Re: Brand new Neff – but not been used for a few years – lea
A bit of googling found that these symptoms are due to a duff flow meter (impeller jug?). The machine doesn’t know how much water has come in.
Closer inspection of this revealed a piece of plastic jammed inside the flow meter, so problem solved!
There’s a youtube video showing replacement of the flow meter and I was able to fish out the bit of plastic with some wire. Once clear the impeller in the flow meter should spin fast and whistle (like a party blower!) when you blow down it.
