The redesigned wash arm puts a new spin on dishwashing.

One of the greatest challenges in designing a dishwasher is figuring out how to get water to every dish, regardless of its size, shape, or location in the tub. Samsung’s WaterWall and KitchenAid’s Dynamic Wash Arm both attempted to tackle this problem by redesigning the main wash arm. LG’s recently announced MultiMotion takes a page from the same book, and we got a chance to check it out at CES 2016.
At first glance, the MultiMotion wash arm doesn't look any different from the four-bladed wash arms found in high-end dishwashers from other manufacturers. However, once it was moving, we quickly understood what MultiMotion brought to the table.
The motor-driven wash arm spins like normal and is able to reverse directions, changing the angle of the spray. That's not the new part, though. Two of the blades are stationary, but the other two can tilt, directing streams of water at varying angles instead of just straight up. This simple change in spray pattern offers better water coverage because it attacks stains from all sides—according to LG, at least.
The dishwasher section of LG’s enormous booth contained four MultiMotion-equipped models that will be released later this year. Aside from the new wash arm, all four models will contain LG’s EasyRack Plus—a system of adjustable rack features, including folding tines, fold-down shelves, and height adjustment.
These machines will also feature Smart ThinQ, an upgrade to LG's older Smart Diagnosis. It allows users to tap an NFC-enabled smartphone against a designated area of the dishwasher to quickly and conveniently grab error codes when the dishwasher is malfunctioning.
Two of the models, the LDT8798ST and the LDT5665ST, will have a protruding, gently curving handlebar with top-mounted controls. The former will have a third rack and Turbo Steam, while the latter will not.
Similarly, the LDP7786ST and LDT5545ST will both have a recessed pocket handle. The former has top-mounted controls, a third rack, and Turbo Steam, while the latter does not.
None of these dishwashers have been priced just yet, but judging from our time spent opening them and manipulating the racks and controls, they all feel like mid- to top-tier machines.
