Ignition Failure Repair in Bothell, 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 common hidden cause when a tankless unit replaced a tank. We correct the issue so the unit lights reliably.
Tankless Descaling and Flushing in Bothell
Hard water leaves calcium and magnesium scale inside the heat exchanger, restricting flow and causing overheating. Many units warn of this with scale codes, such as the LC code on Rinnai models. We connect a circulation pump to the service valves and run a descaling solution through the exchanger. Annual descaling is wise for most homes on hard water.
Emergency Tankless Water Heater Repair in Bothell, WA
A sudden loss of hot water can be an emergency, especially on a cold morning in Bothell, WA. FHN Plumbing offers emergency tankless water heater repair to address serious failures promptly. We are available to troubleshoot issues like major leaks, complete system shutdowns or persistent error codes that prevent any hot water production. Our rapid response team works quickly to restore your hot water, often on the same day.
Recirculation Pump Repair in Bothell
Many tankless systems use internal or external recirculation to deliver hot water more quickly. Pump failures, check valve problems or wrong schedule settings can cause long waits or lukewarm water. We test the pump, check valves and controls and set the schedule to match your daily routine. A properly tuned system saves both water and gas.
Tankless Water Heater Descaling Service in Bothell
Hard water can lead to mineral buildup, or scaling, in your tankless water heater's heat exchanger, cutting efficiency and eventually causing breakdowns. Soft water can be mildly corrosive to copper over time, which sometimes shows up as pinhole leaks in older supply lines. Our descaling service in Bothell involves flushing the unit with a specialized cleaning solution to dissolve these mineral deposits. This preventative maintenance and repair step is crucial for extending the lifespan of your tankless heater and keeping it at peak performance.
Tankless Repair vs Replacement Cost in Bothell, WA
Descaling service typically 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.
Flow Sensor and Thermistor Repair in Bothell
Tankless heaters use 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 failed parts. Temperature becomes steady again once readings are accurate.
Tankless Water Heater Error Code Diagnostics in Bothell, WA
Modern tankless water heaters display error codes to indicate specific problems, from flow rate issues to combustion errors. Our experts in Bothell, WA are trained to interpret these codes accurately, using dedicated diagnostic tools to pinpoint the exact component failure. This accuracy allows us to quickly order the correct parts and perform targeted repairs, saving you time and money. We address codes related to burner failures, fan issues and temperature sensor errors, and more.

Frequently Asked Questions About Tankless Water Heater Repair in Bothell
The cost of tankless water heater repair in Bothell 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 diagnosing the specific problem.
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.
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.
With regular descaling, tankless heaters often last 15 to 20 years. Without maintenance in hard water, problems can start within a couple of years.
Regular professional maintenance, including descaling and checking all connections, is the best defense. Installing a whole-home water softener can also greatly reduce mineral buildup in areas with very hard water.
While some basic maintenance like filter cleaning can be done by homeowners, complex repairs involving gas lines, high voltage electricity or intricate internal components should always be left to a licensed professional. DIY attempts can be dangerous and void warranties.
Fluctuating temperatures can come from low flow rates, a dirty inlet filter, a failing flow sensor or scale on the heat exchanger. Crossed hot and cold lines at a fixture can cause it too.
Many tankless heat exchangers carry long warranties, while other parts usually have shorter coverage. Warranties may require proof of maintenance, which we document.
