Condensing Tankless Repair in Seattle, WA
Condensing tankless heaters, such as many Navien models, extract extra heat from exhaust and produce condensate. Clogged condensate traps, failed neutralizers and blocked drains can shut the unit down. We clean the trap, replace the neutralizer media and verify proper drainage. PVC venting is also checked for slope and sagging.
Emergency Tankless Repair in Seattle
A tankless unit that leaks internally or shows a fault you cannot clear needs prompt attention. We put first no-hot-water calls and arrive with common sensors, igniters and filters. If a major component like a heat exchanger has failed, we check warranty coverage and order the part. We can often restore partial operation in the meanwhile.
Tankless Repair vs Replacement Cost in Seattle, WA
Descaling service usually costs $175 to $350, and sensor or igniter repairs run $250 to $600. Heat exchanger replacement can cost $800 to $1,500 or more unless covered by warranty. A new tankless unit installed usually ranges from $3,000 to $5,500. We compare these costs against the age and condition of your unit.

FHN Plumbing offers expert electric tankless water heater repair in Seattle, WA, addressing electrical faults, confirming proper wiring and replacing faulty elements to restore your hot water supply safely and efficiently.
Pilot Light & Ignition Repair in Seattle, WA
For gas-fired tankless water heaters, a malfunctioning ignition system can completely stop hot water production. Our team in Seattle, WA diagnoses issues with igniters, flame sensors and gas valves. We confirm proper gas pressure and ventilation are maintained for safe and efficient operation. Timely repair of these components prevents dangerous gas problems and restores your unit's ability to heat water on demand.
No Hot Water Tankless Repair in Seattle
When your tankless unit fails to produce hot water, it is often due to issues with the ignition, gas supply or a clogged heat exchanger. Our technicians in Seattle will carefully diagnose the root cause, whether it is a faulty igniter, a pressure sensor malfunction or mineral buildup. We carry common replacement parts for quick fixes, restoring your continuous hot water supply efficiently. We also check for proper venting, which is essential for the safe operation of your unit.
Ignition Failure Repair in Seattle, WA
If your tankless unit will not fire, the cause may be a dirty flame rod, a bad igniter, low gas pressure or a blocked intake. We test each component and measure gas pressure at the inlet. Undersized gas lines are a frequent hidden cause when a tankless unit replaced a tank. We correct the issue so the unit lights reliably.
Flow Sensor and Thermistor Repair in Seattle
Tankless heaters rely on flow sensors to start and thermistors to regulate temperature. A dirty inlet filter or failed sensor causes no hot water, fluctuating temperature or the unit turning off mid-shower. We clean filters, test sensor readings and replace faulty parts. Temperature becomes steady again once readings are accurate.

Frequently Asked Questions About Tankless Water Heater Repair in Seattle
The cost of tankless water heater repair in Seattle varies a lot depending on the issue, ranging from $150 for minor fixes like sensor replacement to $600 or more for complex repairs involving heat exchanger descaling or major component replacements. We provide a detailed estimate after identifying the specific problem.
Codes point to specific faults such as ignition failure, flame loss, overheating or scale buildup. Each brand uses its own code list, and we use manufacturer guides to interpret them.
Regular maintenance, particularly annual descaling, is important for tankless water heaters in homes with hard water. It prevents mineral buildup, maintains efficiency, extends the lifespan of the unit and helps avoid costly repairs by catching small issues early.
Most repairs and descaling are done in one to three hours. If a part must be ordered, we typically return within a few business days.
We stand behind our tankless water heater repairs with a solid warranty on both parts and labor. The specific warranty period will be discussed with you before any work begins, providing you peace of mind.
Minor tankless water heater repairs, such as replacing a sensor or igniter, typically do not require a permit in Seattle. Major component replacements, changes to the gas or water lines, or replacing the entire unit may require a plumbing permit to confirm code compliance.
Common causes of failure include mineral buildup from hard water, ignition problems, faulty flow sensors, clogged air filters, exhaust venting issues and electrical component failures. Regular maintenance, including descaling, can prevent most of these problems.
Some homeowners do with a kit if service valves are installed. Diagnosing error codes and replacing sensors, igniters or gas components should be left to a pro.
