When a tankless water heater's flame fails to ignite or drops out mid-use, the hot water stops almost instantly. The cause is usually gas, venting, or a sensor, and it is worth diagnosing precisely.
The gas
Low gas pressure, a closed valve, or a dirty burner can prevent the flame from lighting or holding. The unit needs a steady supply to run.
The vent
A blocked intake or exhaust trips the safety and shuts the flame down. mineral-rich water varies by region, and older neighborhoods still run on aging galvanized or copper lines In Citrus Heights, nests and debris in the vent are common culprits.
The sensor
The flame sensor proves the flame is lit, and if it is dirty or failing, the unit shuts off as a safety measure.
The flow
A tankless fires only when enough water flows, so a low-flow faucet or a clogged filter can make it seem like the flame failed.
The service
An annual descale and burner clean prevents most flame failures. A unit that is serviced regularly fails far less than one that is ignored.
