I haven't run it. I poured some water down the hose and it leaked. So I pored more down the pipe at the sink and it didn't leak. I just rotated it with my fingers, which might not be good either (?) but water was running through it.

I am being very careful about my tests. The circuit on the element is incomplete until I know there is water in the boiler. I won't turn on the machine until I know the pump is watered etc.

Turning with your fingers won't hurt it Nathan, you're just 'priming' the pump that way. Not sayin' you're not/weren't careful..

The motor turning the pump at speed (not primed), & with a tube attached & into a water bottle underneath/below the machine waiting for it to pull the water to the graphite chamber (liner) & graphite sweeper vanes will though., unless the water somehow make it there within 30 - 60 seconds.., but priming fist will alleviate that. {;-)

Okay, so it sounds like I need to basically attach the pump hoses. Hand twist the pump and put water in, and then screw it into the motor? Or can I just drop water down the hose as I hold it above my head?

To be honest I'm so nervous that this won't work at all that I can only muster 5 minutes of work on it every few days. When the pump leaked I cleaned up and walked away. And hour later I removed it and tried at the sink. That was 5 days ago that it had the appearance it was okay ... maybe this weekend ;-)

You can't test the pump without doing so.

Hand twist the pump and put water in, and then screw it into the motor? Or can I just drop water down the hose as I hold it above my head?

Yes, you can just hold the water inlet tube (on the machine, possibly a braided SS flexible line) above the height of the motor to prime. If you have a Pyrex or small container with a spout (your milk steaming pitcher), turkey baster, etc. What you don't want is a big length of the (clear inlet tubing is good) with any air pocket/cavity in it. That will make the pumps internals (the graphite chamber (liner) & graphite sweeper vanes area/interface) cavitate & starve for water. It may or may not do that, depending on the internal condition of your pump. It should just pull past any air pockets & discharge them, & you'll have a steady stream of water in a few seconds.

Then put the end of the hose into a suitable container of water (at table level or higher than the pump) to assist in the initial priming & evacuation of air bubbles. A pump in good condition though can pull water from a 2, 5 gallon jug below the machine no problem. The pumps can pull from something like up to a 6 foot height.

You could just attach a clear plastic tubing to the pumps output fitting to let the water just run into the sink, or a bucket.

CraigA,
Thank you for the information and help. The leak I was getting was about 2 drops per second. It did not appear to be proportional to the water pressure coming in to it. Now, just as Nathan experienced with his S27 pump, the pump on my machine has re-sealed itself and it is no longer leaking. I thought of suspected this would happen based on the initial leak drop rate.

Again thanks to both you and Nathan.

Crap, I finally tested my pump. It pumped 10 liters or more perfectly well while not connected to the machine. But then when I hooked it up to the machine water started blowing out the bottom! Looks like it's shot I suppose. I guess I can't rebuild it, so I suppose JCBeverage is my best bet.

Why is that? You said earlier in the thread: "Anyone know where a cheap replacement can be had?"

Why would you deal with a US company & all of the accociated duties, taxes, hassles, etc?, when I gave you a Canadian source (Simgo, & my 2nd post in the thread) for the cheapest price ever?? {:-|

Oh that's right! hah, forgot. Actually it's moot now. I have got it working! It was just the end cap on the pump. I though it was decorative, but the cap hold an o-ring that appears to seal at least one hole. So I at this point do not need it! I haven't gotten around to it yet, but I've flushed a lot of water through the pump, and now the machine. I'm not 100% sure what's going on with the boiler though, the fill sensor appears to work but the "tank empty" light just doesn't go off. Strange.
