Cuisinart Coffee Maker -- Diagram or photo of internals?

Question

I ran the clean cycle on our Cuisinart DCC-2650 coffee maker, but then when I went to rinse it with clean water it didn't heat up.

I removed the screws from the metal bottom plate, but it seems that that was a mistake, because when I removed the deep-set screws in the plastic part of the bottom and removed the whole bottom everything was disconnected from that metal plate, and I can't see exactly where everything fitted.

More precisely: there is a Q8025J6 Triac hanging by its wire leads, which are held against the edge of a clear plastic part, and an aluminum plate (heat sink) but I can't figure out exactly how they go back together.

And IAC if the Triac is the problem, so far I've only found companies selling them in minimum lots of 50.

I figured out how everything goes back together, but of course it still didn't work, so I did a little probing with the bottom (plastic plus metal plus everything attached to the metal again) off and the thing plugged in. I measured 120V across the outer shells of what I assume are thermal fuses with their leads spot-welded to the terminals of the heating element, but nothing across the terminals of the element. One of those thermal fuses is bad, but with no way of spot-welding a replacement in place is there any practical way of fixing it?

I had a coffee maker with failed thermal fuse. There were two in series and I just jumpered the bad one. This had spade type connectors... maybe post pic and someone will have an idea.

You seem to be posting via Google Groups, whereas I am posting to UseNet with no possibility of attaching pictures.

eBay has multiple listings for thermal fuses for Bunn coffee makers, but I would still have to find a way of connecting one in circuit: solder is out, so I'd have to find crimp connectors of appropriate size.

UseNet  You don't have to "attach"; put a photo anywhere on the web (Dropbox etc  etc) and include a URL... Mike.

This needs boiling water. No CPU, no Triac, no cords .

Then, eutectic silver solder.

Safe, effective, and will withstand the heat.

Use the squig (soldering ring) to join the ends and then crimp it. Solder with silver solder. Done.

I keep both for just these sorts of repairs, and also my wife's jewelry.

Yes. The retail bubble-packaged replacement thermal fuses I have seen (at, e.g., Fry's) come with small crimp rings. --  G. Paul Ziemba FreeBSD unix:  2:51PM  up 94 days,  4:19, 14 users, load averages: 1.47, 1.13, 1.03

Ah, Fry's. Unfortunately, the stores are all about three hours from here, and shipping probably would be much more than the cost of the item.

I've bought a Bunn thermal fuse "set" (two connected in "Y" configuration, but I need only one). Should be here Tuesday. I have some crimp connectors and some push-in connectors. Both with insulation rated to 105C, which should be OK.
