I am the new owner of a pair of vintage Miele's and am hoping someone can lead me in the right direction. I have a 1065 washer and T372 dryer, but am afraid the wiring in my laundry room may not be compatible for them.

I would like to hook the 1065 up to a 120v/20amp circuit if possible. Do I need a special cord?

Also, my current dryer circuit is 40am/240v, with a standard US 3-prong dryer receptacle. Is it possible to run the T372 dryer off of this?

I appreciate any help provided!

If you already have a 240 volt circuit, you can fun both the washer and the dryer off that. You'll need a splitter box or cable set up to provide two 15 amp 240 outlets for the washer and the dryer. I've seen people make these up themselves. What kind of outlet you provide would sort of depend on what is currently on the washer and dryer. You might need to rewire the plugs on those if you can't find the appropriate outlet. A splitter box is somewhat preferable because it can provide extra fuse/circuit breaker protection.

Also, the Miele washer and/or dryer may have come with 4 prong plugs. The 4th prong is for ground. Practically speaking, it's not absolutely required for the appliances to run, but it is code to have everything grounded, and safer. Lots of people (myself included) have wired these up to run off three-prong outlets, with two hots and a neutral, by using a three-prong plug and just tying back the ground wire (although it would be safer to connect that to a good ground, like a rigid conduit or cold water pipe).

If you are not comfortable with wiring such things, call Miele or an electrician.

But again, while it IS possible to wire the washer to run on 110 volts, it won't heat worth a damn and it's really not necessary if you have 240 volt service already.

never connect ground wires to pipes !

grounding is absolutely a don't do it yourself thing.
Only a skilled electrician can do it in the proper way (dispersors in a "well"). He also will check that the ground circuit resistance is low enough to let the eventual "leaking" power dissipate easily into the ground rather than through a human body .

Our electrotechnique teacher @ Uni once told us a sad story happened in the sixities. Once the daughter of the director of Italian Electrotechnics committee was having a bath in the bath-tub. She was found dead with one hand on the cold water tap and the other one on the hot water tap.

At those times cold water tap and hot water one were separate things (not like today' ones, where the 2 pipes are linked to a single tap unit).

As ground wires were linked to the cold water pipeline, there was a electric potential difference between cold and hot pipelines. That's why she was killed by electrocution

Oh, some people recommend grounding to a gas pipe instead.

The problem with grounding to water pipes occurs when there is an electrical continuity break in the water pipe. This can occur if there is a non-bonded dielectric union in the path, such as might connect a steel pipe to a copper pipe, or if there is plastic pipe connected to metal pipe.

Seeing an electrician is a good idea if one isn't sure of the specifics.

Thanks for the info. Both machines have grounded 3-prong plugs, similar in configuration to the photo below. They are both rated for 20 amps.

Is the splitter box something I can buy from my local electrical supply house and install? I am comfortable with installing a new receptacle. I don't think I know enough about working with electricity to build my own.

That looks like it could be a standard 20 amp 220 volt plug.

However, it's not "grounded", the U-shaped prong should be the neutral wire for these machines.

I don't know of any place that sells the appropriate splitter box. I got a Malber unit off eBay a while back, though, and it has outlets that seem to match those plugs.

You could try local appliance shops that sell Euro style front loaders, or an electronic store. Or search the internet.

Miele 120V Cord For Washing Machine

launderess's profile picture
Yes, one requires a special cord, which only comes from Miele USA (surprise), however they no longer import the part to North America. You can contact Miele to see if any are still in stock or lying about spare.

You will need a wiring diagram to know how to hook up a new cord converting the machine from 220v to 120v.

Miele is starting to phase out parts for the 1065/1070 units. Both machines were amoung the first offered in the United States and are nearing if not passing the 15 to 20 years Miele promises to keep parts in stock for a model. However certian parts may go on a bit longer as they are used in later models as well. Things such as the motor, timers, and so forth however are limited to whatever stock Miele USA has on it's shelves. Once these go, that will be the end of that.

Indeed it is getting harder and harder to find Miele techs willing to work on older units. Most will strongly advise a customer send the thing to the knackers yard, and purchase new. Our Miele tech certianly made strong noises in that direction when called out for our 1070, indeed told us that a customer just scrapped an old Miele washer on his recommendation and purchased new. Just as an aside, contacted the store where the new unit was purchased, and that took the old unit away, and sadly it went straight to the crushers. Apparently with space in short supply, this local appliance store does not hold carried off appliances long. Each night someone comes to haul them off.

If one has 220v service in the laundry area, simply purchase the splitter box from Miele (or search eBay, they pop up there often, and go for FAR less than what Miele USA charges), and one can run the washer and dryer off the same circuit.

Californian safety laws

Lee, really do your laws allow grounding to pipes ?

Hope you haven't such things in your plants (you said why : copper-steel matching and so on)

I believe code for new 220v circuits is that they must be four wire: two hots, a neutral, and a ground. Grounding to water pipes is frowned upon because of the possible presence of dielectric unions that are not "bonded". Bonding means a short length of bare copper wire is clamped to the pipes on either side of the union. This achieves both the goal of eliminating galvanic corrosion while at the same time ensuring electric continuity.

Plumbers don't like water pipe grounding because they might get shocked if they disconnect a cold water pipe while some defective appliance is sending current down it to ground. I've seen plumbers ask or check carefully before working on such things.

Came a little bit later than you folks, but thought of sharing my experience. I got a Miele W 1065 from Craiglist in SF a couple of days back and needed to wire it in my old apartment that doesn't have 220V.

I created a small blog post about it, in case it helps someone:
