Flow Sensor and Thermistor Repair in Alhambra
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 faulty parts. Temperature becomes steady again once readings are accurate.
Emergency Tankless Water Heater Repair in Alhambra, CA
A sudden loss of hot water can be an emergency, especially on a cold morning in Alhambra, CA. FKM Plumbing offers emergency tankless water heater repair to address critical 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 fast response team works quickly to restore your hot water, often on the same day.
Gas Tankless Water Heater Repair in Alhambra
Gas tankless water heaters require correct gas pressure and proper ventilation for safe operation. Issues can range from gas valve malfunctions to carbon monoxide sensor errors. Our certified technicians in Alhambra perform thorough diagnostics on gas lines, igniters and exhaust systems, so your unit is both functional and safe.
Recirculation Pump Repair in Alhambra
Many tankless systems use internal or external recirculation to deliver hot water faster. 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.
Tankless Descaling and Flushing in Alhambra
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.
Commercial Tankless Water Heater Repair in Alhambra
Commercial tankless water heaters in Alhambra face heavier usage and require robust repair solutions. Whether it is for a restaurant, hotel or office building, we understand the importance of maintaining hot water availability. Our commercial tankless water heater repair services address larger capacity units, complex manifold systems and often more serious scaling issues. We prioritize fast, efficient service to minimize disruption to your business operations.
Tankless Water Heater Error Code Diagnostics in Alhambra, CA
Modern tankless water heaters display error codes to flag specific problems, from flow rate issues to combustion errors. Our experts in Alhambra, CA are trained to interpret these codes accurately, using specialized 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, among others.
Condensing Tankless Repair in Alhambra, 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 confirm proper drainage. PVC venting is also checked for slope and sagging.
