Getting the Most From Your Dishwasher

How a Dishwasher Actually Cleans

Understanding the basics makes every other tip click into place. A dishwasher does not scrub. It sprays hot, soapy water at your dishes from spinning arms, then rinses and dries.

This is why loading matters so much. If a big pot blocks the spray arm, everything behind it comes out dirty. The water can only clean what it can reach. Keep the path clear and the machine does the rest.

• It fills with a small amount of water at the bottom
• A pump pushes that water through spinning spray arms
• Hot water and detergent blast food off the dishes
• Dirty water drains away and clean water rinses
• Heat or a fan dries the dishes at the end

Loading It Right

Good loading is the single biggest thing you can do for clean dishes. There is a logic to it, and once you see it you will never go back to just cramming things in.

• Bottom rack: plates, bowls, pots, and pans, facing the center
• Top rack: cups, glasses, and mugs, turned upside down
• Angle everything so water drains off, not into a puddle
• Leave space between items so water reaches every surface

Which Cycle to Pick

That row of buttons can be confusing, but most days you only need one. Matching the cycle to the load saves time, water, and energy, and gives you cleaner dishes.

For most loads, Normal or Auto is the right choice. Reach for Heavy only when dishes are truly caked on. The quick cycle is not a deep clean, so save it for dishes that are barely dirty.

Detergent Types and Rinse Aid

The right soap in the right amount makes a real difference. Too little leaves food behind, and too much leaves a film. Here is how to get it right.

Rinse aid is the secret to spot-free, dry dishes, especially glasses. It helps water sheet off instead of leaving drops that dry into spots. Fill the rinse aid compartment and it doses itself for many loads.

• Pods and packs: pre-measured and easy, just drop one in
• Gel: pours easily but is generally the weakest cleaner
• Powder: lets you use less for small loads, and is inexpensive

The Pre-Rinse Myth, and Others

Many of us were taught to rinse every dish spotless before loading. With today's machines and detergents, that is usually a waste of water and effort.

Smart and Connected Features

Newer dishwashers can connect to your phone. These extras are genuinely handy for a busy household, and, as always, they are optional on top of a machine that already works.

None of this is required to wash dishes. If you never connect it, the machine runs perfectly on its own buttons. The smart parts simply save you a trip to the kitchen to check if it is done.

• Send a done alert to your phone when the cycle finishes
• Let you start or delay the wash from another room
• Warn you if the rinse aid or detergent is running low
• Reorder detergent automatically when you are almost out
• Help find the reason for an error without a service call

Hard Water and Spots

If your glasses come out cloudy or covered in white spots, hard water is usually the culprit. Hard water is water with extra minerals in it, and it is very common.

There is a difference between spots that wipe away and a permanent cloudiness etched into the glass. Spots are fixable with rinse aid and the right detergent. Etching is permanent, so if you see it starting, ease up on detergent and heat.

• Use rinse aid, and do not let the compartment run empty
• Try a detergent made for hard water if spots persist
• Run an empty cycle with a dishwasher cleaner now and then
• For cloudy glass that wipes clear, that is film, not damage

Everyday Habits for Spotless Dishes

The people with the cleanest dishes are not lucky. They just have a few small routines that take seconds and pay off every load.

Running the sink's hot water first means the dishwasher starts with hot water instead of the cold that was sitting in the pipe. It is a tiny habit that improves cleaning and drying right away.

• Scrape plates before loading, but skip the full rinse
• Load so the spray arms spin freely and reach everything
• Keep the rinse aid topped up for spot-free glasses
• Run hot water at the sink for a moment before starting
• Wipe the door edge and gasket clean every week or so

Safety First

A dishwasher is safe when treated with a little care. It uses very hot water, electricity, and detergents that must be kept away from the wrong hands. This page keeps everyone in the home safe.

• The water inside gets scalding hot, so let a cycle finish before opening
• Steam escapes when you open the door at the end, so stand back a moment
• Wipe up any water on the floor right away to prevent slips

Cleaning the Filter and Interior

The one part of a dishwasher people forget is the filter at the bottom. A clogged filter is the most common reason for dirty dishes and bad smells, and cleaning it takes just a minute.

