Manufacturers add features to their washing machines for a number of reasons, including to save you time and to boost convenience (not to mention the price of the appliances).

Some features are intended to solve a problem. Samsung AddWash, for instance, is designed to address one of these laundry nuisances: Adding items to a load after the wash cycle has already started. This small windowed door-within-the-door of a front-loading washer lets you toss in items after the wash cycle has begun.

“AddWash is a little useful,” says Emilio Gonzalez, the engineer who oversees Consumer Reports’ tests of washing machines and dryers. “On other front-loaders you can just pause the washer, open the door once the machine has stopped, and add laundry. With Samsung AddWash, you still pause the washer, but the small door lets you add the item slightly quicker.”

(One thing to note: The owner's manual for Samsung AddWash models states that water droplets might form on the interior of the the window. So after a load is complete, you're supposed to leave the AddWash door open to let the interior of the washing machine dry. Keeping the door on any front-loader open between loads is one way to prevent mold and mildew.)

Samsung AddWash Test Results

We tested the AddWash-equipped Samsung WF50K7500AW, $1,100, and Samsung WF45K6500AW, $1,000, front-loaders. They performed similarly in every test, delivering excellent cleaning and water and energy efficiency, and were among the gentlest on fabrics of all front-loaders we tested. They’re relatively quiet, and vibration isn’t a problem.

Both washing machines are loaded with features, including the Super Speed option. In past tests we found it saved about 15 to 20 minutes without affecting cleaning. That’s something to consider, since both washers took 100 minutes to do a load using the normal wash on the heavy-soil setting. You’ll save time using the normal-soil setting. These washing machines also offer remote control using your smartphone and the Samsung Smart Home app.

The Samsung WF50K7500AW has a claimed capacity of 5 cubic feet; the Samsung WF45K6500AW's is 4.5 cubic feet. These washers are the usual 27 inches wide but 35 inches deep, more than usual. 

Money-saving tip: We found the Samsung WF45K6500AW on sale for $700 at Best Buy, Home Depot, Lowe’s, Sears, and other retailers.

Samsung AddWash isn't the company's first attempt to freshen its washing machine line. With the Activewash on some HE top-loaders, you can soak items in the basin before they go into the washer. Not to be outdone, some LG washers have a mini-washer in the pedestal for smaller loads.
