We have enjoyed our Paloma tankless water heater care free for over 10 years. Recently on occasion it has taken 2 or 3 times turning water off and on again to get the heat going. We get an error code 11 when it fails to ignite. So far it has not failed to ignite after 2 or 3 tries. I've never done any maintenance on it. I did the installation myself along with the electrical changes for high altitude operation. Do these symptoms indicate a course of action I can take to correct the trouble myself?
