last time when connected to shore power I have used dishwasher and after one minute all the power went off. Including the shore power unit. This did not happened when running air conditioning or washing machine. Interesting enough I have turned on generator put the power on and dishwasher was running without interruption. Power was on all the time. Next time I tried again and shore power went off, again generator ok. Before going in to deep investigation is there any idea on the forum what might be the issue? Grounding is one that comes to my mind
