As does the Alexia.

ok, this was interesting. One of the SSR top wires read about 17 volts and the other read 2.5....

When I trace the wire at 17 volts, I am nearly positive it goes to this:





Not sure what that is, so I haven't gone to messing with it just yet.



OK I'm trying to get this electricity stuff, but I think the past few messages went over my head. I can try to make a very rudimentary sketch of they way the wires are getting to and from the heater element terminals. I'll get to work on that. So great to get all this help gentlemen! You're willing to give so freely of your time and energy. Thank you.

That's simply a terminal block - a convenient device to make wire connections. From that pic it looks as though the SSR is RIGHT THERE. The two white wires connected to the top of the SSR - they look pretty hefty and I do not see any hefty white wires on your terminal block - maybe a small white wire at the edge.

Anytime you are tracing wires, UNPLUG the machine. When you are checking for voltage, the machine should be on and YOU SHOULD BE CAREFUL.

So, since you initially said in your first post that the autofill worked, I would hook all the wires back up (including the heating elements), post a pic or link to your multi-meter and give me a call at 301-587-5033. Troubleshooting machines via what is essentially email - gets old real fast.

For the sake of future searchers:

Problem solved! The problem was the main power switch. Though most of the terminals on it were working, the one transferring power to the boiler element was faulty. $27 and a week later, rescue arrived from the state of Washington. A quick and easy install and she was living and breathing again, even stronger than before.

Thank you again for the ceaseless help. You were all crucial in narrowing the problem down, and you helped me learn an insane amount about the inner workings of my machine. You rock.

KJM...

I have a Bunn ES-1A. The original stock switch proved faulty very quickly, and just like you, a shipment from Seattle made things work properly. If mine fails again, I plan to replace the stock style switch with a 3-way toggle switch - I just know of too many of these that haven't lasted through time.

Enjoy the Bunn - they are fun machines that also make killer espresso, IMHO.
