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

Resetting the button restores power, but no hot water usually means an underlying fault remains. Common causes include a tripped breaker, a failed thermostat or heating element, gas supply or igniter/pilot issues, or heavy sediment that needs a tank flush. Flushing the tank or replacing faulty components can solve the issue and extend lifespan. Our plumbers provide diagnostic inspections, same-day service in many Phoenix-area neighborhoods, and up-front pricing with no overtime fees.

• Check breaker or gas shutoff.
• Verify pilot/igniter.
• Look for leaks or rust-colored water.
