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

If the reset button keeps tripping, a fault is still present. Electric heaters often have a failed heating element or thermostat. Gas units may have an unlit pilot, bad igniter, thermocouple, or a faulty gas valve. Heavy sediment or scale can overheat the tank and trip the limit. Tankless models can lock out with error codes. Power or gas supply issues also stop heating. Cole Services offers same-day diagnostics and tune-ups with a 6‑month no-breakdown guarantee.

Quick checks:

• Check the breaker or fuse.
• For gas, relight the pilot and confirm gas is on.
• Note any error code.
• If it trips again, stop and schedule service.
