About Tankless Water Heater Overheating Repair

Tankless water heaters feature multiple redundant safety sensors designed to shut down the burner if water or metal temperatures exceed safe limits in Calumet City, Illinois. When thermal wrap fuses melt, high-limit bi-metal switches trip, or error codes 14 or 16 appear, the heater shuts down completely to prevent house fires. Overheating is typically caused by heavy mineral scale insulating copper fin tubes, low water flow, or a stuck gas valve. Our certified technicians inspect thermal fuses, perform emergency descaling flushes, and replace high-limit safety switches. We eliminate overheating causes and restore safe, reliable heating.

Error Code 14 or 16 Lockout

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.

Elena Rostova

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.
