When people phone about tankless water heater repair in Woodinville, WA, it is nearly always one of these problems. Each has a short list of causes.

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.
Noisy or whistling
Scale, a struggling fan or a gas regulator issue, each of which shows up on testing.
Error code keeps coming back
A reset only clears the symptom. Repeated ignition or exhaust codes need a visit.
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.
