Potential Causes of the Problem
When your EcoSmart tankless water heater isn’t turning on, several factors might be at play. Below are some potential causes to investigate.
Electrical Issues
Electrical problems often inhibit the operation of your water heater. Check the following:
- Power Supply: Ensure the unit’s plugged in securely and the outlet is functional.
- Circuit Breaker: Confirm the circuit breaker hasn’t tripped. If it has, reset it and see if the heater powers on.
- GFCI Outlet: If you’re using a ground fault circuit interrupter (GFCI) outlet, test it for functionality by pressing the reset button.
