Flow Sensor and Thermistor Repair in Salem
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 failed parts. Temperature becomes steady again once readings are correct.

Tankless Descaling and Flushing in Salem
Hard water leaves calcium and magnesium scale inside the heat exchanger, limiting 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.
Gas Tankless Water Heater Repair in Salem
Gas tankless water heaters require precise gas pressure and proper ventilation for safe operation. Issues can range from gas valve failures to carbon monoxide sensor errors. Our certified technicians in Salem perform thorough diagnostics on gas lines, igniters and exhaust systems, so your unit is both functional and safe.
Rinnai Tankless Water Heater Repair in Salem, OR
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 Salem, OR are skilled at Rinnai tankless water heater repair, focusing on descaling services, fan motor replacements and resolving issues with gas valve assemblies. We make sure your Rinnai system continues to provide reliable, on-demand hot water, following manufacturer specifications.
Recirculation Pump Repair in Salem
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.
Condensing Tankless Repair in Salem, OR
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.

Frequently Asked Questions About Tankless Water Heater Repair in Salem
The cost of tankless water heater repair in Salem varies widely depending on the issue, ranging from $150 for minor fixes like sensor replacement to $600 or more for complex repairs involving heat exchanger descaling or major component replacements. We provide a detailed estimate after identifying the specific problem.
While some basic troubleshooting, like checking the power supply or gas valve, can be done, most tankless water heater repairs require special 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.
Many tankless heat exchangers carry long warranties, while other parts usually have shorter coverage. Warranties may require proof of maintenance, which we record.
Minor repairs typically 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 Salem building department may be necessary. We handle all necessary permitting for you.
We stand behind our tankless water heater repairs with a comprehensive warranty on both parts and labor. The exact warranty period will be discussed with you before any work begins, providing you peace of mind.
In homes with hard water and no softener, once a year is a good rule. Homes with a softener may go longer, but annual inspection is still wise.
We repair Navien, Rinnai, Noritz, Rheem, Takagi, A.O. Smith, Bosch, Stiebel Eltron and EcoSmart units, among others.
Most repairs and descaling are done in one to three hours. If a part must be ordered, we typically return within a few business days.
