    Merry Christmas to all

    Have been using my Webasto heater for some 6 years without problems.
    Just started giving out some trouble codes, I Idecided it is time for long overdue service/repair
    Replaced filter, glow plug, burner, gaskets, clamps, connectors as per recommendations.
    Now I get a F01(one blink code). The weird part is that when I start it the first time(and every time after) it works flawlessly. Only after it reaches the desired temperature and shuts down until ready to restart by itself, it trys 2 times and then gives up with F01. At that point if I manually shut it down and then turn it on It fires up immediately as if nothing happened. Until next restart

    Anyone experienced this and how to fix it

    Thanks

    I had one do that, turned out to be poor electrical connection to batteries.
