Why Buy?
Four-arm QuadWash cleaning for a freestanding dishwasher that keeps pace with real kitchens
Four spray arms work top and bottom simultaneously, reaching cutlery baskets, tall glassware and baked-on cookware in the same cycle, so this freestanding dishwasher clears a full 15-place load without a second run.
The Direct Drive Motor uses fewer moving parts than a conventional pump, which translates to quieter cycles you can run during the day and steadier long-term reliability. Dual Zone Wash varies spray intensity between racks, so delicate glassware sits under a gentler stream up top while the lower rack takes on stubborn pans at full pressure. The upper rack shifts across three height positions, giving you the clearance for stemware one day and stockpots the next, rather than forcing a compromise load after load.
Finished in platinum steel with a restrained control panel, it reads as understated rather than showy, sitting comfortably in kitchens that mix stainless with timber or stone. ThinQ connectivity lets you check cycle progress or run diagnostics from a phone, useful when you are juggling a household routine rather than standing over the machine. At 600mm wide, it drops into a standard freestanding position without cabinetry changes.
Buy this if…
- You want one of the better dishwashers for mixed loads of glassware and heavy cookware
- You need a freestanding dishwasher that installs without built-in joinery
- You wash large loads and want genuine 15-place capacity in one cycle
- You value quieter operation for daytime or open-plan use
- You want remote diagnostics and cycle control through ThinQ
