washer plugs into dryer, but amps on plugs don't match
 
I just bought a Blomberg DV 16540 dryer. It plugs into a 240 outlet. My breaker box has duplex 20-amp breakers on this circuit, so the total amps should be 40.

I have an Asko 10505 washer that needs to plug into the dryer. Both washer & dryer are 208/240v.

Unfortunately, the washer has a 20-amp plug, but the dryer has only a 15-amp receptacle on its junction box for plugging in a washer.

I'm wondering if I can change the junction box to a 20-amp one. (I assume I'd have to change the junction box, not just the plug.)

I can't find max amps on the specs, but specs on the dryer say max 2400 watts; on the washer, max 2060 watts. (Dryer has a 15-amp fuse, if that helps.)

Also, the washer says it needs a "240 V, 50 Hz single-phase" supply. The dryer says "208-240V ~ 60 Hz". Is the difference in Hz a problem?

I'm also trying to contact the dryer manufacturer.

Thanks!

Even though it's a double pole breaker you don't double the 20 amps.

OK, but I still need an answer to the main question.

Maybe some pictures would help us help you.

Since I obviously don't know what I'm talking about, I just took photos to post--then saw your message!

This is the outlet on the dryer, and plug from the washer.

Need anything else?

Just in case... here's the dryer plug (plugs into the wall, this one matches up fine) & the circuit breaker.

The dryer should be a 30A circuit wired with #10. 10/3 w/g to be exact. Especially since the dryer is designed to also carry the load of the washer.
Is that washer designed for the US? YES, the incorrect cycles will make a difference.

And here's a pic of the junction box on back of dryer.

Now here's something that confuses me. On the washer that goes with this Blomberg dryer (which we did NOT buy), it says the following:
Electrical supply voltage must conform to the voltage specifications (208-240V, 60Hz) located on the
appliance. For this purpose, a junction box (as seen in picture
below) must be obtained. Junction box is supplied with Blomberg Clothes Dryer (model no: DV16540 NBL00) and it works as a voltage converter from 110/120V to 208/240V between the mains and appliance.

But the outlet on this junction box appears to be for a 240 plug (see 1st photo).

It's an import, so not designed for the US, but sold here for the US market.

Unfortunately, I can't fit a regular US dryer into the space, and I thought this one would work better with the imported washer.

I was afraid you were going to say that!

Well, it is good to see in the past pic that there are fuses (or small breakers) inside the unit for the piggyback receptacle.
Since that receptacle is 15A you CANNOT plug that 20A washer into it. And do NOT replace the 15A receptacle with a 20A. The wiring and overloads in the dryer are not designed for it.

IMO you are not going to be able to use that washer with that dryer. You'll need the proper circuit run for the washer.

OK, bad news, but we'll find an electrician. I appreciate your help! :thumbsup:

One more question: if we put the washer & dryer on separate circuits, we don't need 30A, right?

In fact, could we use one of the 20A circuits for the washer, and one for the dryer?

but since you tell us that washer only takes 2060w it is less than 10 amps.
You could replace plug on washer for a 15A model since load is a lot less than 15 amps.

I copied this from the manual. It says the dryer only needs a 15A breaker.
