Flow sensors, filters & leaks
Units that shut off mid-shower or drip from below get the flow sensor, filter, valves and fittings sorted.

- 01
Error history read

Tankless Problems We Fix Around Tualatin
Most requests for tankless water heater repair in Tualatin, OR start with one of the symptoms below, and most end with a single part or a descale.

Unit won't light
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
An air or exhaust code stops the burner for safety. The intake and exhaust are cleared and checked.
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.
Can't tell which one you have? Read us the display and describe the water, and the likely fault comes back on the call.

Fix It or Retire It? Deciding in Tualatin
Gas tankless units commonly last 20 years or more with flushing, so a single failed part rarely means a new heater. A failed exchanger outside its warranty, on a unit past 15 years, is where replacement starts to win.

How long does a tankless water heater last?

Why is my tankless water heater not turning on?
Check for power at the outlet and that the gas valve is open. Beyond that it is usually low flow, a clogged inlet filter, a failed flow sensor or an ignition fault.
Why does my tankless water heater go hot then cold?
A second or two of cold after the tap reopens is normal start-up. If the water swings while it runs, look at low flow, scale or the flow sensor.
