Well, our machine has worked fine since it first arrived. Now, last couple of days it have been loosing pressure suddenly and everything seems right but the fact it get loose that often is starting to scare us all. There is enough water at the tank, it is normally plugged and it gets rinsed often. What can be happening? Because there is no weird noise coming ot of it. After we run some water from the group head the pressure starts to build up until it falls once again, and keeps doing it

Under typical operating conditions, it is perfectly normal for the steam pressure gauge on a machine of this design to rise and fall in a regular pattern. This occurs as a direct result of the boiler being heated up to the point where the steam pressure flips the pressurestat off (which operates like a thermostat in a sense for the water in the boiler) and then cooling back down to the point where the steam pressure drops low enough to switch the pressurestat on again. The speed at which this occurs will vary from one machine to another. Additionally, heat exchanger machines heat their brewing circuit's water by pulling heat from the water that is steaming--As the machine pushes cool or cold water through the boiler to be heated, it will see a drop in temperature and a matched drop in steam pressure, to the point where the machine may start re-heating the boiler (and rebuilding pressure). Basically, It's nothing to worry about under normal circumstances! I hope this helps. 11-01-13 05:34PM