Do this every week or two, more often if you cook a lot. While you are there, wipe the bottom, the door edges, and the rubber seal. That is where gunk hides and smells begin.

• Find the round filter in the floor of the dishwasher
• Twist and lift it out, usually by hand with no tools
• Rinse it under the tap and brush off any trapped food
• Drop it back in and twist to lock it, and you are done

Smells and Mold

A dishwasher that smells is almost always telling you something simple: food is trapped somewhere, or moisture is sitting still. Both are easy to fix.

Leaving the door open a crack after a load lets the inside dry out, which stops mold and musty smells before they start. A closed, damp machine is where odors are born.

• Clean the filter first, as that is the usual cause
• Wipe the rubber door seal, where mold likes to grow
• Check the spray arm holes for bits of food and clear them
• Run a hot cleaning cycle with vinegar or a cleaner

Troubleshooting: Not Draining

If you open the door and find a pool of water in the bottom, the dishwasher is not draining. This is common and often something you can fix yourself in a few minutes.

A little clean water in the bottom after a cycle is normal on some machines. A full pool of dirty water is not. Start with the filter, because that solves most drain problems on the spot.

• Clean the filter, as a clog is the number one cause
• Look for food or a stray item blocking the drain area
• Check that the sink drain and disposal are not backed up
• Make sure the drain hose behind it is not kinked

Troubleshooting: Not Cleaning Well

When dishes come out with food still on them, it is rarely a broken machine. It is usually one of a few fixable things, and you can work through them in order.

Nine times out of ten, the answer is loading or a dirty filter. Fix those two and dishes come out clean again. Only after that would I suspect the machine itself.

• Are you overloading it, so water cannot reach every dish?
• Can the spray arms spin freely, or is a tall item blocking them?
• Is the filter clean, or is it clogged with old food?
• Are the spray arm holes clear of food and mineral buildup?
• Is the water coming in hot enough, and is there enough detergent?

Leaks and When to Shut the Water

A leaking dishwasher needs attention, but it need not be a disaster if you know one thing ahead of time: where to turn off the water. Learn that now, while all is calm.

Take a moment today to find the shutoff valve under your kitchen sink and make sure it turns. In a leak, those few seconds of knowing where it is can save your floors and cabinets.

• Stop the cycle and turn the dishwasher off
• Turn off the water shutoff valve, usually under the sink
• Mop up water quickly so it does not reach the electrical
• Check the door seal, which is the most common leak spot

Energy and Water Savings

A modern dishwasher usually uses less water than washing the same dishes by hand. A few habits stretch that saving even further and keep your bills down.

Letting dishes air dry, by cracking the door open at the end, cuts a real chunk of the energy a dishwasher uses. Rinse aid helps them dry faster without the heater doing the work.

• Run only full loads, not half-empty ones
• Use the Eco or energy-saving cycle when you are not in a hurry
• Skip the heated dry and let dishes air dry instead
• Scrape instead of rinsing, to save water at the sink
• Run it at off-peak times if your power costs less then

Buying or Replacing Without Overpaying

If your dishwasher is on its last legs, a little planning keeps you from overpaying for features you will never use. The best machine is the one that fits your kitchen and your habits.

• Quiet operation, measured in a low sound rating, if it is near living space
• Good racks that adjust to fit your real dishes and pots
• An energy-efficient rating to keep running costs low
• A filter you can clean by hand, rather than a grinder

Rinse Aid, Salt, and Little Extras

A handful of inexpensive extras keep a dishwasher running its best. None are complicated, and a small basket of them under the sink means you are always ready.

Not every machine uses dishwasher salt. It is common on some models with a built-in water softener and unnecessary on others. Check your manual, and if it does not mention salt, you do not need it.

• Rinse aid, the biggest help for spot-free, dry dishes
• Dishwasher salt, if your model has a softener that calls for it
• A monthly dishwasher cleaner to cut grease and freshen it
• A soft brush for the filter, the seal, and the spray arms
