So, on the picture that I posted; am I right in saying that the copper tubing terminates with a 'nut' that can be completely undone? Is it just a compression seal? Cos' that's exactly where the leak is coming from, right where the tubing enters the nut. I'm gonna search the forum and see if I can find anything related to disassembling this part and possible fixes.

leaking EM6910
Hello Frank,
Welcome to the innards of coffee machines,your Sunbeam is one I enjoy because they are so active inside!
All the copper work seen inside these are just perfect conditions for vibration and noise,don't you reckon?
Because of all this vibration ,it's not uncommon to find loose things in there that will allow water to flow more then expected.
The Brass fitting onto the steam pump is effectively brass threaded onto plastic (steam pump outlet thread) this is less common as the plastic tends to take vibration better then metal to metal does however,you still have a leak there!
I suggest you (excercise all caution with exposed hot pipes and 240 volts)remove the brass nut (both ends of copper) and clean up the mess,check the plastic outlet is sound and not cross threaded and then carefully reinstall everything again,firmly but don't over tighten.
Working carefully ,as the cabinet is still open and there lurks danger there if touched,turn things on again and observe whether the leak is resolved.
Should be the answer I reckon,good luck......unless your steam boiler is blocked,then thats another challenge,see how you go.
I would have removed the entire steam boiler and confirmed it as open and clear,plenty of experts and solutions to checking this,you probably have seem them,give them a good go,when you eventually close up the machine,hopefully everything will be good again,happy steaming with no leaking!
Cheers,
Mick.

So I took it apart and disconnected the copper piping from the steam pump. Found that the plastic thread looked Ok...but not great. Anyway, didn't waste any time - just wrapped some plumbers tape around the thread and tried to overlap a little onto the rubber washer which was definitely worn. Put it back together and...result! no leakage. Ran through a de scaling cycle and have made a few brews (not the best brews but I'm just a beginner!) with zero leaks. Pretty happy as I got the machine and grinder for $100. I've got a few pics on the link below.
You can see that the rubber is clearly worn and slightly perished. I'm not sure how long the repair will last but at least i'm a bit more familiar with the insides of the machine now. Does anyone know if it's possible to buy just the rubber, or must you buy the copper pipe plus rubbers? Are there reputable sellers on the forum for parts etc?
