Hi all, brand new here. I just picked up a used Francis Francis X1 in a thrift store for twenty bucks. It's in beautiful condition, but it pops GFI as soon as it's plugged in (regardless of on/off switch position).
I opened it up and found a dried up leak around the pump and one corner of the boiler housing. It looks like the connection coming out of the pump is the source of the leak, there's dried calcium around the join of those plastic tubes.
I thought the problem would be the heating element, everything I've read says that's the likely cause of blown GFI. But measuring resistance across the two heating connectors I get 13 ohms, and everything I've found says ~15 is normal. So that actually seemed ok. But if I leave the boiler disconnected I can plug the machine in and the GFI doesn't blow. Reconnect the wires to the boiler and the GFI pops. Here are some photos:
I also noticed a little bit of corrosion around that brass nut in the center of the boiler housing:
Any idea on next steps? Or tricks on cleaning up that corroded, dried up leaky area? I opened this up before ordering a new heating element because I expected to see zero ohms across those boiler lugs, but now I'm questioning whether that's the problem. But the system only pops GFI with the boiler connected. I also checked from each heater lug to ground, and get ~1.5M for each.
Oh, and if there's a good place to order replacement heating elements for these things, do let me know. Thank you guys!
