A few common error codes include: This blog post will introduce you to various error codes and give detailed instructions on how to repair yours should you encounter any of these issues.

Error Code E1

The E1 error code indicates that there is no voltage going to the thermostat at all. This could be caused by a faulty wall outlet, a tripped circuit breaker, or a faulty thermostat itself. If you’re seeing the E1 error code, we would recommend that you first check your circuit breaker and outlet to see if either of them is faulty. If not, then you’ll want to replace the thermostat. If you’re still experiencing issues after replacing the thermostat, then you should check your wiring. There may be an issue with your wiring that is preventing the thermostat from receiving power. If you find an issue with your wiring, make sure to have it fixed by a certified electrician.

Error Code E2

The E2 error code is caused by a thermostat malfunctioning due to a high level of voltage. This issue can either be caused by your water heater having higher than normal voltage or the thermostat itself having abnormal voltage. If your water heater has higher than normal voltage, we would recommend that you have your water heater replaced. If your thermostat has abnormal voltage, then you should replace it. This is because the E2 error code means that you will likely continue to experience issues with your thermostat.

Error Code E3

The E3 error code indicates that the thermostat cannot communicate with the water heater. This error code can occur if your wiring is faulty, there is loose wiring, or miscommunication within the system.

If the heating element has not tripped, then you may need to replace the thermostat. This is because the E8 error code means that you will likely continue to experience issues with your thermostat.

Error Code F1

The F1 error code means that the heating element is not receiving enough voltage from the thermostat. This error code can occur if the wiring is faulty, the thermostat is not set to “watts,” or the thermostat is broken. If your wiring has loose wiring, we would recommend that you have it fixed by a certified electrician. If the thermostat is not set to “watts,” then you should adjust it accordingly. If your thermostat is broken, then you will want to replace it. This is because the F1 error code means that you will likely continue to experience issues with your thermostat.

Error Code F2

The F2 error code means that the temperature of the water is too high. If you’re seeing the F2 error code, we would recommend that you check to see if the heating element has tripped. If the heating element has tripped, then you will need to reset the thermostat. If the heating element has not tripped, then you will want to replace the thermostat. If the heating element has not tripped, then you may need to replace the thermostat. This is because the F2 error code means that you will likely continue to experience issues with your thermostat.
