My tank-less water heater stopped working with an error code 11.
I had somebody out to take a look at it. relatively quickly we went through the troubleshooting steps and concluded the flame rods/sensors were the issue. We cleaned them and it started working again.
He is recommending that we replace them, do a dry cleaning and move the gas line because the regulator is only 6 inches from the bottom of the unit.
He claims that a new building code now requires it to be at least 3 feet away. I have no idea if this is true or if it needs to be done. I do believe the rods needs to be replaced (sorry if this is the wrong name for the three small metal rods that light the flame and detect if it is working.) The house is only 4 years old.
All said, he wants to come back and do all of this for $600. The parts are under warranty, so Rinnai is shipping them free. I don't know if I should just pay for him coming out and just install the new parts myself, or actually let him do the extra work that is needed.. and if so, if $600 is reasonable? If it is I don't mind paying him, I just hate the idea of being up sold.
