I am about to complete repairs and reassemble my V2. Here's what I found. First the good news. The motor and pump are still pristine after 25months. A number of your have pulled off your rotary pumps for inspection and I don't remember any of you mentioning that you had to pull the motor to get at the pump. In my case the collar that holds the pump and motor together is held on by a Phillips screw which was pointing up. Between all the wires in the way and not having a screwdriver with a shaft long enough, I could not get to it. Therefore, I had to disconnect both water lines from the pump, remove the bolts holding in the pump from the bottom side of the chassis, and then slide the pump and motor out the back. Sounds like a pain but it probably only took 5-10 minutes. When I put it back in I plan to rotate that collar 180 degrees. Then I should be able to remove the screw holding the collar on easily through one of the holes in the bottom of the chassis for future inspections.
Before pulling the pump I had checked the capacitor on top of the pump and thought it tightly connected. However, when I pulled the pump out, the bolt was very loose and the cap was flopping around. I suppose it had just been wedged between wires and other components making me think it was tight. So I am guessing that this was responsible for the slight rattling noise that had developed in the last few months.

I did find two parts I need to replace. The dripping steam wand was due to a smashed "O" ring. IN the photo below you can see that the "O" ring is still round on one side but smashed flat on the other.
About 6 months back, I smelled a burnt insulation smell coming out of my V2 and traced it to the large black power wire connecting to one side of the steam boiler heater element. Not only was the insulation melted but the wire looked very brittle just adjacent to the spade terminal. The black plastic cover that snaps over this fitting was also a little "melty" looking. I cut off the bad part of this short wire and put a new crimp connector on.
This time that wire had burnt again in the exact same spot as you can see in the photo below. Since installing the new crimp connector last summer I purchased a bag of better grade crimp connectors, so I am about to make a new jumper wire with a new piece of wire and new crimp connectors on each end. We'll see if this creates a more reliable and long-term fix.

Other than those things all looked fine. I just used compressed air and a sponge to do some minor cleanup.
