Features

Generally, the more you spend, the more features you can expect. But some aren't worth the extra expense. Here are the dishwasher features to consider.

Adjustable racks and loading aids

Racks that adjust up or down, adjustable and removable tines, and silverware and stemware holders let you reconfigure the interior and organize the contents. Those devices increase flexibility, especially when you cook for a crowd, and they can help accommodate large and oddly shaped items.

Dirt Sensor

It adjusts water use and cycle length to soil level. A dirt sensor can improve efficiency, but not all work well.

Rinse/hold cycle

It lets you rinse dirty dishes before you're ready to start a full cycle. This cycle reduces odors and prevents soil from setting while you accumulate enough dirty dishes for a full load.

Filters

These keep wash water free of food that could be redeposited on clean dishes. There are two types: self-cleaning and manual. Most filters are self-cleaning; a grinder pulverizes the debris and flushes it down the drain. That's convenient but noisy. Some pricey models have a filter without a grinder. It's quieter, but it needs periodic cleaning (usually every few weeks), a job that takes a few minutes. It's your choice.

Special wash cycles

Most dishwashers come with at least three cycles: light, normal, and heavy (pots and pans). Some offer pot-scrubber, soak/scrub, steam clean, china/crystal, or sanitizing cycles as well. The three basic cycles should be enough for most chores--even for baked-on food. A sanitizing option that raises water temperature above the typical 140° F doesn't necessarily clean better.

Stainless-steel tub

Steel is more durable than plastic, but models with a plastic tub tend to cost far less. While light-colored plastic might become discolored, gray-speckled plastic should resist staining. Even a plastic tub should last longer than most people keep a dishwasher.

Hidden touchpad controls

Controls mounted along the top edge of the door are strictly a styling touch. They're hidden when the door is closed. You can't see cycle progress at a glance. (Partially hidden controls are a good compromise. They show that the machine is running and often display remaining cycle time.)
