For the fourth time since installation two years ago the Eberspächer D5 heaterunit went in to error,this time with faultcode 14(to big temp difference between flamesensor and overheating sensor).
Not until we had it all out cleaning loads of soot again, it could be reinstalled and now again working flawless. For some reason it seems to be storing loads of soot needing regular stripdown and cleaning. Like before all fuelfilters for the unit was clean which means contaminated fuel could hardly be the reason ?
As usual nowadays faultsearch starts with a laptop connected to your equipment. For that reason teamviewer is good to have for communicating with experts on the field.
