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

Resetting rarely fixes no-heat; it points to an underlying fault. Common causes include sediment buildup that blocks heat transfer and an aging tank (often 10+ years) that can’t keep up. Warning signs are fluctuating or lukewarm water, odd sounds, rusty or cloudy water, leaks, and reduced pressure. If these persist or you’ve had frequent breakdowns, replacement may be the better option for reliable hot water. We help homeowners in Novato, San Rafael, and Petaluma.
