READ THIS before you ignore that code 🚨
That blinking code on your tankless water heater?
It’s not random. It’s a warning.
And if you ignore it… it can cost you thousands.
Here’s what we see all the time:
🔧 Code 11 – Ignition failure
→ leads to system strain + part failure
🔧 Code 12 – Flame loss
→ repeated shutdowns that wear out your unit
🔧 Code 29 – Condensate issue
→ moisture buildup that can damage internal components
Homeowners reset the system…
and keep using it like nothing’s wrong.
Meanwhile, the damage gets worse behind the scenes.
What starts as a small issue can turn into:
❌ major component failure
❌ no hot water
❌ full system replacement
Don’t wait until it’s an emergency.
If your tankless system is showing a code, get it checked by a pro.
