the electronic control. In such cases, it might be necessary to contact a specialized technician.

Final Tips:

• Take it easy: If you’re unsure of what you’re doing, it’s better to pause and seek professional help.
• Replacement parts: If you need to replace any parts, ensure you get replacements compatible with your Zanussi washing machine model.
• Prevention: To avoid future blockages, check clothing pockets before washing and avoid overloading the machine.
