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

Resetting the button usually won’t restore hot water if another part has failed. Common causes include a tripped breaker, failed heating elements or thermostats (electric), an extinguished pilot or bad igniter (gas), or heavy sediment that overheats the tank. Tankless units may show flow, venting, or gas supply error codes. We serve Denver, Aurora, and Westminster with same-day options when you call early.

Quick checks:

• Make sure the water heater breaker is on.
• Relight the pilot or test the igniter (gas).
• Flush sediment if maintenance is overdue.
• Note any on-screen error code.
