How to Choose the Right Dishwasher for Your Household Size
Buying the wrong size dishwasher means you are either running it half-empty every day (inefficient) or running multiple cycles per day (exhausting). This guide helps you match dishwasher capacity to your actual household needs.
Understanding Dishwasher Capacity: Place Settings
Dishwasher capacity is measured in "place settings" — each place setting represents one full set of crockery for one person: a dinner plate, side plate, bowl, cup/mug, and cutlery. A 15-place-setting machine can hold crockery for 15 people in one load.
Matching Capacity to Household Size
| Household Size | Recommended Capacity | Dishwasher Format |
|---|---|---|
| 1–2 people | 8–10 place settings | 45cm slimline or compact 60cm |
| 3–4 people | 12–13 place settings | Standard 60cm |
| 4–6 people | 14–15 place settings | Standard 60cm (full size) |
| 6+ people or frequent entertaining | 15+ place settings | Full 60cm with 3rd rack, or 2 x DishDrawers |
Dishwasher Formats Explained
45cm Slimline Dishwasher
Fits in a narrow underbench space. Approximately 9–10 place settings. Ideal for 1–2 person households in apartments or small kitchens. Bosch and Miele make excellent 45cm models. The tradeoff is smaller capacity and usually fewer wash options.
Standard 60cm Dishwasher
The most common format. 12–15 place settings depending on the model. Fits in a standard 60cm cabinet space. The best value for most households.
Fisher & Paykel DishDrawer
A unique format: one or two independent drawers. Each drawer holds 7 place settings and can be run independently. A double DishDrawer holds 14 place settings and you can run just one drawer for small loads. Excellent for 2–4 person households that run smaller, more frequent loads.
Key Features to Prioritise
3rd Cutlery Rack (Top Drawer)
Most Bosch, Miele and AEG models over $1,200 have a narrow 3rd rack above the main racks for cutlery and long utensils. This frees up space in the main racks significantly and is worth having.
Drying Technology
Some dishwashers use condensation drying (passive, results vary for plastics); Bosch uses Zeolite (best for plastics and all materials); Miele uses AutoOpen (door automatically opens at cycle end). For households with lots of plastic containers and baby bottles, drying performance matters.
Noise Level
Dishwashers range from 38 dB (barely audible) to 52 dB+ (clearly audible). For open-plan kitchens or running overnight, 42 dB or lower is recommended. Bosch, Miele and Siemens lead in quiet operation.
Auto Detergent Dosing
Bosch Serie 8 (i-DOS) and Miele G7000 (AutoDos) automatically dose the right amount of detergent for each cycle. Saves money and always ensures the correct dosage. Worth having if you are buying at this price point.
