Rewiring a dishwasher on 230V instead of 400V

Hello! I am moving to a new flat and my old Miele dishwasher was plugged in a three-phased 400V socket. In my new apartment I have a single phase 230V 10A socket. On the back of the dishwasher there are 3 schematics, one of which is 230V 10A.




I have two questions:
- Is it allowed to switch to 230V myself as this will be plugged in 230V? I know simple installations on 230V are allowed in Switzerland. But does this fall under three-phased 400V anyway?
- What is the meaning of SW on the black line that goes to L2 and what is the red line that goes to L3 in the schematics?



Thank you in advance!

SW = black (schwarz)

Which is always confusing for an English speaker - for us it would mean SWitch(ed); in German that's SCH(alter) which is even more confusing because that also matches the first three letters of schwarz!

You can do what you like with an appliance - the rules apply to fixed wiring.

Re: Rewiring a dishwasher on 230V instead of 400V

I think the point of the diagram is that for 230V 10A you wire the live input to L1 and L3:

- move the black wire to L3 in the appliance.
- put both black and brown into the live pin in the plug.

But I'm only about 80% confident of this, I'd be looking for a manual online for more confirmation.

Re: Rewiring a dishwasher on 230V instead of 400V

That copper bridge between what looks like Neutral and a Phase conductor looks somewhat out of place. Have you moved it ? Does the red marking on the wiring diagram appear to be the manufacturer's original marking ?

Edit
----

Studying it again, it looks like the copper bridge is in a isolated retaining slot so it does not get lost. It is no electrically connected. Also, I guess the factory delivery condition is that it was wired according to the schematic on the left. The red markings are to indicate deviations form the factory condition. I say no more.

That is the storage position, it is connecting nothing.

Re: Rewiring a dishwasher on 230V instead of 400V

As far as I understand the red line shows what has to be done to change it from 3phase/10A (actually only two phases are used) to 1phase/10A or 1phase/16A configuration.

It is currently set to 3phase/10A. As newtoswitz says you would have to switch the black wire from L2 to L3.

I'm sure that is correct. I was updating my answer as yours came in.

Re: Rewiring a dishwasher on 230V instead of 400V

I was also asking myself why the bridge was there. Now that you say it, it seems very logical that it is in storage position.

As for the red line (and the arrow that points from L2 to L3), it also seems very logical that it means if I want to go from 400V to 230V, I must rewire black (sw) from L2 to L3.

Now that raises another question, on a single phase cable I have 3 wires :

- Blue = Neutral
- Yellow/Green = Ground
- Brown (in my case) = Phase

The black wire (sw) that I must move from L2 to L3 doesn't exist. Should I put the live wire (brown) into L1 and bridge L1 with L3. Then what about the 3rd diagram, it would mean that L1 L2 and L3 are bridged if we follow the same reasoning.

Thanks again!

Re: Rewiring a dishwasher on 230V instead of 400V

I would say L3 is not connected to anything internally and just the "storage" position. From this it should become evident what the bridge in the 1phase/16A configuration does and also why L2 is connected in the 2phase/10A configuration.

Thank you very much! That sounds very plausible, I will try it tomorrow and keep you updated.
