Are you in Sweden then Vito? If I recall correctly the UPO brand is only sold there.
Can you get me a model number off the machine?
I would imagine that it is probably a pressure switch issue, possibly a blockage preventing the machine from reading the correct fill level. But it’s just an educated guess.
I’ve asked if I can get any more info on it as it’s not coming up for me since it isn’t sold in the UK. I’ll hopefully get some info at the start of the week.
