Ignition Failure Repair in Fremont, 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 common hidden cause when a tankless unit replaced a tank. We correct the issue so the unit lights reliably.
Tankless Descaling and Flushing in Fremont
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 a smart move for most homes on hard water.
Flow Sensor and Thermistor Repair in Fremont
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.
Electric Tankless Water Heater Repair in Fremont, CA
Electric tankless units offer a compact solution but can encounter problems with heating elements or circuit breakers.

We provide specialized repair services for Noritz units in Fremont, CA, ensuring proper combustion, water flow and exhaust, which are crucial for safe and efficient operation.
Condensing Tankless Repair in Fremont, CA
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.
No Hot Water Tankless Repair in Fremont
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.

Frequently Asked Questions About Tankless Water Heater Repair in Fremont
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.
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.
While some basic troubleshooting, like checking the power supply or gas valve, can be done, most tankless water heater repairs require specialized tools and knowledge. Attempting DIY repairs on gas or electrical components can be dangerous and void your warranty. It is always best to call a licensed plumber.
Minor tankless water heater repairs, such as replacing a sensor or igniter, typically do not require a permit in Fremont. Major component replacements, changes to the gas or water lines, or replacing the entire unit may require a plumbing permit to ensure code compliance.
Yes, regular maintenance, particularly annual descaling where water is hard, is important for tankless water heaters. It prevents mineral buildup, maintains efficiency and extends the lifespan of the unit, often heading off costly repairs.
Yes, FBL Plumbing stands behind its work. All our tankless water heater repairs come with a satisfaction guarantee and a warranty on both parts and labor. We will provide specific warranty details with your repair estimate.
Frequent 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.
