Thermador Topaz DWHD640JPR Dishwasher Review

The panel-ready Thermador Topaz DWHD640JPR dishwasher (MSRP $1,499) slots just beneath the $1,699 DWHD650JPR, which is part of the Sapphire series.

Functionally, the two dishwashers are identical. Both feature a third rack, excellent cleaning ability, and a 22 7/16-inch depth measurement that allows either one to be installed flush with cabinetry. Yes, the Topaz is rated at an ultra-quiet 44 dBa, while the Sapphire is an even quieter 42 dBa, but unless you're sleeping in your kitchen or have it installed on stage at Avery Fisher Hall, you probably won't notice the difference.

The only other extras you get from the Sapphire won't get your dishes any cleaner, but they will up your dishwasher's cool factor by about a million points: more fold-down tines, stainless trim on interior handles, and really attractive blue-tinged interior lighting. It's one of the best-looking dishwashers we've ever seen.

If you can do without those über-luxe touches, however, the Topaz is still a gem you’ll be happy to show off. It comes with a two year parts-and-labor warranty overall, and additional warranties on electronics and racks that last five years. And thanks to Thermador's One Two Free promotion, you might be able to pay zero dollars for the DWHD640JPR if you buy a suite of Thermador appliances.

Ready for anything

Flexibility is important in a dishwasher. Some nights, you’ve ordered takeout and you're just washing a few dinner plates and silverware. Others, you've hosted a dinner party and need to cram every pot, pan, and baking sheet you cooked with. With a compact cutlery basket, a third rack, and a multitude of foldable tines, the DWHD640JPR is ready to fit dishes big and small, short and tall.

The controls are set up in a simple, intuitive left-to-right layout. Just power on, pick your cycle, pick any options you want to add, and hit Start. The buttons light up in brilliant blue, and an LCD screen in the center of the control panel gives you an estimate of how long a cycle will take. The dishwasher is extremely quiet, so it beams a light on the floor to let you know when it’s running.

Aesthetics are also important. Luckily, the DWHD640JPR is ready to accept a custom panel, so you can be sure that it matches perfectly with the rest of your kitchen's look. It comes with a template for drilling holes into a panel for a perfect fit. The tub is uniquely designed to be capacious enough to fit lots of plate settings, but shallow enough that the dishwasher can be installed flush with cabinetry for a modern, unified look.

If you want a stainless steel finish, you can buy the DWHD640JFM with a contemporary Masterpiece handle or the DWHD640JFP with a pro-style Professional handle for the same price you.

Cleaning

Solid cleaning power

Thermador is part of BSH, the parent company that also owns Bosch and Gaggenau. All three brands of dishwashers are based on the same general design. As such, we expected this Thermador's performance to be similar to Bosch dishwashers—which is generally very good—and we weren't disappointed.

The DWHD640JPR will get your dishes clean in a reasonable amount of time. Normal and Pots & Pans both take around two hours to finish, which is what you can expect from most dishwashers. However, the Quick cycle took 1 hour and 13 minutes to complete, not quite earning its name. Unfortunately, that’s the fastest cleaning cycle on this dishwasher, so you might be out of luck if you run out of flatware during a party.

This Thermador has a few specialty options to change the way a cycle washes. Half Load causes the dishwasher to use less water and power, shaving some time off of a cycle’s duration. It's perfect for when you’re not doing a full load of dishes. Powerboost is the exact opposite: This option uses extra heat and water pressure to obliterate stains.

Most cycles reached temperatures as high as 162°F—hot enough to kill most bacteria.

Why We Like It

Upscale, but not overboard

If you've decided to buy a suite of Thermador appliances, you'll be glad to know you're getting a great dishwasher.

The Thermador Topaz DWHD640JPR is certainly upscale, but it isn't overwrought. A solid cleaning machine with just the right amount of flexibility, adjustable parts, and extra features, this Thermador doesn’t try to overwhelm you with full-color displays, dazzling interior lights, or cycles that you’ll only use once in a blue moon.

A great dishwasher doesn’t necessarily have to innovate; Sometimes, all we need is a box that cleans our dishes and fits in with the rest of the kitchen’s aesthetics.
