Well it started working after leaving it at 3 for about 20 minutes. Today it did the same thing, didnt start working with the pressure set at 2 so I have left it at 3 until it starts. Is this something that happens regularly during the breaking in period and goes away after a while or is something wrong ? It is a bit annoying as I would have to manually start it each day instead of leaving it up to my solenoid.
