Chosen Solution
i have had my Barista for about 8 years and love it!!!! I have been traveling and it has been unused for about a month. I cleaned the water tray, filled it with water, then put the hose into the water, and turned the button on. The machine made its usual noises like it was working properly, i let the brew cycle run for a little bit to prep it, but when i got to the steam stage, no steam came out. so i tried to prep it again still no steam. HELP!!!!
Did water come out of the machine when you pressed the brew button? If not, you may need to force-prime the machine to get it working again. Using a turkey baster or similar tool, squeeze water up the hose while the pump is running. Once the water flows through put the hose back into the water tank and allow it to run for another 10-20 seconds to ensure the boiler is full. Then it should be ready for use.
This repair guide provides a procedure to test the Steam thermostat switch (attached to the boiler). No need to disassemble, just requires a multi-meter - Schematic and Troubleshooting Starbucks Barista SIN 006. There are very few components in the steam circuit - it will likely be either the 125 deg. thermostat or the micro switch attached to the steam valve. Opening the steam valve should turn the pump on. If not, the problem will be related to the micro-switch wiring, or possibly the cam that operates the switch when the valve is opened may have just come loose and is not turning the pump on.
The Steam function requires 2 things: The 2nd stage heater element heats the water to the higher temperatureThe Steam valve be opened and clear The heating stage is a function of the electrical elements - the switch, the thermostat, and the heater element - they must be working properly in order to heat the water. The Steam wand only requires that the Steam valve be working properly, and the wand be free of obstruction. Troubleshooting: the steam valve has a small locking screw that can become loosened and then it will fail to operate the internal valve when the knob is turned. Or the valve can become corroded internally. Either of those conditions could cause the steam to fail or not flow fully.
If you have knowledge in repairing then try the following but frist try solution from Henry First locate your steam pump most coffee machine I repaired have steam pump seperately, so you need to run the pump directly to the power it should be rated on how much voltage it works with. if the pump does not work then you need to replace it remember pump can be repaired also. If the pump works then you have problem some where else that is the driver for pump mostly electronic board. Try upto here n tell me so that i can guide you further. Ashwin
