Tankless Units in Olympia Homes
Garage-mounted units are the norm in Olympia. Damp air and spiders in the intake are small things that cause real shutdowns.
What we run into in Olympia
- Garage installs. Here the unit typically lives in the garage, so the inlet filter and the service valves are easy to get at when it needs attention.
- Freeze damage. A hard freeze can split the pipes feeding a unit. Its built-in freeze protection only works while the unit still has power and gas.

The list below covers what we find on most visits for tankless water heater repair in Olympia, WA, from ignition codes to drips under the cabinet.

Code 11, E003 or 111
A unit that clicks without lighting has an ignition, gas or venting fault, and each is checked in turn.

Drip from the cabinet
Water below a tankless can be a valve, a fitting, condensate or a failed exchanger. The source decides the cost.

Venting fault
Venting codes mean the unit can't breathe: a blocked termination, a nest, snow or a vent run that's too long.
Cold at one tap only
Usually a mixing valve or a cold-water crossover at that fixture, not the heater.
LC code on a Rinnai
The unit is reporting scale buildup. It needs a descale, and soon.
Frozen after a cold night
Lines feeding the unit froze, or freeze protection lost power.

The median home here dates from 1981, so tankless units are a mix of original-era installs and newer replacements, and an older unit that has never been descaled is a frequent find. Olympia is about evenly split between owners (around 49%) and renters, so calls come from homeowners and from landlords and property managers alike.
