Noticed green light was not on anymore (it did work at one time) on my LWCO. Hard to make out if amber light was on with the light in my mech. room. Ran boiler and all was well. Decided to pull LWCO, clean probe and re install. Probe was not too dirty. After reinstall of cleaned LWCO it works, test button works....but green LED does not come on anymore. Is this an issue with the LED burning out? Has anyone else had this problem, should I replace the LWCO seeing as it is only a year old, maybe less. Otherwise 2012 loch mod/con runs fine for DHW cycles.
