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

If your water heater still won’t heat after pressing the reset, likely causes include a failed heating element (electric), an unlit pilot or dirty gas burner (gas), or heavy sediment that blocks heat transfer. Loose fittings or a leaking pressure‑relief valve can also reduce performance. Systems near end of life (about 8–10 years) may not recover without repair or replacement.

Quick checks:

• Confirm power is connected and the breaker/fuse is good.
• Verify the pilot light is lit (gas).
• Listen for hissing noises.
• Consider sediment buildup.
