Hi Eric
I have a takagi th3-dv-p (propane) water heater and got error 111 (ignition issues) while it was running (we were using it for a few continuous hours). Takagi asked me to flush the heater and then reset it. I used your procedure above to reset but it didn’t resolve the issue. Gas pressure is fine. Any ideas? Thank you !
Hey, Adam…
First off, do you flush the unit? If not, flush the unit first. Then, try the resetting procedure. Adam, there are multiple reasons that cause the Takagi to pop up the error code 111. Fortunately, I covered a guide on this. I recommend you read the following article first, resolve those issues, and then try to reset the unit:
