Tankless Units in Washougal Homes
Most Washougal homes keep the tankless on a garage wall. Mild, damp winters are easy on units, but the occasional deep freeze catches exposed lines.
What we run into in Washougal
- Garage installs. Many units here are mounted on a garage wall, which keeps them reachable for service and out of the worst weather.
- Freeze damage. Cold snaps do damage here when the power drops overnight. A frozen line or a cracked fitting under the unit is a repair we see after every deep freeze.

These are the faults behind most calls for tankless water heater repair in Washougal, WA. The display usually points at one of them.

Code 11, E003 or 111
No ignition usually means gas pressure, a worn igniter, a dirty flame rod or a blocked vent. Each is tested.

Water under the unit
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.
Hot, then cold, then hot
A short cold burst after the tap reopens is normal start-up. Swings during one shower point to low flow, scale or a failing flow sensor.
Shuts off mid-shower
Flow drops below what the unit needs to keep firing: a clogged filter, aerator or shower cartridge, or a sensor misreading.
Cold at one tap only
Usually a mixing valve or a cold-water crossover at that fixture, not the heater.

Tell us the brand, roughly how old the unit is and what it is doing when you call (380) 273-8196. If a repair is a poor spend, you will be told so.
