The odd thing about what you describe is that the brew boiler should not go on until the steam boiler is up to pressure. So based on this it sounds like the pressurestat is stuck in is "normally Open" position.
To test this unplug the machine and pull all the wires off the pressurestat (remember how they are hooked up). If you had the old style pressure stat I would say: Check continuity between the top connection on the pressurestat and the bottom connection: Should be open Then check continuity between the top connection and the middle connection: Should be closed. On your pressure stat find the terminals that are the common, normally open (NO) and normally closed (NC) and do the same test. If you don't get these readings I would go with a new pessurestat.
