Product review (1 stars): Great @ 3 Months, Not Great @ 14 Months.
Obviously the 1 and 2 year reviews are more important, but at 3 months it's going strong and we like this dishwasher. (Added 14 & 16 mo update below.) This review is of the MDB7749SBM model we received Feb 2013. Note that Maytag rapidly changes the model number of this machine. Last I looked, it's now the MDB6949SDM (circa Sept 2014).

Installed the machine myself, was straightforward, no leaks (after a month of checking), good instructions on how to install. All hookups were reasonably easy to reach toward the front of the machine. The insulation around the machine is voluminous! Especially behind the apron. Which makes for an exceedingly quiet machine. Cleaning power is impressive. The instructions "persuaded" us to start using a liquid rinse product. The combination of the new powerful machine with the liquid rinse product means we're seeing the cleanest dishes and glasses we've ever had...by a large margin. In sum: quiet, powerful, clean, attractive. Now let's just hope it's long-lasting, too.

Update, 14 months after install: Had my first "event" with the washer; it would not allow me to select normal wash. A high end machine shouldn't have electrical connection problems within 14 months, just 2 months after the warranty expires.

Update, 16 months: the controls simply stopped working. I've been reading that there is a known corrosion issue with the ribbon cable behind the control panel. The problem is called "Silver Migration," there was a denial of it by Maytag/Whirlpool, and subsequently a class action lawsuit (settled out of court) in Calif. by attorneys Eppsteiner & Fiorica of San Diego. Search this machine on Maytag's website and find the feedback titled "Touchpad Ribbon Cable Repeatedly Fails." When the repairman pulled apart our machine, he found a similarly "burned" looking touchpad ribbon cable, that was "burned" in exactly the same position as the photos shown on Maytag's website under the review referred to. Maytag/Whirlpool has set up a special phone number to deal with this problem: 1-866-931-7384.
