Customer had the electricity go out about a week and a half ago, the generator kicked on around 6pm and ran until about 2am the next day and kicked an error of 1603 and would not start back up. The installers of the generator called generac and they asked to have the gas pressure tested, upon testing the unit has a water column of 11.5 when the unit is running so gas levels are optimal. Called the installers of the generator and informed them so that they can call generac and get closer to getting this issue solved.
