State water heaters have several reset paths depending on the unit type.
Electric units — ECO reset
Most common reset path:
- Turn off the breaker
- Remove the upper access panel
- Locate the red ECO button on the upper thermostat
- Press firmly until you feel/hear a click
- Replace panel and restore breaker
If the ECO trips again immediately, the underlying issue is active — typically a stuck-closed thermostat or shorted element.
Gas units — gas valve cycle
- Turn the gas control knob to "Off"
- Wait 5 minutes for any residual gas to dissipate
- Turn knob to "Pilot" (if standing pilot) or "On" (if electronic ignition)
- For standing pilot: depress pilot button and light per instructions on the unit
- Monitor LED flash code on gas valve
Power Vent — combined reset
Power vent units have an electrical reset (120V to fan) plus gas valve cycle:
- Unplug the 120V power to the fan
- Cycle the gas control knob (off → pilot → on)
- Plug power back in
- Fan should start within seconds when there's a heating call
Premier Hybrid heat pump — multiple reset paths
- Mode reset: press mode button on display panel
- ECO reset: red button on resistance backup thermostat (same as electric)
- Compressor lockout: turn off breaker for 30 minutes, restore. This clears compressor protection
- Factory reset: hold mode + temperature buttons for 10 seconds (requires re-pairing if Wi-Fi-equipped)
When reset doesn't fix things
Three consecutive resets with immediate re-trip = real fault. Stop cycling and work through the diagnostic walkthrough on the specific LED flash code or symptom.
Bottom line
Electric: ECO red button. Gas: gas valve cycle. Power Vent: power cycle + gas cycle. Premier Hybrid: mode reset → ECO → breaker → factory.
