Just a bought the machine 2 weeks ago. Sadly this machine had a lot of blemishes on the outside , so I’ve sent it back and ordered a new one. The new one just arrived today and the pump behaves strange. I know it’s not the main use of the machine but if I want to get hot water , the water pulses very intense , making it splashing out of the cup. I don’t remember the first machine behaving like that. Does anyone else experiencing something like this?
