E-1 Error code | Inlet Thermistor
If you unit is displaying an E1 error code. Your unit is notifying you the inlet thermistor is not
reading correct Temperature and may need to be replaced. In order to temporary resolve this
issue please follow the below steps. Keep in mind, this is only a short term fix. You will still be
responsible for replacing you inlet thermistor.
Bypassing E1 Error Code
1. Turn on water so LED display is on and reading E1 error
2. Hold down round knob for 3/5 seconds and release.
3. At this point your LED display should be reading CE1
4. Keep water running for 2/3 mins and check for hot water.
This work around will allow you to receive hot water while waiting for the replacement part.
While your unit is running in the CE1 mode, the heat will default to 125 degrees as a normal tank
heater would. In this mode you will not be able to control your outlet temperature. Keep in mind
you may need to mix some cold water in order to reach the desired Temperature.
If the heater is still within warranty, part will be covered. If not, parts can be purchased
online at Amazon.com or through our support team see links below.
