Ignition Failure Repair in Los Angeles, CA
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 every time.
Flow Sensor and Thermistor Repair in Los Angeles
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 failed parts. Temperature becomes steady again once readings are correct.
Electric Tankless Water Heater Repair in Los Angeles, CA
Electric tankless units offer a compact solution but can encounter problems with heating elements or circuit breakers. FKM Plumbing offers professional electric tankless water heater repair in Los Angeles, CA, addressing electrical faults, ensuring proper wiring and replacing faulty elements to restore your hot water supply safely and efficiently.
Recirculation Pump Repair in Los Angeles
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 routine. A properly tuned system saves both water and gas.
No Hot Water Tankless Repair in Los Angeles
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 Los Angeles will thoroughly diagnose the root cause, whether it is a faulty igniter, a pressure sensor malfunction or mineral buildup. We carry common replacement parts for fast fixes, restoring your continuous hot water supply efficiently. We also check for proper venting, which is crucial for the safe operation of your unit.
Tankless Descaling and Flushing in Los Angeles
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.
Navien Tankless Water Heater Repair in Los Angeles
Navien units are known for their advanced condensing technology but can sometimes develop issues with their circulation pump or exhaust systems. FKM Plumbing provides specialized Navien tankless water heater repair in Los Angeles, addressing common problems like ignition failures or condensate drain blockages.

Municipal water across much of Southern California is hard, leaving chalky scale on faucets, showerheads, and inside water heater tanks. Tankless heaters scale up when water is hard, so careful repair and regular descaling are what keep these efficient units running for their full lifespan.

Frequently Asked Questions About Tankless Water Heater Repair in Los Angeles
Most tankless repairs cost between $175 and $600, depending on the part. Descaling service often runs $175 to $350, while heat exchanger replacement can exceed $800 if not under warranty. We quote before starting.
Typical signs include inconsistent hot water, a sudden loss of hot water, strange noises like banging or popping, a rotten egg smell or error codes displayed on the unit. Any of these symptoms warrant a professional inspection.
With regular descaling, tankless heaters often last 15 to 20 years. Without maintenance in hard water, problems can start within a couple of years.
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.
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.
Minor tankless water heater repairs, such as replacing a sensor or igniter, usually do not require a permit in Los Angeles. Major component replacements, changes to the gas or water lines, or replacing the entire unit may require a plumbing permit to ensure code compliance.
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.
While some basic maintenance like filter cleaning can be done by homeowners, complex repairs involving gas lines, high voltage electricity or delicate internal components should always be left to a licensed professional. DIY attempts can be dangerous and void warranties.
