Why Is My Water Heater Not Heating Up Despite Resetting the Button?

A reset that doesn’t restore hot water usually points to a failed thermostat, burned-out heating element (electric), bad thermocouple/igniter (gas), tripped breaker, or heavy sediment buildup. It can also be a closed gas valve, extinguished pilot, faulty mixing valve, or a tankless flow/error issue. G&C offers same-day water heater repair for many Franklin homeowners and can often dispatch in 1–3 hours in emergencies.

Quick checks:

• Verify breaker is on (electric) or gas valve and pilot/igniter (gas).
• Listen for burner/element activity.
• Run hot at one faucet only; test temperature.
• Look for error codes on tankless units.
• Avoid repeated resets; it’s a safety trip.
