I picked up a La Marzocco ( SB70/2003 model) at an auction. I took it to the local repair guy. He says it needs a pump, de limes, CPU, portafilters, heaters, or about 2000.00 in parts and 2500 in labors. So I think I will tickle it.
Are there any problem parts that should be replaced because I am in there and do not care to take it apart again, maybe a switch, control pad or ?
Are there mods that improve the performance? Parts suppliers and with great prices and super service?
I have overhaul car engines and did all kinds of work on cars. Has anyone jumped in to an overhaul of an espresso machine with good result? Is there a factory or other repair manual?
I am nuts?
Call an electrician for assistance to save time and fingers.
220V : Determine if you have single phase or 3-phase 110 voltage at main breaker box.
Find an unused 40 Amp breaker. Run three wires to an outlet. Green wire / bare copper wire is ground. The other two wires supply 110 volts each for a total of 220V. Be sure to test the outlet with a Fluke meter before plugging in your beautiful machine.
Let me know if you need mechanical parts.

Chances are good that your dryer or stove will be at least the appropriate amperage.
My guess is that you weren't heading in the direction of fishing wire and adding a new branch circuit to your panel. If you do, please be careful, use the correct gage of wire, and follow all applicable local codes and best residential wiring practices. I like to pull 4 wire, since the only 208-240V device I know of that doesn't use a neutral is an espresso machine and this increases future usability of that outlet.
I usually spec a NEMA L6-30 receptacle for new construction. As Mr Mills indicated, this receptacle uses 2 different 110V hot legs and a ground - no neutral. No need to worry about phase.
If you're plugging in to the stove or dryer's outlet, no need to switch out receptacles - just go buy whatever plug matches the existing (assuming it's for 30A or higher). Hook it up your machine's power cord, connecting the 2 brass screws to the 2 hot wires and the ground (probably green) to the ground wire. Leave the silver screw (neutral) open, since you will have run out of wires at this point. If you have any doubt where things go, poke your voltmeter's probes in to the receptacle to verify.
