This post is more of a thank you to all the great information and resources this group of enthusiasts provides. I don't post often, mostly because the HB forums have been able to help me and answer my questions without having to ask. So it's with my latest issue/challenge I feel compelled to share this - to "give back" a little, if you will. Now to the story....
While performing my quarterly descale, my machine tripped the GFCI it was on. Initially thought it may have been brought on by running the pump and triggering the heating element in too rapid of succession. I turned it off to cool down a bit - a good excuse to let the descaler soak and do its thing. After an hour or so, I fired her up again and 'click' - GFCI tripped again. Reset - 'click.' I knew I had a short somewhere. Time to open the box and hit the boards here.
First items on the checklist were the obvious:
Here's what I found:
This is apparently what happens when a 1350W element shorts out in a boiler full of water. All I could think of when I saw this was how fortunate I was that I had my machine on a protected circuit. If you don't already have your machine on a GFCI or otherwise protected circuit hopefully this will convince you to do so.
So, now while I sit and wait for the new parts to come I figure it would be a great time to double check the health of my boiler and do a more thorough cleaning. Hard to get a good picture, but she really doesn't look so bad. A little scale build up near the water inlet and outlets, but nothing a good overnight soak (cold - obviously) in Urnex shouldn't fix.
Again, all of this - all of the info I found on how to troubleshoot, what to test, tips and tricks on how to - came from all of you that share your knowledge and learnings through these boards. So thank you all for this lovely wealth of info and support. You're really a great lot - cheers!

First items on the checklist were the obvious:
- check for leaks - none
check my connections - all solid contact, no corrosion
check my wire insulation - good to go
- check the boiler level - it was good
check the thermal fuse - had to relearn how to use a multimeter, but continuity was good
check the resistance on the heating element - no continuity and dynamic resistance readings all over the board, starting to think it's the culprit

Nice pics . . . admirable attitude.
You should always descale this particular machine as you did . . . resting on its side.
