Flow Sensor and Thermistor Repair in Nicholasville
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 Nicholasville
Hard water can lead to mineral buildup, or scaling, in your tankless water heater's heat exchanger, reducing efficiency and eventually causing breakdowns. Water softeners are a popular upgrade in Kentucky homes, protecting tank water heaters, faucets, and appliances from mineral buildup. Our descaling service in Nicholasville 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.

Rinnai is a popular tankless brand, and its units can face challenges such as scaling from hard water or issues with their flame rod. Our technicians in Nicholasville, KY are adept at Rinnai tankless water heater repair, focusing on descaling services, fan motor replacements and fixing issues with gas valve assemblies. We make sure your Rinnai system continues to provide reliable, on-demand hot water, following manufacturer specifications.
Emergency Tankless Water Heater Repair in Nicholasville, KY
A sudden loss of hot water can be an emergency, especially on a cold morning in Nicholasville, KY. BFK 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.
Emergency Tankless Repair in Nicholasville
A tankless unit that leaks internally or shows a fault you cannot clear needs prompt attention. We put first no-hot-water calls and arrive with common sensors, igniters and filters. If a major component like a heat exchanger has failed, we check warranty coverage and order the part. We can often restore partial operation in the meantime.
Condensing Tankless Repair in Nicholasville, KY
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 inspected for slope and sagging.
Recirculation Pump Repair in Nicholasville
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 daily routine. A properly tuned system saves both water and gas.

Ignition Failure Repair in Nicholasville, KY
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 every time.
