2. Inspect Power Supply:
   Plug the unit into a functioning outlet. Use the multimeter to verify that the correct voltage is reaching the heater.
3. Examine Temperature Settings:
   Review the temperature settings. Ensure they don’t exceed the manufacturer’s recommended level.
4. Assess for Faulty Sensors:
   Locate the temperature sensor and connections. Check for any visible damage that could impair functionality.
5. Monitor Water Pressure:
   Measure the incoming water pressure with a gauge. Confirm that it meets the specified range in the owner’s manual.
6. Consult the Error Codes:
   Refer to your owner’s manual for any additional error codes that might provide insight into the E2 error.

By following these steps, you can identify the root cause of the E2 error code and take appropriate actions to resolve it.

Solutions to Fix Error Code E2

Error code E2 may hinder your hot water supply but it’s possible to resolve it with a few straightforward solutions. Here’s how to tackle the issues:

Quick Fixes and Troubleshooting

• Check Water Flow: Ensure the water flow isn’t restricted. Inspect the inlet filter for debris. Clean it if necessary to restore proper water flow.
• Inspect Power Supply: Confirm the unit receives adequate power. Check for tripped breakers or blown fuses. If the power supply is inadequate, reset or replace the necessary components.
• Examine Temperature Settings: Review your temperature settings. You should set them between 120°F and 140°F for optimal performance. Adjust the settings if they exceed this range.
• Test Sensors: Faulty sensors can trigger the E2 error. Use a multimeter to test the temperature sensor’s resistance. Replace it if the readings are outside the manufacturer’s specifications.
• Monitor Water Pressure: Low water pressure can lead to error E2. Utilize a water pressure gauge to assess the flow. If pressure is below 30 PSI, troubleshoot your plumbing system.
