Man, it's been a LONG time since I've been on here but I managed to royally kill my 1st gen Duetto. Maybe someone out there can help me with this?
The simple answer is that I need a new temperature sensor for the brew boiler. I thought it was like the other boiler and I pulled on it with pliers. Snapped the wire in two.
Why was I doing that? Because I was an idiot and dropped a socket from a wrench in there when I was removing the inner lid. It landed PERFECTLY to cause a short right at the PID controller box. After I rest the GFI/circuit breaker, the machine heated up to over 260º F on the brew side and massive amounts of steam emerged when I activated the pump. After resetting the PID I got an A2 error code which I thought was a short in the temp sensor. That's why I thought I could just pull that out, clean it, and reinsert. Boy was I wrong. I tried to reconnect the wires as best I could, but I got the A1 error basically telling me that something was not connected. Wishful thinking.
In the past, every "crisis" repair has turned out to be pretty simple and inexpensive. But I'm always nervous. Anyone know where I can get a new temp sensor and how much it'll cost? Could that short have killed the PID entirely? I'll try to call Chris' tomorrow but I couldn't find the part on their website.
Almost 10 years of making espresso very well may be grinding to a halt. Trying not to boil over on this one. Hopefully it'll pull through for another shot at (oh forget it, these puns are going nowhere)
