It's actually probably a 240 volt outlet, since I don't think you can get an American power company to supply 220 volts :) But anyway, it should be more like $50 dollars to replace the outlet, but the company might have a minimum visit fee, so you could wind up paying more. On the other hand, if you have anything else that you wanted done electrically, you could probably get it done at the same time for the same price. The one problem that could make it *very* expensive if this is an older house is that you might not have a ground at that location. Some of the older houses had NEMA 10-30 outlets, which were hot-hot-neutral, no ground. You can upgrade them to NEMA 14-30 (in some situations), which is supposed to be hot-hot-nuetral-ground by tying the ground to the neutral and declaring it "safe enough." Obviously, you can't then convert it to standard three prong grounded, because there is nothing to ground to unless you can add a new ground, which might be where the extra cost comes in. That said, we are pretty happy with our Miele pair, and it fits in the space you described, but requires an additional part that doesn't come with it, and that the installer had never heard of. But as the other poster said, only the dryer takes 240. The washer takes 120 (standard american 3 prong)

The Bosch washer has a three-prong NEMA 6-15P plug that fits into a 6-15R outlet - 208 or 240 volt, 15 amp, with two horizontal slots in a row (both hot) and a round ground hole. If your Asko dryer outlet looks like the upper one in this pic (the lower outlet is the more familiar 120v), it should work. The dryer probably has a large 208/240 volt, 30 amp plug at the end of a thick cable, intended to power a large 27" or wider American electric dryer. Most of the smaller 24" wide dryers draw less than 15 amps, but are often supplied with a 30 amp plug anyway (either 3 or 4 prong, often owner swappable) with internal fusing at 15 amps because such wall outlets are common in American laundry rooms. Since the dryer draws less than 15 amps, a 240 volt/15 amp outlet on the back of the dryer allows a 240V/15A washer to plug into the dryer, and the dryer to plug into a 240V/30A outlet thus powering both machines.

I believe Speed Queen is called Huebsch or something like that in Canada. I have a SQ dryer and like it a lot, but I don't think it would fit in your space. I think you have to evaluate each brand by product. I understand GE makes a decent refrigerator, but I wouldn't recommend them for laundry equipment: poor build quality and even poorer customer service. I learned this the hard way. Whirlpool makes a fine vented dryer; my last dryer was a whirlpool. It was 11 when it went to live with another family who could make the needed repairs themselves. You probably already know that whirlpool and maytag are the same company: whirlpool. I go for functionality in my appliances. Washer and dryer are different brands and both are appliance white so they sort of "match." Good luck in your search.

We have 2 different Axxis machines and don't have a problem...I made sure to put some heavy duty rubber feet on the dryer...
