How to Load a Dishwasher Correctly: Tips to Get the Best Wash Every Time
Most people assume a dishwasher will clean whatever you put in it. The reality is that how you load a dishwasher significantly affects cleaning performance. Poor loading leads to dishes that come out cloudy, food residue that doesn't wash off, and glasses that get broken from rattling against each other. This guide explains the right way to load every type of item for the best wash results.
The Core Principle: Water Must Reach Every Surface
Dishwasher spray arms rotate and direct high-pressure jets of hot water upward from the bottom and down from a middle arm (and sometimes a third arm at the top). For every dish to be cleaned properly, water needs an unobstructed path to its surface. Loading decisions should always be made with this in mind.
Bottom Rack: Plates, Pots and Pans
- Plates: Stand plates vertically in the tines with the soiled face angled toward the spray arm (which is below them). Most dishwashers have the main spray arm in the centre-bottom, so face plates inward toward the centre.
- Pots and pans: Place face-down at an angle so water can reach the inside and drain easily. Don't nest them together — nested pots won't get clean.
- Bowls: Angle face-down so they drain rather than catch water and emerge still dirty inside.
- Avoid overcrowding: Plates should not touch each other. A full but correctly spaced load cleans better than an overloaded one.
Top Rack: Glasses, Cups and Smaller Items
- Glasses and cups: Place upside down at an angle in the tine forks. Angled is important — flat upside-down glasses trap water that sprays from below, leaving puddles on the base of the glass.
- Mugs with handles: Position so the handle faces the same direction as the rack row for maximum stability.
- Plastic containers: Top rack only (away from the bottom heating element). Secure lightweight items so they don't flip and fill with dirty water.
- Large spoons and spatulas: Lay flat across the top rack tines.
Cutlery Basket
- Forks and spoons: Mix handles-down and handles-up for best water coverage. Avoid nesting spoons together (they'll come out dirty where they touch).
- Knives: Handles up, blades down for safety.
- Avoid overloading: Cutlery items should be loose enough to move freely.
What Not to Put in the Dishwasher
- Cast iron: Will rust. Wash by hand.
- Non-stick pans: Dishwasher detergent can degrade non-stick coating over time.
- Wooden items: Warping and splitting from repeated hot water exposure.
- Crystal and fine china: Risk of etching from detergent, thermal stress from heat.
- Aluminium: Can discolour and pit.
- Copper: Can tarnish.
- Sharp knives: Dishwasher detergent dulls blades. Hand wash good knives.
Pre-Rinsing: Don't Bother
Modern dishwashers are designed to clean dishes with normal food residue. Pre-rinsing is not necessary and wastes water. Scrape (don't rinse) plates into the bin before loading. Dishwasher detergents actually require some food residue to activate properly — completely clean plates can lead to detergent over-sudsing. The exception is large chunks of food that might clog the filter.
Rinse Aid and Salt
Rinse aid helps water sheet off dishes rather than forming droplets, reducing spots on glasses and improving drying performance. Keep the rinse aid reservoir topped up — your dishwasher will indicate when it needs refilling.
Dishwasher salt (for machines with a salt reservoir — most European brands) regenerates the water softener, reducing limescale buildup in hard water areas like much of Sydney.
Filter Cleaning
Clean the dishwasher filter every 2–4 weeks. A blocked filter reduces wash performance and can cause drainage issues. It takes less than 5 minutes: remove, rinse under the tap, replace.
