What Lake Stevens Does to a Tankless Heater
Hard freezes are occasional in Lake Stevens, and that's when we get calls about frozen lines and split fittings. The rest of the year it's mostly ignition parts and flow sensors.
Local factors in Lake Stevens
- Garage-mounted heaters. Most heaters in this area hang in the garage, typically with a short vent out through the closest exterior wall.
- Winter freezes. Built-in freeze protection guards the heater's internals, not the bare piping below it. Lines left uninsulated are where most winter damage begins.

Nearly every request for tankless water heater repair in Lake Stevens, WA starts with a symptom on this list and finishes with a single replaced component or a flush.

Clicks, but no flame
Clicking with no flame means something in the gas, ignition or vent path is off. We work through all three.

Dripping from the cabinet
Leaks start at service valves, pipe joints, the pressure relief valve, the condensate drain or a cracked exchanger.

Code 10 or E110 on the panel
The burner shuts down on an air or exhaust fault to keep you safe. We clear and inspect both intake and exhaust.
Cuts out partway through a shower
Flow has fallen under the firing minimum, usually from a plugged screen, aerator or shower valve cartridge, or a sensor reading low.
Water isn't as hot anymore
Mineral scale in the exchanger, a gas supply that sags, or a temperature sensor giving a false reading.
Rinnai showing LC
That's the scale warning. The exchanger is due for a descale, and it shouldn't wait long.

Keep It Running or Replace It in Lake Stevens?
A gas tankless heater that gets regular flushes often keeps going for two decades or more, so one bad part almost never justifies a new unit. Once a heater is past 15 years and its exchanger fails without warranty coverage, replacement starts to make more sense.
Grab the model and serial numbers from the rating plate and ring (888) 987-0567. Age plus symptoms is usually enough to settle the repair question over the phone.
