Hi,got Eletta cappuccino top machine, problem is that it not gives enough water, when I pressing "hot water" it gives me only 1/3 of cup,all pipes are clean,water pump new and water flow sensor new just replaced,when I disconnected water pipe from boiler and put pipe straight into cup it makes no difference. Can u help me ? It is main board issue? Calibration issue? Looks like machine things it gives me full cup but it is not.
