Depends on the size/configuration. My previous place was so big (and had storage heaters) that different parts of it were on different phases.

Your old machine never had three phase, or two phase, just different terminals for the supply.

Never heard of two phase stuff though - 3 phase or single..............interesting.....maybe the heating elements and motor need to be on different phases due to high current draw?

Just replaced the washing machine which came with the house. It was running on 2-phase!

The previous owner left his wife and had her plugged into the mains?

How unusual.

How does that work then? I understand a three-phase motor from three-phase power, but two-phase motor from three-phase power?

You stink, by the way. Hurry up and get your clothes washed.

Now, I've a washing machine with the traditional one-phase approach. I've connect the live to one of the live wires in the junction box, one to neutral, one to earth. And all is ok.

I'm just confused about my old washing machine. With three phase, the three "live" wires are equally out of phase. I can't get my head round how drawing power from two live wires helps. The waveform would not be regular.

Though I've read somewhere that there's a technology that uses one of the lives to drive the motor, and the other to be the brake.

A transformer will be needed...

It's all in the combination of the poles...
