I've been browsing another forum and there is a suggestion that excess heat, with a Combi in an enclosed space, might be blowing the 240v fuse, rendering the unit inoperative on electric....but gas ok.
furthermore, the operation in mixed mode is seen as being the culprit for this specific issue.
while I could see that the unit might trip the overheat protection, if tightly enclosed, I can't see it being responsible for blowing fuses?
my own unit (Combi 6e) is in a tight location, under the fridge/freezer, and I have used it on all modes over the past (near) two years without issue....
I have a German van, the vans being discussed are AutoSleepers that 'interact' with Sargent electrics...
I'm told other brands have has this issue, but googling has on.y highlighted overheating or, perhaps, PSU failure...
any views?
