Been using it for a while but recently when I tried to froth the milk for for a cappuccino it remains flat. Bought a new frother, same resault, so bought some milk from the Coop today and it works fine.
They is normally a couple of weeks, twice a year when the fat content of most milk changes and stops steaming as per normal. As someone above said, it’s when the feed changes and the cows are adjusting.
