Tankless Units in Kennewick Homes
In Kennewick, units usually hang in the garage of a craftsman or newer house. The water is mostly soft, so faults tend to be parts, not scale.
What we run into in Kennewick
- 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 Kennewick, WA, from ignition codes to drips under the cabinet.
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.
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.

Call (380) 273-8196How much does tankless water heater repair in Kennewick, WA cost?
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.
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.
What is the most common problem with tankless water heaters?
Scale in the heat exchanger, followed by ignition faults and flow sensor or filter problems. All three usually show up as a code or as water that won't stay hot.
Can a tankless water heater be repaired?
Yes, in most cases. Igniters, flame rods, flow sensors, thermistors, fans, gas valves and boards are all replaceable, and scale can be descaled. A leaking heat exchanger on an old unit is the main exception.
