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

If your water heater still won’t heat after pressing the reset, the likely causes are a failed thermostat or heating elements (electric) or issues with the pilot light or gas valve (gas). Sediment buildup can also reduce heating. Because water heaters can be hazardous if handled improperly, schedule a professional diagnostic.

Quick checks:

• Verify the breaker is on (electric).
• Confirm gas is on and pilot is lit (gas).
• Look for leaks or discolored water.
• Note creaking/rumbling sounds (often sediment).
