The Kohler 5ECD on my 2008 310 has been running just above 200 hours but won't work properly since this summer. It was shutting down with LOC code frequently. I checked the water flow and temperature and they were all good. I thought it might be the water pressure sensor issue. I jumpped the water sensor and the gen set went back to normal. However, I got the same LOC code again after I replaced a new pressure sensor. The water flows ok at normal temperature. Does my get set has a real LOC problem? Does anyone have the same experience? Where I should investigate further? The service guy has been working on my gen set for 2 weekends but could not find the the real issue. I do need help some help here...
