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

If the reset button doesn’t restore hot water, common culprits are dirty pilots or heating elements, sediment buildup, or a failing thermostat. Sediment can block heat transfer, and dirty elements or pilots may keep the unit from firing. If the unit is older or using outdated technology, replacement may be more practical after inspection.

Quick checks:

• Verify the breaker is ON.
• For gas units, confirm the pilot/igniter is working.
• Listen for rumbling (sediment) and look for leaks or discolored water.
• If the reset trips again, stop and call.
