Tankless Units in Pasco Homes
Garage-mounted units are the norm in Pasco. Damp air and spiders in the intake are small things that cause real shutdowns.
What we run into in Pasco
- 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.

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

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
Drips come from service valves, fittings, the relief valve, the condensate line or the heat exchanger itself.

Code 10 or E110
An air or exhaust code stops the burner for safety. The intake and exhaust are cleared and checked.
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.

Fix It or Retire It? Deciding in Pasco
Igniters, flame rods, sensors, fans, gas valves and boards are worth replacing on almost any unit. The hard call is a leaking or cracked heat exchanger on an older unit, because that part can approach the price of new.

Most repairs cost an estimated $150 to $800, depending on the part. Descaling alone is estimated at $150 to $350, and a heat exchanger at $1,000 to $2,500. Freeze repairs depend on what split, and are priced once the damage is seen.

Usually, yes. Nearly every part on a tankless unit can be replaced, and a scaled exchanger can be cleaned. The exception is an old unit whose heat exchanger has started to leak.
Is there a reset button on a tankless water heater?
Most units reset by switching power off and on, or through the controller. A reset clears the code, not the cause; ignition and exhaust codes that return need a repair visit.

Gas units commonly run 20 years or more when they are flushed on schedule. Electric tankless units tend to last closer to 7 to 10 years.
