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 Laguna Niguel, CA, addressing electrical faults, confirming proper wiring and replacing faulty elements to restore your hot water supply safely and efficiently.
Pilot Light and Ignition Repair in Laguna Niguel, CA
For gas-fired tankless water heaters, a faulty ignition system can completely stop hot water production. Our team in Laguna Niguel, CA diagnoses issues with igniters, flame sensors and gas valves. We ensure proper gas pressure and ventilation are maintained for safe and efficient operation. Timely repair of these components prevents hazardous gas problems and restores your unit's ability to heat water on demand.
Flow Sensor and Thermistor Repair in Laguna Niguel
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 accurate.
Tankless Water Heater Descaling Service in Laguna Niguel
Hard water can lead to mineral buildup, or scaling, in your tankless water heater's heat exchanger, cutting efficiency and eventually causing breakdowns. Hard water shortens the life of tankless units, valves, and appliances, which is why many homes in Southern California add softeners or scale filters. Our descaling service in Laguna Niguel involves flushing the unit with a dedicated 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 Descaling and Flushing in Laguna Niguel
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.
Recirculation Pump Repair in Laguna Niguel
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.

Frequently Asked Questions About Tankless Water Heater Repair in Laguna Niguel
The cost of tankless water heater repair in Laguna Niguel, CA can range from $150 to $800 or more, depending on the issue. Simple fixes like sensor replacements might be at the lower end, while major component replacements like a heat exchanger could be higher. We provide a detailed estimate after diagnosis.
Minor repairs usually do not require a permit. If the repair involves significant changes to the gas or water lines, or if the unit itself is being replaced, a permit from the Laguna Niguel building department may be necessary. We handle all necessary permitting for you.
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.
With regular descaling, tankless heaters often last 15 to 20 years. Without maintenance in hard water, problems can start within a couple of years.
This often comes from low gas pressure, a blocked intake or exhaust, a dirty flame rod or overheating from scale. We test each possibility to pinpoint the cause.
Error codes can be caused by a variety of issues, such as low water flow, gas supply problems, ignition failures, exhaust blockages or faulty temperature sensors. Each code corresponds to a specific system malfunction.
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.
We service Navien, Rinnai, Noritz, Rheem, Takagi, A.O. Smith, Bosch, Stiebel Eltron and EcoSmart units, among others.
