LG's WM3987 is the only full-size (27"w) combo W/D sold in the U.S.; fortunately it's a good one, (4.2 cu.ft. capacity, 1200 RPM spin, heats water up to 158F, has separate prewash/main wash/fabric softener/bleach dispensers). Several manufacturers sell shallower 24"w washer/dryers, but LG's WM3455 is probably the best, although it's rather pricey. It has 2.7 cu.ft. capacity, 1300 rpm spin, heats water to 158F, though lacks a separate bleach compartment. Looks to have a big door opening for a compact washer, though I haven't seen one IRL.

Both of these run on 120V/15A, which means slow water heating and even slower drying, but also that it will plug into your apartment's nearby outlet if it isn't wired for 240V and may be advantageous if you're not allowed to add a 240V circuit.

Fagor's FAS 3612 is a considerably less expensive choice, and faster because it runs on 240v power.

Asko seems to have dropped their combo W/D, and the Eurotech clone thereof isn't sold anymore either. These had a poor rep for reliability anyway; they were made by a different branch of the company than other Asko laundry machines.

Avoid anything that doesn't heat the wash water.

Thanks so much for the info. It's sad that the options for washer/dryer combos have gotten less rather than more choice. However, I was most interested in one of the two LG's anyway so it was REALLY encouraging to hear that they are pretty good. As I said, I had an equator before but it died and service was impossible so I'm a little leery of smaller, unknown brands. I haven't been able to get in to measure yet, but I'm really hoping the larger LG will fit. The price seems better for what you get and the idea of a large drum would be wonderful. Keeping fingers crossed...

Thanks again for the info!
