I just bought a LG a/c window unit, Great! not really. I have my house wired with 120v and the a/c if for 230/208 (wherever that means). What I should do to change the voltage? is it possible in a residencial area?
IT IS JUST A VOLTAGES SO IF YOU HAVE THIS PROBLEM UNTIL NOW AND THIS M/C OPERATE IN ONLY 1 PHASE SO IT WILL TAKE ELECTRICITY FROM PHASE TO PHASE AND IT WILL BE 208 V IT IS ENOUGH TO OPERATE >
IT IS GOOD JOB IN EGYPT

If the pump is only getting 50v of power, then the power board may have a bad resistor and the board will need to be replaced. This is an older machine, so it may be hard to find a new one. Refurbs are never a good idea, so you may end up purchasing a new machine in this case.
If its been changed to 220V plugging it into 120V won't damage anything, it just won't work. Replace the plug with a 120V plug end and plug it in. If it works its120 if it doesn't, its either a 220V setup, or you have a blown fuse in the unit/power supply or some other defect.
This particular pump comes in two varieties: 220/230V for the European market and 110/120V for the North American market. The former is relatively easy to find. Several web sites have it in stock. You can also get it on ebay. The 110/120V pump is hard to find as it is a discontinued product. You can, however fix the pump if the problem is scale, which is most often the case. If the bobbin of the pump is still OK, which can be checked with a meter, you can use the old bobbin and put it in a new pump. I will elaborate on both fixing the pump if there is more interest.
You did not list your location so I have to ask are you in a 230V region or a 115 V region? This is a Russel Hobbs unit and the majority of them are 230V units.
Check the input power requirements on the actual toaster. It should either be imprinted on a label or somewhere on the bottom of the unit. If it is 230V and it is plugged into 115V your going to get the exact symptom you described. (i.e a nice hand warmer)
Also if the power requirements and the plug it is attached to are correct then try moving it to another power circuit in another room just to see if you get the same low heat result.
Hello tonyludlow1, I can speak from personal experience with 3 phase. I built a 220v 3phase converter to run my 3 phase commercial table saw. I do not believe you will have success running a 310v 3 phase coffee unit. It is likely that the heating elements are set for 310v, and if you run it on 220v domestic wiring your heating elements would not heat optimally. If it could be done, you would need to rewire the electrics in the coffee unit to 220v. Sorry to be a downer. Positive feedback appreciated. Kind regards, NormanZ :o)
It should work OK The US system is 240V single phase (split) into two 120v branches. Aussi system is hot on both sides, with a center ground (a virtual ground system) Connect the 2 main wires (usually brown and blue) to the 240 (black and red), and connect the grounds (Green/yellow to green), and leave the neutral wire off.
