Problem: My Eccotemp i12 LP/NG tankless water heater won't start. I've replaced the Flow Meter Sensor, checked to be sure the gas is on, water is flowing and the screen powers up, but there are no audible clicks.
Most likely fix: Replace the computer board. Sounds like it could be an ignition issue. The i12 computer board has the ignition pack embedded into the board, so replacing the board will most likely fix the issue.
