Do you remember where you threw your Electrolux dryer user manual? It can be frustrating when you don’t have it around because your machine may display errors you cannot decipher.

Common Electrolux dryer codes—E64, E65, E66, EF1, and E91— may indicate a problem with the heating element, restricted airflow, damage to the control board, vent issue, or malfunction of electronic parts. While you can fix some of these issues, others might need a qualified appliance technician.
If you see any of these codes, it’s important to take note of the problem and take steps to fix it. Otherwise, your dryer may not operate correctly or stop working altogether. In this post, I’ll explain what the error codes mean so that you can troubleshoot your dryer yourself.
How To Fix Electrolux Dryer Codes (E64, E65, E66, Ef1, E91)
Here are some of the most common error codes you may see on your Electrolux dryer, along with the most likely cause and how to fix it.

Error Code E64
Error Code E64 shows up when there’s a problem with the heating element of your Electrolux dryer. You should check the wires connecting to the heater as well as the heater itself.
How to Fix
The most likely scenario in this situation is that you’ll need to replace the heating element. If you’re uncomfortable handling these sorts of components, I strongly recommend asking for professional assistance since this will save you money down the line.
The following YouTube video will show you how to fix an error code E64 on Electrolux dryers:
Error Code E65
This error means the dryer isn’t getting enough airflow. In simple terms, it means that the high-temperature thermostat has been tripped more than once. This is likely because the dryer’s blower has collapsed or broken. When this occurs, your dryer won’t dry your clothes properly.
How to Fix
To fix the problem, you’ll need to clean the dryer’s manifold. Follow the steps below:
- Unplug your dryer.
- Locate the hot air manifold at the back of your dryer. You will see a round connection at the bottom of the manifold.
- Detach the hot air distribution manifold.
- Clean the manifold and around the blower.
- Rotate the blower wheel by hand to ensure it is not obstructed.
- Reassemble the manifold.
- Screw it back into place and plug your dryer back in.
If you’re having trouble with this process, call a professional to help. If the error code persists after troubleshooting, have a professional examine the pressure distribution manifold. There could be other problems with it that a simple cleaning can’t fix.
Error Code E66
Error Code E66 typically pops up when the dryer vents are clogged, causing the dryer to overheat. It’s also possible that the control board is damaged due to electrical faults in any of the dryer’s components. In this case, you can perform this yourself, but it’s best to call a technician to ensure it’s done properly.

How to Fix
Assuming there are no other issues (like any serious damage to the dryer or its components as a result of overheating), you can typically fix the problem by unclogging the vents.

Error Code EF1
If your Electrolux displays error code EF1, it indicates that you have a problem with the ventilation system. Usually, this means that you need to unclog the vents by removing any blockages. Another possible cause would be a faulty thermistor.
Your dryer is equipped with a thermistor sensor that monitors the dryer temperatures and communicates to the dryer if there’s a clog in the vents. If your vents look fine and there are no blockages, you might have a thermistor issue.
How to Fix
If you think your dryer is experiencing a thermistor issue, you’ll need to replace it:
- Locate the thermistor, usually mounted on the blower wheel below the load drum.
- Remove this component and replace it with a new thermistor sensor.
To replace your sensor, you’ll need to contact your manufacturer to get the correct component.
Error Code E91
This error is a typical malfunction of the electronic parts of the Electrolux dryer. The error shows a lack of communication between the user interface and the main control board.

How to Fix
Electrolux advises that when you face this error, you should power cycle the machine. Here are the steps to do this:
- Turn off and unplug the dryer.
- Leave it switched off for about 5 mins.
- Turn the appliance back on and see if everything is fixed.
If this fix doesn’t work, you are advised to call Electrolux technicians for further assistance and repairs.
Usually, if there is an issue with your machine affecting its electrical system, then you are advised to seek professional repair services. Trying the repair by yourself and then ending up breaking even more components may lead to losing your warranty.

Electrolux Clothes Dryer Care Guide
Cleaning and general care for your dryer can significantly reduce damage to your Electrolux dryer. Sometimes the little things result in various errors, which sometimes become costly to repair if left unattended.
Here are a few tips for caring for your Electrolux clothes dryer:
- Regularly clean the lint filter. Lint buildup causes a blockage that restricts airflow, so your dryer won’t be able to dry your clothes properly or may take a long time to do so.
- Do not use the dryer without the lint filter.
- Don’t use spray cleaners when cleaning your Electrolux dryer. Instead, use household cleaners you can apply to a cloth to control the process.
- Have a technician check your dryer and perform a thorough clean every 18 months.
