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. Electric units may have burnt heating elements or a tripped breaker. Gas units may have a bad thermocouple, dirty flame sensor, or a closed gas valve. Heavy sediment can overheat the tank and trip the safety. Tankless models may be undersized or showing an error code. We service all types and provide same-day, free estimates in Roanoke and nearby.

Quick checks:

• Verify the breaker is on (electric).
• Confirm gas is on and the pilot/igniter works (gas).
• Look for error codes (tankless).
• Listen for boiling or popping that suggests sediment.
