My nuova simonelli machine does not froth very good and it occasionlly makes a loud noise. i have checked the pressure and it is good for a while but about 30 to 45 seconds later it goes down, i dont see any leaks and suggestions on what can fix these problems

SOURCE: Nuova Simonelli Premier

Could be a couple of things. You will know if the pressure is bouncing around by watching your gauges. You want to pull between 9-10 bars when pulling a shot. The programming issue could be the fact that if it is used it could have what I like to call
a touchy brain board. Those do have to replaced every so often depending on how much use the machine gets. You can reprogram whenever shots start pulling bad until you have no choice but to replace the brain board. They are cashy. To program: push the stop and pitcher button at the same time and all lights will start flashing on that head. Have your grind set, use a lined shot glass and measuure your shots according to short or long, watching the flow, crema etc. The ultimate shots pull between 25 and 28 seconds.
Hope this helps.

First check the reset thermostat on the right side of the boiler below the level probe, make sure there is water in the boiler before resetting.
