How to Load a Dishwasher Correctly: The Complete Guide
Most Australians use a dishwasher every day, yet many don't know how to load it properly. Poor loading leads to dirty dishes, broken glassware and wasted water. Here's the complete guide to getting it right.
The Golden Rules of Dishwasher Loading
1. Scrape, Don't Rinse
Modern dishwashers are designed to handle food residue. Scrape large chunks of food into the bin, but don't pre-rinse. Pre-rinsing wastes water and can actually make your dishwasher less effective — some detergents need food particles to activate properly.
2. Bottom Rack: Plates, Pots and Pans
The bottom rack gets the most water pressure. It's the place for:
- Dinner plates — face inward toward the spray arm
- Pots, pans and baking trays — angle downward so water drains off
- Large bowls — face down and inward
- Cutting boards — stand upright on the side
Important: Never block the spray arm. Give it room to spin freely.
3. Top Rack: Glasses, Cups and Plastics
The top rack uses gentler water pressure, making it ideal for:
- Wine glasses and mugs — upside down, angled slightly to prevent water pooling
- Plastic containers — upside down and away from the heating element
- Small bowls and saucers — facing down
- Tupperware — secure so it doesn't flip and fill with water
4. The Cutlery Basket
Alternate forks, spoons and knives pointing up and down to prevent nesting. Always place sharp knives point-down for safety. Some dishwashers have a cutlery drawer on the top rack — lay items flat with handles accessible.
What NOT to Put in a Dishwasher
Not everything is dishwasher safe:
- Cast iron — will rust and lose its seasoning
- Non-stick pans — high heat and detergent degrades the coating
- Wooden items — warping, cracking and splitting
- Crystal and hand-painted china — too delicate for machine washing
- Copper items — will tarnish and discolour
- Insulated mugs and water bottles — high heat can damage the insulation
Detergent Tips
Use the right amount — more is not better. Overdosing leaves a white residue on glassware. Use a dishwasher-specific detergent (not washing up liquid), and use rinse aid for spot-free drying. Tablets are convenient, but powder or gel gives you more control over quantity.
Temperature Settings
- Eco cycle (40–50°C) — for lightly soiled loads, saves energy
- Normal cycle (55–60°C) — everyday dishes
- Intensive/Heavy cycle (65–70°C) — pots, pans and heavily soiled items
Maintaining Your Dishwasher
To keep it running well:
- Clean the filter monthly — unscrew and rinse under the tap
- Run an empty hot cycle with dishwasher cleaner once a month
- Wipe the door seal to prevent mould
- Check the spray arms for blocked holes and clear with a toothpick
