Common A.O. Smith Problems We Fix

A.O. Smith gas water heaters that won't hold a pilot flame typically have a failed thermocouple or thermopile. These safety components cut gas flow when they can't detect a flame. We replace them .

Electric A.O. Smith units with no hot water usually have a tripped reset button (high-limit switch) or a failed heating element. We test the reset, elements, and thermostats to identify the exact cause.

A.O. Smith tankless error code E5 indicates a temperature sensor fault. This requires testing the sensor resistance and replacing if out of specification.

Rusty or discolored water from an A.O. Smith tank usually means the anode rod is depleted and the tank interior is corroding. If caught early, anode rod replacement can extend the tank's life. If the tank itself is rusting, replacement is needed.

An A.O. Smith tank that is leaking from the bottom typically has internal corrosion and requires replacement. Leaks from the top (around fittings or the T&P valve) can often be repaired without replacing the unit.

Frequently Asked Questions

To relight an A.O. Smith pilot: turn the gas valve to Pilot, press and hold the igniter button while pressing the pilot button, hold for 30–60 seconds after the pilot lights, then release and turn to your desired temperature. If the pilot won't stay lit, the thermocouple likely needs replacement.

The status light on an A.O. Smith gas water heater blinks to indicate its operating status. One blink every 3 seconds means normal operation. Rapid blinking or multiple blinks in a pattern indicate an error code — count the blinks and call us for diagnosis.

A.O. Smith tank water heaters typically last 8–12 years in Los Angeles. Their shorter lifespan compared to Bradford White or Rheem is partly due to the harder water in the LA area — annual flushing and anode rod maintenance extends lifespan significantly.
