The Whirlpool Duet HT WFW9400SW is a front loading washer made available by Whirlpool, fitting in the center of the mid-range Duet HT line. The ultra capacity plus stainless steel drum handles up to 16 pairs of jeans using half the water and energy of conventional top loading machines, and can handle other bulky items such as comforters or rugs. There are 14 factory pre-set wash cycles and options, including a cycle for bulky items, hand washables, delicates and wools to name a few. There is a four-tray dispenser which releases prewash, detergent, bleach and fabric softener at appropriate times in the cycle. The HT WFW9400SW is available in a "silver metallic on white" finish, while the matching dryers come in plain "white".

In order to optimize the efficiency of the wash cycle, the 6th sense technology determines the size of the load being washed and automatically determines how much water is required, while it monitors and controls the water temperature with the built-in water heater and keeps an eye on the suds level to prevent oversudsing. The direct inject wash system penetrates stains with a concentrated burst of detergent eliminating the need to pretreat stains. The add-a-garment feature indicates how long new items can be added to the cycle without affecting the wash quality. The variable-speed motor spins at a maximum 1,200 RPM and uses a 6-point suspension system to reduce vibration and noise while in operation. Other features include door lock, child lockout, audio feedback, instructional control and optional laundry tower and worksurface. The matching dryers are the WGD9400SW Duet Super Capacity Plus Gas Dryer and the WED9400SW Duet Super Capacity Plus Electric Dryer, which can be setup side-by-side or can be made stackable with the purchase of a stack kit.

We bought our Whirlpool 9400SW washer a year and a half ago. It started sounding like a 747 was landing in our laundry room. It turns out seal leaked. So the the oil ran out. It's not safe to use, as the barrel can come lose and fly out on spin. Can you imagine that? Anyway, It's too expensive to rebuild so the extended warranty company is trying to find a 'comparable' one. We usually don't buy the extended warrantly, but I"m really glad we did this time.
