Sorry, I am an AI language model and I don't have the ability to create videos. However, I can provide you with some general troubleshooting steps to try and fix the E1 error on your water heater.

1. Check the Water Supply: Ensure that the water supply to your water heater is turned on and running smoothly. If there is any issue with the flow of water, then it can cause an E1 error code.

2. Check the Ventilation: Make sure that the ventilation system of your water heater is not blocked or clogged. Any obstruction in the ventilation system can lead to an E1 error code.

3. Check the Power Supply: Ensure that the power supply to your water heater is stable and consistent. Any fluctuations in the power supply can cause an E1 error code.

4. Check Temperature Sensor: The E1 error code can also indicate a problem with the temperature sensor. The temperature sensor is responsible for detecting the temperature of the water and signaling the heating element to turn on/off. If the temperature sensor is damaged, then you may need to replace it.

5. Contact the Manufacture: If you have tried all the above troubleshooting steps and are still facing the E1 error code, then it’s time to contact the manufacturer. They will be able to provide you with further instructions on how to resolve the issue.

Please note that these are general steps, and your specific water heater may have different troubleshooting steps. Therefore, it's always recommended to refer to the user manual or contact the manufacturer for guidance.
