About Rinnai Tankless Water Heater Repair

Rinnai systems are legendary for durability, but hard water minerals and electrical surges can halt heating in Calumet City, Illinois. If your status monitor flashes code 10, 14, or 79, safety interlocks prevent heating until a technician clears the underlying issue. Our licensed technicians specialize in Rinnai Sensei and older V-series units. We clean optical flame sensors, clear condensate traps, and adjust proportional gas control valves. Leaving a scale-choked copper heat exchanger running causes metal fatigue and costly pinhole ruptures. We keep your system heating at peak thermal efficiency.

Common Problems We Solve With Rinnai Tankless Water Heater Repair

Lint or debris in intake venting starves the burner chamber of fresh air in Calumet City, Illinois.

Code 14 Thermal Fuse Break

Overheating melts the protective bi-metal wrap around the heat exchanger.

Code 79 Water Leak Detection

Moisture sensor in the unit base pan detects condensation or joint leaks.

What Our Customers Say

Real reviews from property owners we have helped restore to endless hot water.

Our Navien unit flashed error E003 on a cold morning and stopped heating completely. The technician arrived with the exact OEM flame sensor rod on his truck, tested the gas manifold pressure, and had hot water flowing again within an hour. The diagnostic explanation was clear and pricing was fair.

Our Rheem tankless system kept shutting down during showers with code 12. Two other plumbers told us we needed a new unit, but this team discovered a clogged condensate trap and an oxidized flame sensor. They cleaned the burner assembly and saved us thousands compared to a premature replacement.

Hard water scale choked our Rinnai heat exchanger to the point where shower pressure dropped to a trickle. Their technician hooked up a high-volume descaling pump and circulated food-grade solution for over an hour. The difference in water pressure and heating speed was immediate.
