Maytag MDB7749SBM Review

The Maytag MDB7749SBM is a powerhouse of a dishwasher that's cheap to buy, pricey to run.

Introduction

The MDB7749SBM’s test data reads like the results page at the end of a Halo match. Some of us couldn’t help but giggle with glee at the high percentages of soil removed (“KTD ratio,” if you want to use gamer parlance). While the machine has one of the highest annual costs we’ve seen, there’s a great amount of satisfaction in watching it utterly obliterate the dirt stains we use in our tests. Or maybe they should let us out of the lab more.

Performance

Impressive results on Normal and Heavy cycles.

The MDB7749SBM will clean your dishes, period. On the Normal and Jet Clean cycles, this dishwasher scored in the high 90’s in every food category. This included the spinach test, a notoriously difficult test that usually leaves spinach particles behind on other dishes. Like many other machines, the lipstick test gave the MDB7749SBM a bit of trouble, but an average score hovering around 70% is very impressive for a test that many are doomed to fail.

The Quick Wash performance scores were extremely unimpressive, and the complete opposite of the results on the Normal and Jet Clean cycles. However, it soon became obvious why the results were so pitiful – the Quick Wash cycle only lasted 37 minutes! Clearly, that cycle is not meant to handle the amount of soil we threw at it, as it sacrifices most of its cleaning power to get that impressively low cycle time.

Efficiency

Forget going green.

The MDB7749SBM uses a lot of water. There’s no other way to say it. Even the blazingly fast Quick Wash cycle, clocking in at 37 minutes, used 6.4 gallons of water. The Normal cycle used only slightly more water, at 6.63 gallons, but also took nearly three hours to do its job. Finally, and expectedly, the Jet Clean cycle took the most time and water to deliver its incredible performance: three hours and 36 minutes with 12.16 gallons of water. All of this adds up to an estimated yearly cost of $47.22 to cover electricity and water usage. For reference, we have found that most of the machines we test have this figure closer to about $32/year.

Capacity

Barely gets a perfect ten.

We were able to fit ten place settings in the MDB7749SBM. As is standard with our capacity tests, this also included one serving setting. After loading that tenth place setting, the MDB7749SBM was completely crammed. There was no logical place to put even a shot glass, if we were so inclined. For capacity, this dishwasher just barely squeaks in a perfect ten score.
