Buying a dishwasher isn’t just about convenience—it’s about choosing the right size, features, and efficiency for your household. With so many models available, understanding what actually matters can save you money, space, and water in the long run.
This guide breaks down the key factors you should look at before buying a dishwasher, especially for modern homes and apartments.
1. Dishwasher Size: What Fits Your Kitchen and Lifestyle
Dishwashers generally come in three main sizes:
Full-Size Dishwasher (60 cm)
-
Best for families (4–6 people)
-
Fits 12–14 place settings
-
Ideal if you cook often or entertain guests
Slimline Dishwasher (45 cm)
-
Suitable for smaller households (2–3 people)
-
Fits 8–10 place settings
-
Saves space without sacrificing core functionality
Compact / Countertop Dishwasher
-
Great for studios or small apartments
-
Fits 4–6 place settings
-
Minimal installation required
What matters most:
Choose based on daily usage, not maximum capacity. An oversized dishwasher wastes water and energy if it’s rarely full.
2. Programs & Wash Cycles: More Isn’t Always Better
Modern dishwashers come with many programs, but only a few are used regularly.
Essential Programs You Actually Need
-
Eco Mode – Uses less water and electricity (best for daily use)
-
Auto / Sensor Wash – Adjusts water and temperature automatically
-
Intensive – For pots, pans, and heavy grease
-
Quick Wash – Lightly soiled dishes in 30–45 minutes
-
Normal – Balanced everyday cleaning
Nice-to-Have (But Not Critical)
-
Glass care
-
Hygiene / high-temperature wash
-
Half-load option
-
Delay start
What matters most:
Good cleaning performance on Eco and Normal modes, not the total number of programs.
3. Water Usage: Dishwashers Are More Efficient Than Handwashing
A common myth is that dishwashers waste water. In reality:
-
Modern dishwashers use ~8–12 litres per cycle
-
Handwashing can use 30–60 litres for the same load
What to Look For
-
Eco mode water consumption
-
Sensor-controlled wash cycles
-
High water-efficiency ratings
What matters most:
Lower water usage per cycle, not per hour. Eco programs may take longer but use significantly less water.
4. Energy Efficiency: Long-Term Savings Matter
Dishwashers run frequently, so energy efficiency affects your electricity bill over time.
Key Indicators
-
Energy rating label
-
Inverter or efficient motor technology
-
Eco wash performance
Tip:
A more energy-efficient dishwasher may cost slightly more upfront but saves money over its lifespan.
5. Noise Level: Especially Important for Open-Concept Homes
Noise is often overlooked until the dishwasher is installed.
-
≤45 dB – Very quiet (ideal for open kitchens)
-
46–49 dB – Acceptable for most homes
-
≥50 dB – Noticeable during operation
What matters most:
If your kitchen is close to living or sleeping areas, noise level matters more than extra features.
6. Built-In vs Freestanding: Installation Considerations
Built-In Dishwasher
-
Seamless kitchen look
-
Requires proper cabinet space and planning
-
Popular in modern kitchens
Freestanding Dishwasher
-
Flexible placement
-
Easier replacement
-
Ideal for rental units or existing kitchens
What matters most:
Choose based on kitchen layout and renovation plans, not aesthetics alone.
7. What Matters Most When Choosing a Dishwasher
If you remember only one thing, focus on these four essentials:
-
Right size for your household
-
Strong Eco & Normal wash performance
-
Low water and energy consumption
-
Reliable brand with local support
Extra programs and smart features are bonuses—but they shouldn’t be the deciding factor.
Final Thoughts
A dishwasher is a long-term appliance that should simplify your life, not complicate it. By choosing the right size, prioritising efficiency, and focusing on features you’ll actually use, you’ll get better performance, lower bills, and a quieter kitchen.
