Washing machines

If you’re buying a washing machine, there’s more to consider than just type, size and price.

Features

All machines have a range of cycle times to choose from.

If you're buying a front loader, a higher price generally means more features such as spin speeds and electronic controls.

If you're after a top loader, paying more should get you a machine that can adjust the wash to match the load size and maybe even the fabric. This can mean lower energy costs, lower water use and lower fabric wear. Be aware, though, that many top loaders aren’t gentle enough to wash “woollens” or “delicates”.

Tip: If there’s no "wool" or “delicate” cycle, you’ll have to adapt. You may need to use another wash cycle and shorten its wash time, lower the spin speed and/or set the water temperature to warm.

Spin efficiency

A spin speed of 1000rpm will remove a good amount of water. This cuts down on drying time, but could cause more creasing. Some models allow you to select a spin speed independently of the wash cycle.

Cold washes

Most laundry detergents are formulated to work in cold water (with a temperature between 15°C and 20°C). However, if you live in a cold climate, your machine may do a "controlled cold" wash where a small amount of hot water is used to lift the wash temperature to about 20°C. This helps the detergent dissolve properly.

If you have solar hot water, using it for warm and hot washes could save time (due to shorter wash times) and electricity. Most top loaders have tap connections for both hot and cold water. If you’d prefer a front loader, your options are limited: few front-loading models have dual connections. Even when they do, some draw in hot water only for a hot wash (60°C or hotter). For warm washes, they use their element to heat water.

Tip: Warmer water makes most detergents more effective – so for those really dirty loads, use a warm wash.

Water efficiency

A downside of front loaders and water-efficient top loaders is that they can produce stiff, rough or scratchy towels. For towels to fluff up nicely, they need to be immersed in water.

Also, if too little water is used for rinsing, you may find detergent residue on your laundry.

We test washing machines using their “normal” cycle rather than their water-saving cycle, so our water-consumption figures will often be higher than those stated on the mandatory water-efficiency labels. Nevertheless, our test results can help you choose a machine that’s good at rinsing while still being water-efficient.

Auto dosing

Many manufacturers now have machines with automatic detergent dosing, usually in their higher end models. With auto dosing the user fills the dosing compartment to the top with liquid detergent, and the washing machine then automatically doses the correct amount of detergent depending on the weight of the load, the selected program, type of fabric and some systems even adjust for the degree of soiling. Advantages of this system are that you will likely use less detergent and save water due to less rinsing required, but it’s also way more convenient to not have to load the detergent drawer for every wash.

Out of balance

Machines without this feature will stop when laundry clumps excessively. Those with this feature gently agitate the load to re-arrange it – a valuable option if you put on a load overnight and want to ensure you’ll be able to hang it out before you go to work.

Available space

Figure out how much space you have before buying a washing machine. The dimensions (HxWxD) provided by the manufacturer are for the appliance itself, but you’ll need some wiggle room during installation. And don’t forget the plumbing: check how far the hoses, cords and plugs extend and add that measurement, plus a bit more for airflow, to the stated depth.

Washing machines tend to vibrate, especially during the spin cycle, so leave at least 5cm on each side to accommodate any movement.

Also consider potential obstructions. If you have a top loader, will you be able to open the lid fully and reach inside without banging your head on a cabinet or shelf? With a front loader, will wall mouldings, for example, prevent the door from opening properly?

Capacity

To calculate what capacity washing machine you need, weigh the maximum load you wash. If you have a set of bathroom scales, hop on with an empty washing basket for the base reading, then fill the basket with the maximum amount you’d wash at one time. Get back on the scales with the full basket, then subtract the first measurement from the second to get your load weight. Now you know what capacity you need.

Warranties

The majority of manufacturers offer a 2 year warranty with their machines, but some also have additional motor warranties, usually of 10 years. A motor replacement can be expensive so you should take these warranties into consideration when deciding which model or brand to buy. Warranty information is displayed in our test results. Remember that any warranty offered is in addition to your rights under the Consumer Guarantees Act.

Testing washing machines is expensive, and our laboratory has limited capacity. We survey the market and try to test as many popular models as possible, but we might not have tested the model you have seen on special. We can still help. Look at the results for similar models by that manufacturer, and check out our Top Brand awards and brand reliability data below.

The Energy Rating Label has a scale of stars to show how energy efficient a model is, compared to other models of the same size/capacity.

More stars = more energy efficient.

The energy consumption figure is in kilowatt-hours (kWh) and you can use this figure and the cost (tariff) from your latest power bill to calculate how much this model will cost to run. The MBIE-reported national average cost of a kWh in New Zealand is 29¢.

Lower kWh = cheaper to run.

Washing machine annual energy consumption in kWh is based on standards testing, assumes 365 uses a year and is for a warm wash.

You should only compare star ratings of washing machines with the same or similar capacities.
