The S1 Cafe - Helping Your Espresso Dreams Become Reality

Hi all,

I bought a used S1 V1 with the front panel LED issue. The machine is set for 15amp and heats up fine. The issue that I am having is with the LEDs on the front panel, even though the machine powers on, the power LED light is off and when it comes time for the steam boiler to heat up, the LED is off as well. Is this an indication of a bad controller board?

I did buy new LED bulbs from Amazon to troubleshoot. Connecting the new LED bulb to the back off the front control panel on both the On/Stby and Boiler did not make a difference.

Any assistance you could provide on the next steps to troubleshoot is greatly appreciated.

TIA,
Anthony

You may need a new front panel assembly or else you may have some broken wires in the cable that connects between the controller board and the front panel. By all means check the cable first since it is easier and cheaper to replace, if that's where the problem is.

BTW: Did you press the Boiler button first to ensure that it is on? (If the steam boiler is heating just fine this is probably not the issue.)

Thank you so much, Chas! Would you happen to know where I can find this ribbon cable? I will try to test this cable this weekend when I am home from school.

I did press the Boiler button but due to not being able to tell from the LED light, I did not know if they button was functioning correctly. However, I know the boiler is heating up fine.

Short of contacting Chris Coffee Services in order to purchase the exactly correct cable for the machine, you can check Walmart on-line, Google ribbon cables, or buy some ribbon cable and connectors and make your own. Since I have a Dream I can't check for you since my machine design is different.

BTW: If the Boiler is working, the Boiler Button is probably OK, too.

In case you haven't searched the site for "Ribbon Cable", I did find the following info:

Pins 13 and Pin 15 are connected together and
Pins 14 and Pin 16 are also connected together.
