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

Resetting the button won’t fix issues like sediment buildup, a failed pilot light, incorrect wiring, poor ventilation, or a stuck pressure valve. Leaks, rust, cracks, or loose connections can also stop heating. Tank models often need a flush to remove sediment. Tankless units can fault if maintenance is overdue. Our Valparaiso and Chesterton plumbers can perform a multi-point inspection to confirm the exact cause and restore hot water.

• Check the pilot light (gas).
• Confirm the temperature setting.
• Look for leaks or rust.
• Ensure vents are clear; schedule a flush if sediment is suspected.
