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

If your water heater still won’t heat after pressing reset, the high‑limit likely tripped again. Common causes include a failed heating element or thermostat (electric), an unlit pilot or bad thermocouple (gas), sediment insulating the burner/tank, or a power/gas supply issue. We repair elements, thermostats, pilot assemblies, and perform full flushes on all tank and tankless models. Annual drain-and-flush helps prevent repeat trips. We serve Denver and nearby cities.

Quick checks:

• Check the breaker or gas shutoff.
• For gas, confirm the pilot is lit.
• After reset, allow time to reheat.
• If it trips again, stop and call.
