Hi all
Very little/no water coming out of hot water or group head when I turn it on or try to pull a shot. Makes a kind of buzzing (but not rattly) noise when I press the shot button or turn the hot water dial and no nice machine hum like it should. Also intermittent water bubbling like it's trying to prime itself all the time, not just when I press the button. Also the buzzing noise happens every so often even when I haven't pressed a shot button or turned the hot water dial. Also seems to heat to beyond 93 degrees, to which it is set.
Haven't taken the cover off yet and it's probably never been descaled. Any ideas?
