EcoSmart Water Heater Problems [7 Easy Solutions]

You may encounter the following problems while using the EcoSmart water heater. The issues and solutions are the following:  

1. Thermistor’s Problem

Two thermistors consist of each EcoSmart water heater. One thermistor is in red wire (outlet side), and another is in yellow wire (inlet side). If there is any problem with the thermistor’s function, your water heater will not produce hot water. The probable reasons for this problem are:

  • The LED display not working or showing the set temperature
  • The thermistors control board failed to send power to the water heaters elements
  • Disconnected thermistors

Solution

Even if there are some problems with thermistors, the EcoSmart water heater can still run and remain activated. To solve the thermistors problem, do the following:

  • Ensure thermistors unit power by turning on the breaker to “ON” position
  • Make sure the LED display is showing the set temperature
  • Replace the disconnected parts of the thermistors

2. Flow Meter Problem

The EcoSmart water heater’s inlet side consists of the flow meter. Flow meter is important as it activates the heater. But for the following reasons, there may be some issues in the EcoSmart heater’s flow meter. The reasons are:

  • LED display fail to illuminate
  • Hindrance in free spinning
  • Blockage or clog in the flow meter
  • Blockage in the propeller

Solution

If your EcoSmart water heater won’t start or stop running because of a flow meter fault, you should do the following:

  • Run the water in high volume to clean the flow meter
  • Call an expert and check whether the meter is sensing the water flow or not
  • Flash out the propeller blocking particles
  • Have the water flowing at a high volume to match the illumination of the water display

3. Displays an Error Code “E1.”

Error code “E1” on the EcoSmart water heater display indicates that the inlet thermistor of the heater fails to read correctly. It also shows that you may need to replace the temperature. The reasons for this problem are the following:  

  • LED display turn off
  • The improper placing of the round knob
  • LED display fails to read CE1
  • Hinders smooth running of water

Solution

Try out the following solutions which can resolve the issue temporarily. The solutions are:

  • Turn on the LED display and keep it running
  • Turn on water so that the LED display can read the error
  • For 3-5 seconds, press the round knob, and after that release it
  • Run the water for 3-4 minutes and check the heater for hot water

4. High Flow Rate of Water

EcoSmart water heater’s other problem is the high flow rate, indicating error code “E5”. The reasons behind this problem are:

  • Too high-water flow
  • Water valve’s outgoing or incoming is highly tight
  • The round knob fails to rotate clockwise

Solution

The aerator is the mandatory equipment in the water heater to control the too high water volume. However, the following solutions can also help you to solve the problem.

  • Use aerator in shower, sink, or tub to control or lower the water volume
  • Slow down the incoming or outgoing water coming from the water valve or passing through the system
  • Install a slightly close flow restrictor to control the water flow
  • Make sure the clockwise rotation of the round knob

5. Cold Water

Your EcoSmart water heater won’t provide hot water if the thermostat fails to receive proper power. Other reasons for this problem are the following:

  • Faulty thermostat
  • Lack of power
  • Faulty heating element
  • Faulty circuit breaker

Solution

Don’t worry if your water heater starts to supply the cold water in your home. You can solve the cold-water problem by doing the following:

  • Make sure the heater’s thermostat is receiving power
  • Check the power switches and make sure it is supplying proper power to the heater
  • Replace and reset tripped circuit breaker
  • Make certain the power indicators of the buttons are on

6. Leaks in Water Heater

The following reasons are responsible for the leak in your EcoSmart water heater. The reasons are:

  • Loose or over-tightening plumbing connections
  • Loose heating elements
  • Faulty gasket

Be a little careful, and you can prevent the water heater from leaking problems. The solution for this problem is:

  • Check the loose connections and tighten them to stop the leak
