If you are having issues with your Hitachi product or if you encounter errors while using your home appliances, then you might encounter error code E1 on your device’s screen. This error can occur when there is an issue with your device or it can occur when there is an issue with your power supply.
Sometimes, common device errors or server problems can also cause this error.
To fix this error, you need to try a few solutions.
- Replace the fan motor
- Check for high or low pressure
- Restart the unit operation
- Replace any faulty temperature sensor
- Change the filter
One possible solution is to replace the fan motor of your AC. If you find that the fan motor is not working properly, then you can purchase a new one from a local hardware store. This can be done in a few minutes and it will not cost you much.
If your AC has low or high pressure, then you need to check the pressure gauge on your device. If it is out of range, then you need to replace the pressure gauge with a new one. The cost of this replacement will depend on the size of your AC unit.
Another possible solution is to restart your AC unit’s operation. You must do this before checking for any other issues because it might fix any errors that might be present on your device. To restart your AC unit, press and hold the power button for 10 seconds until the LED light comes on again.
This should solve any problems that might be present on your device.
Another possible solution is to replace any faulty temperature sensor of your device with a new one if they are not working properly or if it is faulty as well. If there are too many faulty temperature sensors, then this might cause errors in your device’s operation and it might even damage them over time as well.
Changing the filter can also be a solution to this error. You must remove the filter from your AC unit and clean it. If there are too many dust particles in the filter, then it might cause this error to occur.
The last possible solution is to replace the entire AC unit with a new one if you are having issues with your device or if it is faulty as well. Contact your customer support and try to negotiate for a new AC unit, especially if your product is still under guarantee.
