Plates and pots on the bottom facing the center, glasses and plastics on top, nothing blocking the spray arms or the detergent door. Knowing how to load a dishwasher comes down to two ideas: water has to reach every surface, and hollow things have to face down.
The fiddly part is rarely the washing. Everything on my food processor is dishwasher safe, and getting it all in is the awkward bit rather than the cleaning.
Quick Answer
Bottom rack takes plates, bowls and pots angled toward the center spray. Top rack takes glasses, cups and anything plastic, away from the heating element. Face hollow items down, keep tall items from blocking the upper arm, do not nest spoons, and leave the detergent dispenser door free to open.
Key Takeaways
- Angle every soiled surface toward the center of the rack.
- Hollow items face down or they fill with water.
- Spin both spray arms by hand before you start the cycle.
- Plastics belong on the top rack, away from the element.
- Do not let anything block the detergent door.
- Nested spoons come out dirty. Alternate them.
- Sharp knives are a separate question from cutlery.
| Item | Where | How |
|---|---|---|
| Dinner plates | Bottom rack | Soiled face toward the center |
| Bowls | Bottom or top | Angled down, not flat |
| Pots and pans | Bottom rack | Face down, at an angle to drain |
| Glasses and cups | Top rack | Upside down, between tines |
| Plastic containers and lids | Top rack | Away from the heating element |
| Cutlery | Basket | Alternate directions, do not nest |
| Sharp knives | Usually by hand | Edges dull and it is a safety issue |
| Baking sheets and boards | Bottom, outer edges | Upright, never blocking the arm |
Step by Step
- Scrape, and rinse only what needs it. Bones, pits, seeds and labels come off. A heavy pan is worth a rinse.
- Load the bottom rack first. Plates in the tines, soiled faces pointing toward the center.
- Angle pots and pans face down. Flat means a pool of water sitting there at the end.
- Keep the outer edges for tall flat things. Baking sheets and cutting boards go at the sides, not the front.
- Load the top rack with glasses inverted. Between the tines rather than over them, so they do not rock.
- Put every plastic item up top. The heating element in the base is what warps them.
- Fill the cutlery basket alternating. Spoons facing opposite directions so they cannot nest.
- Check the detergent door. Nothing leaning against it, or the detergent never reaches the wash.
- Spin both spray arms by hand. Upper and lower. If anything catches, move it.
- Unload the bottom rack first. Otherwise water pooled on upper items drips onto dry ones below.
How This Goes for Me
Everything on my food processor is dishwasher safe, and getting it all in is the fiddly part rather than the washing. That is the loading problem in one sentence.
The dutch oven gets rinsed and then goes in. The bread machine pan is the same, loaf out, pan out, rinse, then in.
The indoor grill plates are removable and they go in too, which is most of the reason cleaning the grill is not something I think about.
My dinner plates came as a set years ago, and they seat properly in the rack. After several years that is the thing I would actually check for if I were buying again, which is not something that occurs to anyone in a store. Our roundup of dinner plates covers that fit question, and our guide to cleaning a food processor covers the awkward-parts problem directly.
Spray Arms Decide Everything
Why the angle matters
Water comes from rotating arms below and usually above. It sprays upward and outward, so a surface facing away from the center gets less of it.
What blocks them
A tall glass, a cutting board laid flat, a pot handle hanging low. Any of those stops an arm mid-rotation and half the load comes out dirty.
The one-second check
Spin each arm with a finger before closing the door. This is the highest-value habit in the whole process.
Blocked holes are different
If the arms turn freely and results are still patchy, the holes themselves may be clogged. Our roundup of dishwasher safe cookware covers pieces sized to sit without fouling the rotation.
Hollow Things and the Water They Hold
Anything with a concave surface facing up finishes the cycle holding water. Cup bottoms, bowl bases, mug rims and pan lids are the usual offenders.
Angling rather than laying flat is the fix, and most racks have tines set at a slope for exactly this reason.
Tall items at the front of the bottom rack also catch water dripping down as the door opens.
The unload order matters as much as the load order. Bottom rack first, always. Our roundup of drinking glasses covers shapes that drain rather than pool.
What Should Not Go In At All
Sharp knives dull against other items and against the basket, and a blade pointing up in a basket is a genuine hazard when you reach in.
Cast iron loses its seasoning. Wooden boards and handles crack and dry out. Anything with a glued joint can come apart.
Thin aluminum discolors, and metallic trim on dinnerware degrades over repeated cycles.
Insulated bottles with a sealed vacuum layer can fail from the heat. Our guide to whether you can put knives in the dishwasher covers the knife question, our guide to whether mason jars go in the dishwasher covers glass jars, and our guide to putting indoor grill plates in the dishwasher covers removable plates.
Overloading and Underloading
Overloading is the common error and it produces the complaint that the machine does not clean well. Items shielding each other is the mechanism.
A plate leaning against another plate has a dry face. That face comes out exactly as it went in.
Underloading wastes a cycle of water and energy, which matters less than most people think but is still a waste.
The target is full but with gaps, where nothing touches anything else broadly. Our guide to how many pots and pans you actually need covers owning less so a load fits properly.

Frequently Asked Questions
How do you load a dishwasher?
Plates, bowls and pots go on the bottom rack with soiled faces angled toward the center. Glasses, cups and all plastics go on top. Face hollow items down, alternate cutlery so spoons cannot nest, and make sure nothing blocks the spray arms or the detergent door.
Which way should plates face?
Toward the center of the rack. Water sprays upward and outward from rotating arms, so a surface angled away from the center receives less of it. A plate leaning flat against another plate has a dry face that comes out unwashed.
Why do plastics go on the top rack?
Because the heating element sits in the base, and direct radiant heat is what warps and deforms plastic. The top rack is far enough away. It is also why plastics stay wet longest, since they hold little heat to evaporate water.
Should cutlery go handle up or down?
Forks and spoons clean better facing up, since the soiled end meets the water. Alternate their direction so they cannot nest, because nested spoons come out dirty. Knives are the exception, and sharp ones are better washed by hand.
What blocks the spray arms?
A tall glass, a cutting board laid flat across the rack, or a pot handle hanging low. Any of those can stop an arm mid-rotation. Spin both arms by hand before closing the door, which takes a second and prevents half a bad load.
Does overloading really matter?
Yes, and it is the most common cause of the complaint that a dishwasher does not clean well. Items shield each other from the spray. Aim for full with gaps, where nothing touches anything else across a broad surface.
Which rack do you unload first?
The bottom. Water pooled in cup bottoms and bowl bases on the top rack drips down when you lift them, and unloading the top first means it lands on dishes you were about to put away dry.
What should never go in a dishwasher?
Sharp knives, cast iron, wooden boards and handles, anything with a glued joint, thin aluminum, dinnerware with metallic trim, and insulated bottles with a sealed vacuum layer. Heat and detergent are harsher on those than a sink is.
