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

If your water heater still won’t heat after pressing the reset, a failing thermostat or gas control valve is likely. Pilot light outages can also stop heating. Sediment, rust, or corrosion can reduce heat transfer and trigger issues. Leaks or changing water temperature are signs you need professional diagnosis. Cranney services gas, electric, tank, tankless, heat pump, and indirect systems.

Quick checks:

• Look for pilot light outages.
• Note leaks, noises, rusty water, or temperature swings.
• If problems persist, schedule a repair.
