Title
How to Troubleshoot Starbucks Barista SIN 006
Introduction
This is a basic procedure to diagnose problems with most of the critical components of the Barista SIN006 without opening the unit:
* Switch Operation
* * Main Power
* * Pump
* * Steam Switch (Boiler)
* * Steam Valve Microswitch (Pump)
* Boiler heat coil resistance (approx. 16 Ohms)
* Pump coil resistance (varies a lot 1.6 M Ohms to open circuit - not a comprehensive test)
* Thermostat boiler switches:
* * Heat (95 deg. for espresso)
* * Steam (125 deg. for steam)
Begin with the machine unplugged, cold, all switches in the off position.

Conclusion
If the previous tests all pass, plug the machine into the wall outlet and run water through the steam valve to cool the boiler, until the Ready light goes out. Turn off the power and close the steam valve. The electrical components should be operating normally.
If there are problems with water flow, the unit should be disassembled for thorough cleaning.
