An E3 code means the cooling element is overheating. Usually that's because air can't move around the machine freely, though occasionally it points to a fan problem.
First, check the fans
With the machine plugged in and cooling, listen at the back. You should hear the fans running, though how loud they are varies with the room temperature and how hard the machine is working, so quiet is normal.
If you can't hear anything at all while the machine is cooling, the fan may have failed. That isn't something you can fix at home, so get in touch and we'll take it from there.
If the fans are running, work through the rest below.
Clear the airflow
1. Clear the vents.
Unplug your machine, then lift dust away from the vent at the back with a vacuum or a soft brush.
2. Give it room to breathe.
Leave at least 10 cm of clear space in all directions, especially at the back. Check nothing is pushed up against it.
3. Move it away from heat.
Keep your machine out of direct sunlight and away from heat sources. That includes ovens and radiators, but also other appliances such as fridges, freezers and dishwashers, which give off more heat than people expect.
Once the airflow is clear, give your machine a few hours to cool down and recover before you expect it back to normal.
In warm weather
We see more E3 codes during hot spells, and it usually isn't a fault. Your machine can handle room temperatures up to 38°C, but only with air moving freely around it. During a heatwave:
- Move it to the coolest room you have, even temporarily.
- Give it more space than usual, particularly at the back.
- Close curtains or blinds during the hottest part of the day.
- Keep the rear vents clear, as they matter more when it's warm.
Still showing E3?
If the code is still there after clearing the vents and giving your machine time to recover, get in touch. Let us know whether you can hear the fans running, where your machine is standing, and what's nearby.
