Common Eccotemp l10 problems

  • Poor water pressure: This is usually caused by a faulty pump or low voltage. Check your pump and make sure it is plugged in and receiving the correct voltage.
  • Bad thermostat or temperature sensor: The thermostat or temperature sensor inside the unit can sometimes malfunction. If the temperature is not consistent, replace the part.
  • Ignition failure: The Eccotemp L10 requires an external 12v power source to power the spark plug. If the spark does not ignite, check the power supply and make sure it is providing a strong current.
  • Leaking from the tank: If you notice water leaking from the tank, it may be caused by a faulty pressure relief valve or a broken O-ring. Replace the parts to stop the leak.
  • Corrosion and rust inside the tank: This is caused by hard water and can be prevented by using a water softener or a filter system.

Troubleshooting the Eccotemp L10

The Eccotemp L10 is a popular tankless water heater that is designed to provide an efficient and instant hot water solution for small homes or cabins. Unfortunately, like many other tankless water heaters, it can occasionally develop problems. Some of the most common Eccotemp L10 problems and their solutions are listed below.

Low Water Pressure

If the Eccotemp L10 is not providing enough hot water, it may be due to low water pressure. To fix the issue, check the inlet water pressure. The optimal water pressure range for the Eccotemp L10 is between 30-80 PSI, however, it will still work with slightly lower pressures. If the pressure is too low, you can install a pressure booster pump to increase it.

Poor Performance

The Eccotemp L10 may not be performing as efficiently as it should. This could be due to clogged or dirty filters, or a malfunctioning pressure relief valve. To fix this issue, try cleaning or replacing the filters and the pressure relief valve.

Temperature Fluctuations

If the Eccotemp L10 is experiencing temperature fluctuations, it could be due to a damaged thermistor. The thermistor is the component responsible for regulating the water temperature. Replacing it should fix the issue.


If the Eccotemp L10 is leaking, it could be due to a loose connection or a damaged gasket. To fix the issue, check all the connections and replace any damaged gaskets.
