The E1 error indicates a temperature fault. The most common cause is that the unit was stored in a cold environment.
- Unplug the appliance.
- Let it sit at room temperature for at least 15 minutes to warm up.
- Plug it back in and try to use it again.
If that didn't work: If the E1 error persists after the warm-up period, the device is likely defective. Do not attempt to repair it yourself, as this will void the warranty.
Heads up: This appliance is designed for use at an ambient temperature between 5°C and 40°C. Always store it within this range to prevent the error from recurring.
