Hi everyone!  I am having a bit of a problem with my Nuova Simonelli 2 group Appia Compact.  The pump pressure(the bottom half of my pressure gauge) keeps going up to about 12 or 15 even at rest.  I adjusted it back down manually a couple of times back to 3 - 5 bars at rest and 9-10 while pouring and it seemed to work fine for a couple of weeks each time.  Now it just won’t stay where it should when adjusted anymore.  A friend of mine suggested it might be that the solenoid valve went bad but I certainly don’t know.  Any suggestions or ideas would be greatly appreciated.  Thanks so much!
