Consider which accessories might be beneficial. Many models can be supplied with a draining basket, chopping board and strainer bowls. A drainer extension can be useful for sinks without a drainer where worktop space is limited in a small kitchen.

When shopping for a new washer, look for a front loading (horizontal-axis) machine. This machine may cost more to buy but uses about a third of the energy and less water than a top-loading machine. With a front loader, you'll also save more on clothes drying, because they remove more water from your clothes during the spin cycle. Look for the Energy Star label.

A concealed heating element reduces the risk of lightweight plastic items such as children's drinking cups melting onto it after becoming dislodged mid-cycle. Limescale build-up is also prevented. Some manufacturers now produce models with the concealed heating element coiled around the water inlet pipe for further energy efficiency.
