Tankless Water Heater Error Codes
If you have a tankless water heater, you may occasionally see an error code displayed on the unit. These codes can be confusing, but they usually indicate a simple problem that can be easily fixed. In this blog post, we’ll decode some of the most common error codes and tell you what you can do to fix them.
Error Code E1: This code indicates that there is insufficient water flow to the unit. The first thing you should check is the water pressure coming into your home. If it’s too low, the unit won’t work properly.
You may need to adjust your home’s water pressure regulator or install a new one if yours is not working properly.
Error Code E2: This code means that the temperature of the incoming water is too low. The minimum temperature for most tankless units is around 55 degrees Fahrenheit.
If your water heater is in a cold basement or garage, it may not reach this temperature unless you use a recirculating pump to bring warmer water from elsewhere in your home.
Error Code E3: This code indicates that the temperature of the outgoing hot water is too high. This could be due to a faulty thermostat or an obstruction in the exhaust vent pipe.
Check both of these things and make sure they are clear before resetting the unit again.
Error Code E4: This code signals that there is a problem with ignition or flame detection. First, check for any debris around the burner assembly and clean it off if necessary.

2. The unit may be plugged into an outlet that does not provide enough power.
Try plugging the unit into a different outlet.
3. The inlet water pressure may be too low. Check the pressure and adjust it accordingly.
4. There may be something blocking the inlet or outlet of the unit. Remove any obstructions and try again.
